According to Aberdeen Proving Ground, Maryland - More than a month after revelations that a flaw in the U.S. military's electronic warfare toolkit caused him to lose sleep, Undersecretary of the Army Gabe Camarillo said the service provides powerful military signal jammer.

This week, the Army demonstrated its multifunctional electronic warfare aerial large pod in Aberdeen, Maryland. After decades of focusing on counterterrorism, the service is rebuilding its electronic warfare arsenal to counter less technologically savvy troops. U.S. officials say attacks on communications and other networks are seen daily in the war in Ukraine, adding to the sense of urgency.

Electronic warfare is a fight for control of the electromagnetic spectrum, which the military uses for situational awareness, communications and weapons guidance. The race becomes increasingly important as more advanced technologies are deployed on the battlefield and troops try to minimize signatures to avoid detection.

"My constant concern is that over time we have to keep up with the threat," Camarillo told reporters on Aug. 23 after a morning briefing. "I'm very impressed with the MFEW program the Army has, the different configurations and the direction it's going."

Officials said Tuesday that MFEW-AL is an option as long as power and Ethernet ports are available.

"We want to be platform-agnostic. For other platforms, we can offer a smaller form factor if needed," said William Utroska, head of the Intelligence, Electronic Warfare and Sensors Program Executive Office. "We're working with the Future Vertical Lift cross-functional team because they have electronic warfare requirements and they know we've got a lot of work ahead of schedule."

Camarillo said he saw one of the prototypes on site, courtesy of PEO IEW&S, and liked its open approach.

"I think this is an area where the Army is heading in the right direction," Camarillo said. "It allows us to not only see sensor payloads and EW payloads, but also how they fit into certain components, how we can plug and play over time, giving us the opportunity to do technology plug-ins and stay ahead of the curve. Threats may be, and also have the latest generation capabilities."

The Army is also pushing electronic warfare in other areas.
The service signed a $58.8 million contract with Lockheed in July to provide prototypes for the Ground Layer Systems Brigade Combat Team program. In August, it submitted deals to Lockheed and General Dynamics Mission Systems, respectively, for the ground-level system - the brigade upper echelon concept and demonstration.

Once implemented, these two systems will provide soldiers with electronic warfare, cyber and signals intelligence capabilities.

Now, with the development of the Internet, wifi has become an indispensable part of our lives, so do you know how to block wifi?
Many people have wireless routers at home to meet the needs of devices to access the Internet, which has also spawned a lot of people who surf the Internet. Isn't your home wireless network being used by others? Has your wireless broadband been "rubbed" by others? How to block wifi from others?

First enter the web configuration interface of the wireless router AP, find the basic settings menu to modify the SSID name, select Disable SSID broadcast, then modify the default IP address of the wireless router AP, turn off the DHCP function, and adjust the wireless transmit power to control the wireless network coverage.

Enter in the IE address bar, and then see the password and user name, both are admin. This will allow you to see the currently connected project. If there are redundant devices, they will be cleared. If it is a wireless router, it is best to turn off the wireless broadcast.
Step 1: Turn off SSID (network name) broadcast
After turning off the SSID broadcast of the wireless router AP, it is difficult to find this wireless network when searching for wireless. The setup method is very simple. Enter the web configuration interface of the wireless router AP, find the "Basic Settings" menu, modify the SSID name in it, and then select "Disable SSID Broadcast".

Step 2: Turn off the DHCP function

After turning off the SSID broadcast, we also need to turn off the DHCP function, which means that the wireless router/AP cannot automatically assign IP addresses to wireless clients. In order to further prevent being "robbed", we'd better modify the default IP address of the wireless router/AP. For example, the default IP address is:, we can modify it to Enter the web configuration interface of the wireless router/AP, find the "LAN Settings" menu, then modify the default IP address, and select "Disable DHCP Server" to confirm.

Step 3: Reduce the transmit power and upgrade the firmware

If some wireless routers/APs currently have the function of adjusting the wireless transmission power, the coverage of the wireless network can be controlled by adjusting the wireless transmission power, making it difficult to search for wireless signals. Upgrading the firmware of the wireless router/AP is also important, because it not only fixes some security holes, but may also add additional protection features for better security.

Generally speaking, you have to log into the router background to hide the wifi signal. You can hide the wifi signal by logging into the router management background and selecting wifi settings to turn off the ssid broadcast.
If you feel that the above steps are too many and too complicated, you can also consider buying a wifi signal jammer, which can easily help you solve the problem of being hacked on your network.

In recent years, there have been more and more application scenarios of wifi jammer. The most commonly used scenarios include: various examination rooms, examination rooms, various confidential institutions, various detention centers, prisons, drug rehabilitation centers and other detention and supervision places, etc. In general, the use of wifi jammer device in these units or places is legal, but there are also some places that are not suitable for use. So, what application scenarios should be avoided when using wireless wifi signal jammer?

From the demand consultation we received, some of the demands are obviously impure motives or illegal. For example, if you want to install a wireless wifi signal blocker on a transport vehicle, and turn on the device when being weighed by the weighbridge, so you want to block or interfere with the weighing data of the weighbridge. Another example: I want to install a wifi jammer in the power distribution room, or install it near the remote meter reading terminal equipment of the electric meter, to interfere and prevent the upload of the meter data. Another example: I want to use a wifi blocker on some engineering vehicles, especially to interfere with GPS positioning data, so that the superior cannot monitor the vehicle's running trajectory in real time.


Through the examples of various cases mentioned above, we can know that there are indeed a small number of people who want to use the working characteristics of the wireless wifi bluetooth jammer to consciously and targetedly avoid some supervision, or temporarily obtain a small number of people. benefit. These people have bad motives and even risk violating national laws and regulations. As a professional manufacturer of wireless wifi signal jammers, we must operate in accordance with the law and resolutely suppress these abominable acts similar to the above. So when we need to have such a demand, we will directly refuse.

wifi jammer might sound like something out of a movie, but someone might be near you right now! Here's what it's about and why you might need it too.
If you're someone who values ​​privacy, we live in dire times. You no longer know who is viewing what you search for and who they are selling that information to.

With the advent of cell phones and drones, it's hard to even get out of the house without the potential presence of being filmed or watched.

Thankfully, you're not alone in craving security through privacy. Technologies such as wifi jammer device, drone jammers, and cell phone jammers have entered the market in recent years. A wifi blocker is a signal-blocking device that transmits synchronized radio waves on the same frequency as a device such as a cell phone or drone to obscure its signal.

Jammers are primarily used to disable these devices and are increasingly used by companies and individuals.
What is a Wifi Jammer?

While a wifi disruptor might sound like something out of a spy movie, it's an increasingly popular device. Essentially, the technology is used to protect your privacy from hackers who use your phone to compromise your wifi.
These are favored by companies that handle sensitive information to prevent leaks. The 5GHz wifi scrambler has an effective range of up to 40 meters and will block WiFi and phone signals in a fixed space.

For something more mobile, the WiFi Mini Signal Blocker is much smaller and cheaper than 5GHz. This WiFi jammer is designed to be carried anywhere and provides 10 meters of protection no matter where you are.

This jammer is very effective if you're dealing with sensitive data away from your workplace or home (like a hotel or other more public place). With up to two hours of battery life on a full charge, it's also ideal for those who feel more comfortable with a little bit of a barrier between themselves and someone else's device.

You can think of wifi jammers as signal blocking devices. It transmits radio waves into the air at the same frequency as a cell phone. In this way, they can be seen as cell phone jammers. Therefore, anyone trying to use the phone within a certain number of feet will be blocked.

This helps keep any sensitive personal or business information safe when you access it. If you want to learn more about wifi frequency jammers, be sure to check out our guide here.

wifi jammer can be a useful device when used in the right context. Whether it's preventing unauthorized communications or helping reduce interference, jammers can do many things.
Today we're going to cover just a few of the ways cell phone jammers, GPS jammers, and wi-fi jammers can help you!
Prevent unnecessary distractions

According to a Pew Research Center poll, only 24 percent of employees believe their smartphone or cell phone is necessary for their daily work.
Granted, this information comes from employees rather than employers, but there's little reason to suspect it's far off. Cell phones are not required for most jobs.

Phones are tools, and like any tool, they can be used in productive and inefficient ways. If they become a problem in the workplace, employers can install wifi signal jammers to prevent them from causing problems.
If employees can't stop using social media sites or texting, this can be a good option rather than just start firing employees who break the rules. They can't use what they don't have access to.
forced quiet time
Some parents have started using wifi jammers to force their children to be quiet for a while. Jammers can be turned on, and WiFi, cell service, or both can be blocked.
While parents have to be careful about the strength of their wifi blockers (or they might get complaints from their neighbors), this can be a great way to make sure the rules are followed at homework or bedtime.
If this sounds extreme, remember that you can turn the wifi signal jammer off and on as needed. You can turn it off whenever the child in question is focusing on other things that don't really matter.
If this is going to become a habit, remember that you will also need to have a landline installed in case you need to take an important call or make an emergency call while the wifi jammer device is turned on.


Prevent interruption

While it's important to check local laws on the matter, there have also been cases of individuals installing jammers (most commonly wifi cell phone jammers) to prevent interference.
Whether it's a class, a lecture, or a religious service, calling the wrong time can be a huge distraction. Cell phone jammers can block these incoming calls in the first place.
The unfortunate reality of any large group is that telling people to mute their devices won't work. There are always a fair number of people who have their devices turned on for some reason.

We can debate whether this says something larger about society, but it's still true anyway. Even funerals aren't immune to strange calls to break silence or pray.
In any case, the signal jammer interferes with the frequency that the cell needs to receive calls, preventing the phone from ringing (because the phone doesn't get through in the first place).

Block unauthorized communications

This applies more to people who work in various government and correctional facilities, but signal jammers can block communications that could become a serious security problem.

Certain facilities require security for obvious reasons. For example, some military installations do not allow any communication without pre-approval to pass through.

Then there are prisons, where unauthorized lines of communication may help individuals facilitate crime even while behind bars. Not to mention they shouldn't have cell phones in the first place.

With careful selection of signal jammer locations, it is possible to block communication even in important areas of the facility, but not in other areas. That way, it's still possible to make calls or use WiFi in some places.

If you're a government worker or contractor, don't forget to check out our deals designed to help you get important work done on budget without sacrificing quality.

Block danger or crime signals
While somewhat related to the above point, it's worth noting that signal jammers are often used by law enforcement to create dead spots where phones, etc. may pose a threat.

The most straightforward approach in the past has been to block signals that could be used to detonate bombs remotely. These bombs require a wireless signal (usually a phone) that can be jammed like any other signal.
Less obvious is the jammer's ability to prevent criminals from calling in outside forces. This is useful in many situations, such as in raids or hostage situations. It helps prevent criminals from coordinating.

To be clear, these are tactics law enforcement and military personnel can use, but they are one of the most important uses of this technology. Done right, it can save lives.
Signal jammers can play a variety of roles, depending on the model purchased, where they are installed, and what people want out of them. They are used by everyone from military personnel to parents.
If your needs are more specific or are on a budget, explore our store Jammer mart! We're sure to have a model that's right for you.

Wireless technology has provided us with many conveniences, such as being able to use the Internet and telephone without being tethered to wires. Some companies are trying to take advantage of the technology by releasing products that allow you to "cradle" your phone into a unit while still giving you access to the internet. This is known as the benefit of wifi jammer. If you own a Motorola phone, you've seen commercials for this product on TV and the Internet. This is a great project for parents looking to keep their kids safe when they're out and about, or for any business that might want to promote cell phone hubs from a distance, such as from a plane. In this article, you will learn about the benefits of wifi signal jammer.

Many people don't know how this wifi jammer device works. This essentially means that you can use your phone or PDA device to connect to the hotspot just like any other wireless device. However, if you don't have a wireless signal or your PDA has only a weak signal, the device won't be able to connect to the network. The device uses a WiFi protection system module that sits between the phone and the router or modem.

There are some advantages to using this type of wifi frequency jammer. You can keep your kids safe, your laptop safe, or your PDA from being stolen. You can also prevent the interruption of internet service. For businesses, it can help improve reception and increase internet speed.

There are also some disadvantages. It takes longer for the device to detect the network because it has to scan all radio channels. Nor does it protect your data from intrusion or corruption. This is something to consider if you want to use this device for work or your phone.

When you install Hamster on your desktop or laptop, you can turn off the internet to the rest of the machine so it's not vulnerable.

Can signal blocker really block all signals?

Although the time for the college entrance examination has indeed been delayed due to the pandemic in recent times, corresponding measures have not been reduced in order to ensure the safety of the examination room details. Operators have actually released news one after another. During the exam, according to the needs of the Education Bureau, the cordless signal wifi blocker will definitely be turned on, which will inevitably affect the interaction quality of mobile phone users throughout the school. Communication will not return to normal until the end of the test. What are the characteristics of the signal blocking device for the entire process of the college entrance examination? The invigilator at the entrance of the examination room waved a metal detector. Is it really useful?

To understand the function of blocking mobile phone signals, let's first understand how mobile communication works.

As a mobile communication tool, mobile phones need to first establish a link with nearby base stations, and then connect to the core network to discover interactive destinations. In the above process, all information is carried and transmitted by electromagnetic waves. The frequency band of electromagnetic waves used in mobile phones is related to the requirements of the phone and the operator. But overall, the electromagnetic wave patterns used by the three major operators are distributed in the frequency range of 850-4900MHz. If the organizer of the college entrance examination wants to block the mobile phone signal inside the examination room, the 2G/3G/4G/5G base station near the evaluation room cannot be disabled, otherwise all communication devices in this area will not have the ability to connect normally. This is the only way to block mobile phone signals in the exam area.

The most popular 8 band jammers

High power mobile phone jammer, also known as mobile radio signal jammers, are types of devices used to disperse and interfere with almost all incoming signals from relevant network service providers, so only certain devices have resistance to this, most of which are unlikely to be encountered by you no matter what. A high-power mobile phone blocker is an electronic device that can block mobile phone signals within a specific radius range. A high-power mobile phone blocker is an electronic device that can block mobile phone signals within a specific radius range. It blocks high range signals. It is very simple to use to block movement signals. High power mobile phone blockers can block signals up to 40 meters long.

When it comes to blocking smartphone signals, the first thing that comes to mind is metal reinforcement, which means placing the phone in a closed steel box and using steel to block the spread of electromagnetic waves. However, it is clearly unwise to set all levels of the evaluation area to metal enclosed levels. So what should we do? It's very simple, just a small mobile signal gsm blocker is needed to block all smartphone signals in the exam room.

The smartphone signal blocker checks the RF frequency band of the forward channel (base station to mobile phone network) at a certain speed throughout the entire working process, causing interference during the process of obtaining messages through the smartphone signal, ensuring that the smartphone cannot detect signals from the base station. Typical data transmission makes it impossible to establish a link with the base station, and there is also a state of no signal or solution. For example, when a mobile phone interacts with a base station, the signal blocker acts like an instigator, deliberately making sounds around you. The sound signal is too loud, and the phone cannot hear what the base station is saying, nor can the base station hear what the phone is saying.

Desktop  Jammers

At present, the mobile signal blockers used in the evaluation area are in the regular frequency band, which can block all the 2G/3G/4G/5G frequency bands of operators, as well as all Wi Fi and Bluetooth signals. The above is the concept of a mobile phone signal gps blocker. However, the frequency range of electromagnetic waves ranges from a few Hz to hundreds of GHz, and each segment can be used as a signal for interaction. Will the evaluation room use some special regular frequency bands? This applies to various other radio communication tools, as well as radio interaction devices with fixed frequency bands that have emerged in this situation. The operating frequency band of these devices is selected outside the regular array covered by the mobile phone jammer,

For this special radio communication equipment, the assessment room is equipped with a monitoring vehicle equipped with a radio display for real-time monitoring of unknown radio wave signals. So how precise is the function of a radio detector?

  1. Due to the characteristic of electromagnetic waves being "large in the near and small in the far", by constantly moving the detection vehicle, tracking tools can locate the signal transmitter based on the distance and signal strength, and catch violators using these radio interaction tools on the spot.

  2. Nowadays, drones have truly appeared in the college entrance examination area, allowing for faster signal delivery.

Read on to learn how to use a Bluetooth jammer to prevent unwanted calls.

GPS jammer

If you're wondering how to use a GPS jammer, you're not alone. Many civilians are looking for GPS jammer devices to maintain their privacy in a world where everyone is constantly tracking their every move. However, most people don't have the technical know-how to make their own jammers that go beyond simple radio jamming. To ensure your privacy, read on to learn how to use a gps blocker in your own home.

GPS jammers can be made of copper or silver, and they interfere with GPS signals. Most GPS jamming gadgets are sold online. You need to connect it to an adapter for it to work. Depending on which GPS signal you want to jam, the device will jam signals within a certain range. That means GPS tracking of company cars will be hampered. However, you should be aware of the potential dangers and consequences of doing so.

How to Stop WiFi Jammers

The illegal use of signal blocker can have many consequences, including serious hazards to public safety. In addition to disrupting traffic, cell phone use can interfere with GPS and WiFi signals, as well as police radar.

Whether you're looking for some peace and quiet, jamming your phone can have devastating consequences.

Stationary wifi jammers are more powerful

Stationary WiFi jammers interfere with multiple signals. It may interfere with WiFi and Bluetooth. Some jammers have built-in detectors to identify the signals they can jam. These types are more powerful and more expensive than single channel occluders. Cheaper models work by selectively transmitting specific messages. They only work for a short time and cover a small area. Also, these devices cannot jam all signals effectively.

broadcast radio signals on the same frequency

If you've been wondering how to stop wifi from interfering with your devices, it's not as difficult as you might think. A wireless jamming device is a device that broadcasts radio signals on the same frequency as a wireless network. While they are illegal in many countries, they can easily be replaced with your own WiFi router. The mobile jammers frequency range can be adjusted, so you can block or disable other networks.

Mylar Blanket Blocks Wi-Fi

Mylar blankets can block Wi-FI signals. Just make sure to place them with the aluminum side facing out. These blankets won't block the entire signal, but they will block most of it. Another great way to block the signal is to cover internet routers and other electronic devices. Aluminum foil also helps prevent signal eavesdropping.

Memorial Day Deals

This is important to us because it allows us time to celebrate and honor the brave men and women who gave their lives for our country and our freedom.

Cell Phone and WiFi Jammers

The range of cellular and wifi jammers may vary depending on their power and surroundings. It can block signals from many different types of networks at the same time. Low-powered devices can only jam signals up to 30 feet away, while high-powered jammers can make cell-free areas the size of football fields. Law enforcement jammers can shut down service for up to a mile. These devices can be placed in many places, depending on your needs.

One of the reasons people use cell phone and wifi jammer is to prevent people from using their smartphones and social media without their permission. However, some have reported that their neighbors use jammers to prevent their teenage children from accessing the Internet without their permission.

Cell phone and wifi jammers work by blocking radio and cell phone signals. It interferes with these signals and blocks their reception. These devices block signals from cell phone towers, cutting out all but the most important signals. So, cell phone jammer blocks calls and text messages. The phone will not display the signal bar. It will stop responding to calls and won't even register calls. Therefore, people who buy mobile phones and wifi jammers will be protected from harassment or even harm by others.


Jamming Cell Phone Signal

  1. Jamming cell phone signals is a multi-billion dollar industry. Many people have tried this approach with varying degrees of success. A jammer is a device that covers an area, denying service to everyone. Some have even suggested disrupting movie theaters, highways and school systems to prevent emergency services from reaching those areas. However, these methods are controversial because some countries do not regulate them.

  2. A Tampa Bay-area school used a cell phone jammer during a recent incident, but officials are cautious about the device's effectiveness. While it's illegal to use cellphones in schools, a Florida principal is using cell phone jammers in his classroom. After noticing students using cell phones in class, he decided to use a cell phone jammer in class.

  3. The South Carolina Department of Corrections is currently awaiting test results that will reveal whether the technology works. State prisons are common targets for cell phone jammers. They are also a potential source of revenue for the company, which sells its equipment to federal agencies. However, many industry spokespeople have warned that the technology could have a negative impact on the public. If the technology works well, it could be used as a crime-fighting tool in prisons.

  4. Cell phones are a convenient convenience, but a nuisance to other patrons. They keep the lines busy while others get distracted by their phones. Customers will appreciate it if the cell phone jammer is left on the counter and will be happy to be free from the constant hassle. Although there may be some select customers who don't like the idea of being interrupted while waiting for their food.

GPS WiFi Cell Phone Jammer

How to Test a Cell Phone Jammer

Cell phone jammers interfere with GPS

If you're wondering if cell phone jammers can interfere with GPS, the answer is yes. GPS receiver signals from satellites 13,000 miles away are very weak. Small jammers can disrupt signals from miles away. gps jamming signals can be a crime because some people use them to smuggle drugs or steal cars. Others use jammers to gain extra time.

Jamming cell phones has a wide range of applications. Some people want to block unwanted calls, while others are just looking for a little peace and quiet. However, be sure to check local laws and regulations before you start jamming any frequencies. It's also important to remember that cell phones are analog devices, so they're just as susceptible to interfering devices. However, if you intend to interfere with your phone's GPS signal, it's best to purchase equipment specifically designed for this purpose.

Interfere with Wifi

WiFi cell phone jammers are an excellent way to block wireless signals. These devices have several advantages. They can be easily installed and have good cooling properties. They block signals from all cell phone bands and can be configured to accommodate a variety of power supplies, antennas, connectors, and operational needs. You can choose which frequency bands to jam. The devices have a two-hour battery life, enough to block signals up to 50 meters away.

Most can interfere with six frequencies: 850 MHz, 900 MHz, 1700 MHz, and 1800 MHz. High Power WiFi Cell Phone Jammer is capable of jamming two signals at the same time. Blocks up to 25 meters and is extremely portable. Jammers can be worn on a person's arm, which is useful for military and police use. The built-in battery is safe, portable and rechargeable.

Examples of Where Cellular Signal Blockers Can Be Used

Cellular signal blockers can be used in many different settings. They are useful for a number of reasons, such as blocking annoying calls in a noisy room. They can also keep rooms in schools or elderly homes quiet.

Another use for cellular signal blockers is in hospitals. Since cell phones are necessary for business, having someone on the phone can cause disruption. Many people use cell phone blockers to protect themselves from rude passengers. The technology sells for less than $200. Plus, it's easy to install. You can choose a jammer based on the area you plan to use. While it won't block all signals, you can choose a specific location for your device.

The EMP generator generates an electromagnetic pulse to disrupt electronics

U.S. Customs and Border Protection (CBP) officers in Wisconsin recently seized a slot jammer device while inspecting a shipment from Hong Kong.

CBP officers made the discovery at the Milwaukee port of entry on Feb. 4, CBP said in a press release.

The most popular 8 band jammers

Electromagnetic pulse (EMP) devices are banned by the Federal Communications Commission and are used to "interfere" with the inner workings of slot machines.

According to U.S. Customs and Border Protection, an EMP generator generates an electromagnetic pulse that can disrupt electronic devices at a range of about one meter. These devices typically send an electric current through a magnetic field via a magnetic copper wire.

Border Patrol agents in Arizona have shot dead Mexican migrants at the US border

CBP said the shipment was a car adapter from an electronics supplier in Hong Kong and was headed to a home in Mossini, about 175 miles northwest of Milwaukee.

"There are a variety of ways these tools can be used," LaFonda D. Sutton-Burke, Chicago's director of field operations, said in a statement. "Federal law prohibits such cellphone jammer because they can be used to interfere with radio communications, cellular phones, GPS and other communications devices."

CBP officers at the Port of Milwaukee Express Consignment Operations facility examined the shipment and sent it to the Mechanical Engineering Division at FBI Headquarters for further analysis.

Cell phone jammers in the country's prisons are not enough to stop criminals inside from sending messages to others outside the prison.

That's the view of senior prison officials, and while network jammers (which they say can be used) are used to block cell phone signals in prisons, other interception techniques are needed for the system to be effective.

"Cellphone jammers are being used. However, to be truly effective they must be used in conjunction with other technologies such as WiFi jammers. We can see this happening in other jurisdictions. But it still needs to be used correctly here.

"So some prisoners have mobile phones and tablets but are unable to make calls. However, you can use your phone's data allowance or if you have access to a hotspot device or WiFi box, you can also make calls through social media apps. This includes WhatsApp , Facebook and Instagram etc. So the problem of communicating with the outside world remains. Communication is still a work in progress.

"In other jurisdictions, you'll see cell phone jammers used in conjunction with other interception devices to determine what frequencies those devices are using and then target those specific frequencies." If it doesn't, it's almost like a dreidel in the mud, "a senior prison Service source explained yesterday.

Acting Commissioner of Prisons Deopersad Ramoutar did not directly answer questions put to him recently about the function of mobile phone jammer, saying it was confidential information and not within the purview of the Prison Service.

8 Bands Jammer Device

On July 5, several contraband items were found and seized at Aruka Maximum Security Prison, including a Wi-Fi box.

The officer received the information and went to the cell block B of the prison.

Police conducted a search and found and seized a bag containing 53 grams of cannabis, mobile phones and Wi-Fi boxes in a cell near the toilet.

In another cell, police found and seized a bag containing 104 packs of cigarettes and marijuana weighing a total of 241 grams.

Two prisoners said they were in possession of the seized items.

On Friday, prison officials expressed concern about the use of drones over prisons, with one senior officer saying it was a "ticking time bomb" that needed to be addressed.

"All it takes is a drone, we can't catch it, it could drop knives or even guns and we could have a very serious situation." Everything we've seized so far has been contraband - cigarettes, marijuana, cell phones, chargers, etc. But if we miss even one, it could be a very dangerous situation for the prison and for the country."

Ramutar said the prison service had noticed an increase in the number of drones being used around prisons, especially in the last year, and had taken action.

He said that with the help of various branches of the state security services, most of the items dropped from the prison walls were confiscated before they reached the prisoners.

How criminals use jammers device and defuses to compromise Wi-Fi security cameras

The new warning applies to anyone using wireless security cameras like Ring to protect their homes.

A Detroit woman says her Ring camera didn't capture the moment her car was stolen outside her home, and local experts say that's because criminals have become more tech-savvy.

wifi Jammer Device

Earlier this month, the woman said her car was stolen from her driveway and when she checked her Ring camera footage, she noticed the time was missing.

Chris Burns, owner of Techie Gurus, said security cameras that use Wi-Fi to record are more about convenience than safety. This is because Wi-Fi can easily be interfered with, preventing cameras from detecting people near your home, leaving criminals in trouble.

"Relying on wireless as a security aspect is a mistake," Burns said. "Wireless signals can easily be interfered with or blocked."

These scammers can use it like a WiFi jammer or deauther, which can be about the size of an Apple Watch.

If you stand close enough, the defuser will overload the WiFi system and force the WiFi camera to stop recording. Accessories only cost around $10 to $50. Jammers, on the other hand, cost between $150 and $1,000.

They are also extremely illegal, making jammers even harder to find. However, with the push of a button, powerful portable jammer can prevent WiFi security cameras from recording an entire street.

A Ring spokesperson issued a statement: "As with any Wi-Fi-enabled device, Wi-Fi signal interference can affect the performance of Ring devices. If customers are experiencing connectivity issues, we encourage them to contact Ring customer service."

How can customers protect themselves?

"For true security, it should always be hardwired, it should always be connected to Ethernet or something like that," Burns said.

A Ring spokesperson said that while the issue is well known, it is rare.

Burns said gps blocker are likely to become more popular as technology becomes cheaper, and it's important for people to be fully informed.

WINDSOR LOCKS: Tech-savvy burglars targeted homes in Connecticut and Massachusetts and broke into a home there after receiving details about the security systems from fellow homeowners, according to arrest warrants issued Friday.

Matthew Colon, 31, of West Springfield, Massachusetts, was arrested for conspiracy to commit first-degree burglary and conspiracy to commit second-degree burglary. Enrique Santiago, 37, of Springfield, Mass., was charged with first-degree burglary, possession of burglary tools, theft of a firearm and conspiracy.

Police said they expected to arrest a third man in the case, which was linked to other burglaries involving heightened surveillance and information about when the homeowner left, according to Colon's arrest warrant.

Early on May 20, 2022, a Green Manor Terrace resident called Long Island police to report that surveillance cameras showed two men walking through his backyard. The arrest warrant states that officers who stopped the burglary found a broken rear sliding glass door and a collection of discarded evidence near the home, including a Wi-Fi jammers, a portable radio, a glass punching tool, A crowbar and bolt cutters.

Power Adjustable Jammer

Burglars broke through the chain link fence and disabled security cameras with manual and Wi-Fi gps blockers, but the poolside cameras were beyond the phone jammer, Windsor Locks Detective Chief Jeff Lampson wrote in Windsor Locks range and continue recording. Affidavit Warrant. The homeowner reported $4,200 in cash missing, along with a man's watch, jewelry and his wife's 9 mm handgun, the search warrant said.

On May 26, a resident two doors down found a pillowcase containing a watch, a gun and other items the victims identified as belonging to them, police said. Police said the location of the bag of stolen goods and a backpack containing a WiFi jammer showed the thieves fled in different directions after the break-in.

Lampson said Friday that federal law prohibits the use or operation of jamming devices and that federal investigators are interested in the case. He said police in the area have noticed the devices are increasingly being used in burglaries.

In this case, however, police say it was DNA that led to the thief's demise. During a search of the Green Manor Terrace property on May 23, a homeowner told police she found a pair of gloves she had never seen before and handed them over to investigators. Police submitted swabs from the gloves and other evidence they suspected the thieves had come into contact with to the state forensic laboratory.

Lampson wrote in the arrest warrant that on Aug. 16, the San Diego lab reported "criminal conduct" with DNA on the gloves. Police said the same DNA was linked to two previous burglary investigations, including a 2010 car break-in in Middletown and a 2012 break-in in South Hadley, Mass., where a gun was stolen. Santiago was arrested in both cases, according to arrest warrants.

Santiago, through his attorney, told Windsor Lock investigators that a man who drove a black sedan and whose father owned a tuning company coordinated the break-in at Green Manor Terrace, the warrant said. When Lampson asked the homeowner if he knew anyone matching that description, the man immediately identified Colon, a co-worker at a home health care company in East Longmeadow, Mass., Lampson wrote in the arrest warrant.

The homeowner said he considered Colon a friend and told him about a trip to Long Island last May, the warrant said. The victim also said Colon and his father helped him remodel the home, the warrant said. He said Matthew Colon had been to his home multiple times and was aware of the security camera system, the warrant states.

When faced with the victim's statements and evidence of the burglary, Colon told police he was "tricked" into the burglary plan by a third suspect in the case.

The suspect's girlfriend also worked in home health care with the Colon and Windsor Locks victims. Lampson wrote in the arrest warrant that other workers at the company reported break-ins at their homes in Massachusetts, including one woman who said Colon had come to her home to help repair a gazebo before the break-in.

Cellphone records showed calls between Colon, Santiago and the unidentified suspect in the Windsor Locks burglary before and after the break-in, the warrant stated. Police said the third suspect is a felon with a long criminal record that includes armed robbery and numerous burglaries.

Santiago also has a long rap sheet, including convictions in Connecticut for burglary and larceny, the warrant stated. Massachusetts investigators said they believe he is part of a criminal organisation involved in targeted burglaries, according to the warrant. He posted US$150,000 bond and is scheduled to appear in state Superior Court in Hartford on May 31. Colon posted bond of US$100,000 and is to appear in court on May 2.

The so-called signal shielding means that the receiving device cannot obtain a signal with a signal-to-noise ratio that meets the signal identification requirements. Signal to noise ratio (Signal Noise Ratio, SNR) is the most important content.

We can refer to the formula:

SNR = \frac{P_{Signal}}{P_{Noise}}

Desktop  Jammers


Therefore, there are two ideas for reducing the signal-to-noise ratio:

  1. Reduce signal strength

  2. Increase noise intensity

Based on the above ideas, we can use signal jammers to interfere/shield wireless signals.

The function of a signal jammer is to shield signals and is used in many situations. Nowadays, information spreads very fast. With a mobile device, all kinds of information can be spread to every corner in an instant. For some occasions where information cannot be spread, mobile phone signal cellphone jammer are very necessary.

Within a certain frequency range, mobile phones and base stations are connected through radio waves to complete data and sound transmission at a certain baud rate and modulation method;

Based on the above communication principle, the Dazhan jammer scans from the small-end frequency of the forward channel to the big-end at a certain speed during the working process. This scanning speed can cause garbled interference in the message signals received by the mobile phone. The mobile phone cannot detect normal data sent from the base station, making it impossible for the mobile phone to establish a connection with the base station. Communication equipment exhibits phenomena such as searching the network, no signal, and no service system.

Basic principles of 5G shielding:

Mobile phone signal jammers (jammers) achieve interference and shielding of wireless communication signals by emitting co-channel interference signals. The transmit power of the wifi signal jammer directly affects the strength of the interference signal, thereby indirectly affecting the shielding effect of the signal jammer. There is a positive correlation between these three. In other words, the stronger the transmission power, the stronger the interference signal, and the better the theoretical shielding effect in the same environment.

What factors affect the shielding effect? In the actual use environment, the interference signal emitted by the mobile phone signal jammer is affected by various factors, the most important of which are the following:

  • The indoor jammer is recommended to be placed at a height of about 180cm-220cm above the ground, preferably at a forward angle.

  • Is there any obstruction (such as walls, metal products, human body, etc.) between the gsm signal jammer and the wireless communication device (mobile phone, etc.). The interference signal emitted by the jammer will attenuate to varying degrees after passing through the obstruction, so please try to avoid it.

  • The original wireless communication signal strength in the application environment of the jammer. The weaker the wireless communication signal strength in the use environment, the stronger the theoretical shielding effect of the jammer.

  • The distance between the application environment of the jammer and the communication base station. The farther the application environment of the jammer is from the base station, the stronger the theoretical shielding effect of the jammer.

A WiFi and bluetooth jammer Can Prevent Data Theft

It is important to understand that WiFi is available in 2 frequencies, 2.4GHz and 5GHz. While 2.4GHz is by far the most commonly used, some newer routers do include 5GHz.

Bluetooth is within the 2.4GHz band, so any WiFi jammer that covers 2.4GHz is also going to block Bluetooth.

military jamming

The next important consideration is the size of the coverage area needed for your application. We offer units such as which covers both 2.4GHz and 5GHz to approximately 15 meters, the popular spy camera jammer which covers 2.4GHz WiFi only to approximately 20 meters, or the extremely powerful which covers both, up to 250 meters.

There are some variations in the coverage area depending upon local signal strength, physical environment, etc. Where the signal is weaker, the coverage is greater, and vice versa.

How Far Should WiFi Reach?

Variations in the WiFi signal range can occur due to factors like the frequency range, signal strength, and the number of walls or obstacles that obstruct the signal between your jamming device and the router.


For your devices, the 2.4 GHz frequency band ensures broader coverage, albeit at a slower speed. In contrast, the 5 GHz frequency band offers faster speeds but has a narrower range, enabling your network to perform at its best.

Typically, a typical WiFi router has a coverage range of around 100 feet indoors and up to 300 feet outdoors in open spaces. However, the presence of other devices or materials can cause interference, resulting in a significant decrease in this range.

Signal Disturbances and Interference

The WiFi signal serves as the bridge connecting your devices to the internet, utilizing a frequency range (2.4GHz or 5GHz) that propagates through the air. Opting for newer equipment that supports the 5 GHz frequency band is advantageous due to the shorter range of signals in this band, reducing the likelihood of interference from other networks compared to older equipment operating on the 2.4 GHz band.


The material that poses the most significant obstacle to your WiFi signal is metal. With its exceptional electrical conductivity, metal can reflect WiFi signals, leading to buffering problems during streaming or videoconferencing, delays in gaming, and frustratingly slow loading times.

Walls (Concrete & Brick)

The capacity of walls to hinder WiFi signals is determined by multiple factors, including the composition and thickness of the wall material.

When it comes to WiFi signal penetration, concrete and brick walls present a challenge. However, concrete walls are more proficient at blocking WiFi signals than brick walls due to their higher density and thicker mass.

Windows, Glass & Mirrors

It's generally not recommended to place your router next to a window or a mirror, either. WiFi signals can't pass through windows, glass, and mirrors because these materials contain a thin layer of metal that reflects the radio waves back instead of allowing them to pass through.

An updated warning has been issued for those who employ wireless security cameras, such as "Ring," as a means of home protection.

Despite owning a Ring camera, a woman from Detroit was unable to capture the theft of her car from the front of her house. An expert in the area suggests that this is indicative of the growing technological expertise among criminals.

In a recent incident, the woman claimed that her car was stolen from her driveway. Upon examining the footage from her Ring camera, she noticed a notable absence of recorded hours.

In the opinion of Chris Burns, the owner of Techie Gurus, security cameras that utilize WiFi for recording are more focused on providing convenience rather than ensuring robust security. This is because WiFi signals can be easily disrupted, thereby preventing the camera from effectively capturing footage of individuals near your residence. Unfortunately, criminals have become aware of this vulnerability.

jammer phone

According to Burns, it is a misconception to view wireless as a reliable security measure. He highlighted the fact that wireless signals can be easily wifi jammer or blocked.

This gadget can be utilized by the wrongdoers as a WiFi jamming device or a deauther, with a compact design resembling that of an Apple Watch.

By standing in close proximity, a deauther can overpower a WiFi system, compelling the WiFi camera to cease its recording. This accessory is available at a relatively affordable price, typically ranging from $10 to $50. On the other hand, a jammer comes at a significantly higher cost, with prices ranging from $150 to $1,000.

The use of signal jammer, which are also highly illegal, presents a greater difficulty in locating them. However, a jammer with significant power can effortlessly disable WiFi security cameras on an entire street with a single button press.

In a statement, a spokesperson from Ring acknowledged that the performance of Ring devices can be impacted by WiFi signal interference, similar to other wifi-enabled devices. To resolve any connectivity issues, customers are urged to get in touch with Ring Customer Support.

How can customers protect themselves?

To achieve utmost security, Burns stressed the importance of a hard-wired connection, preferably through an ethernet cable or a similar medium.

The problem, although known to Ring, is considered to be infrequent, as stated by their spokesperson.

Burns pointed out that with the decreasing cost of technology, the demand for jammers is likely to grow, emphasizing the significance of keeping people fully aware and informed.

The proliferation of FPV drones has brought a flood of cheap wireless video tech. After flying and crashing a cheap FPV drone for a bit, [GreatScott] decided to try his hand at building his own video transmitter, which turned out to be a lot harder than expected.

jammer wifi


While digital technology has caught up to the FPV world, a lot of systems still use analog video, especially for drone racing. The video quality isn't great, but it has the advantage of very low latency. The technology is very similar to the old analog TV broadcasts, but mainly uses the 5.8 GHz license-free bands. It is essentially analog video signal, frequency modulated onto a 5.8 GHz carrier signal transmitted through an appropriately sized antenna.

After a brief failed experiment with a simple circuit built from discrete components, [GreatScott] turned his attention to voltage-controlled oscillators (VCO). He bought a couple of 5.8 GHz VCOs from Aliexpress, and created and used a simple opamp circuit to boost the FPV camera video signal to the required input level for the VCO. This failed to produce any identifiable image on his video receiver goggles. In an attempt to confirm that the VCOs produced the desired frequency, he ordered a similar 2.4 GHz VCOs and built a short range (20 cm) WiFi signal jammers. With a signal generator to create a simple input signal, and confirmed that it interfered with his laptop's WiFi connection.

After more experimentation with other VCOs, the closest [GreatScott] came to success was a barely identifiable image transmitted using a Maxim 2.4 GHz VCO.

Building RF circuits that interfere with the legitimate signal around you, or broadcasting out of band, is generally not a great idea, and could earn you an unpleasant visit from the authorities.

One thing that has always peeved me off is when people are driving around staring at their phones. And then they get mad at me for smashing my horn when they almost hit me or someone else. Then they go right back to staring at their phone again... so i smash my horn again.

But the thought has crossed my mind more than once of being able to smash a button and silently disconnect their phones rather than having my life and property put in peril. Makes me smile, but I would get in more legal trouble than they would for smashing into someone with their vehicle "on accident" when in fact their neglect and inability to focus on operating a machine is the real fault. In my experience, i have been in several accidents due to neglectful drivers and others not following proper use of the road, they get no legal penalty and I end up having to pay the cost due to the fact that insurance is a scam that never pays out without a more expensive lawyer. But then again for those people who are responsible, jamming would likely have them pick up their phone to look at it when their hands free call or podcast or music stops, potentially causing more havock than a single irresponsible driver.

Only tangentially related, but makes me think about every time someone wrecked my car or almost wrecked my car anytime i read about frequency interuption/jamming.

I read a few of the news articles and it sounds like the thieves are jamming WiFi and the sensors. This prevents the system from even triggering. The thieves are walking around the homes without the glass break, door, and motion sensors going off it seems.

Not commonplace, but getting some exposure in the news recently - gangs of organized thieves in metro Detroit area are targeting upper scale homes for burglaries. They are purportedly using wifi jammer to circumvent alarms (like Ring).

What can millions of Ring (and customers from other wifi-dependent alarm companies) do about this? IS there a viable counter to these signal jammer? Maybe it's time to explore legacy, analog wired alarm solutions as backup instead of the reverse?

They're using a wifi jammer, according to this article. No obvious way to prevent this, so hardwired systems would be the only resistant option.

Most Wi-Fi jammers use disassociation flooding to kick the devices off the network. This attack is prevented with WPA3 which can use protected management frames. Unfortunately Ring still hasn't got around to adding WPA3 support to its devices. It was requested via their feature request process a long time ago, so I'm not overly hopeful they'll add it.

There are trade offs and risks with each security system. There's also different types of burglars from opportune amateurs to seasoned pros.

If you're concerned about this threat, there's a raft of solutions out there with high definition footage without any reliance on Wi-Fi or internet.

Whatever they're using for jamming must go beyond the WiFi frequencies to affect z-wave and whatever frequency Honeywell et al uses for their RF communications.

This makes sense because most alarm systems these days (even ADT/Brinx/etc) rely mostly on wireless sensors.

This is a huge vulnerability because it's pretty rare to find a security system that's been installed to use all hardwired sensors. To go hardwired you probably had to have it built-in as the house was built or did it while doing some major remodeling.

Cellular jammers are readily available. DSL, cable, or fiber are not jammable, but all devices need to be hardwired.

Zwave can be jammed just as easily as wifi. Cellular is great but if the door/window sensors are blocked and unable to report to the base station, the alarm won't think anything is wrong.

What I found when doing some simple research over the last couple of days is that different manufacturers use different frequencies for their devices so it might be a guessing game for the burglar, although my guess is that the professional burglars carry jammers for most of the common frequencies used by the big name brands like Ring, Simplisafe, Nest(ADT), etc.

To me it makes sense to have devices from different brands. Ring doorbell, ADT alarm, Wyze cameras, etc...

What's scary is that there are a bunch of videos on youtube demonstrating how easy it is to bypass these alarms AND with instructions telling you exactly how to do it and how to get the jammers.

Is this pervasive? If you watch the news, it's pretty evident thieves aren't concerned with cameras. They mask up and hood up and go. Be on alert, they have no fear.

Burglars can use wide-band jammers to jam all frequency bands : GSM, LTE, Wifi and Z-Wave. Some alarm systems are robust to such attacks (like Ajax Alarm System --

In short, the alarm hub must be hardwired with Ethernet to your router; And hub, router and modem on a battery backup. Then, only communications between sensors and hub can be jammed.

Then, alarm hub communicates frequently with sensors. If communication fails, it signals a jamming attack, notifying the user via hardwired Internet. With a working speaker on the hub, it can sound a siren and send a voice alert to the intruders.

SimpliSafe system is another system that offers some jamming protection, but lacks the Ethernet hardwired connection, so it must rely on a GSM/LTE link, which is still better than Wifi alone.

A recent caution has been issued for those who rely on wireless security cameras like "Ring" for safeguarding their residence.

In Detroit, a woman reported that her Ring camera failed to record the theft of her car from the front of her residence. An expert in the area suggests that this occurrence signifies the growing technological expertise of criminals.

The woman stated that her car was stolen from her driveway earlier this month. Upon reviewing the footage from her Ring camera, she noticed that there were missing hours.

The statement made by Chris Burns, the proprietor of Techie Gurus, highlights that security cameras relying on WiFi for recording purposes are primarily focused on convenience rather than security. This is attributed to the vulnerability of WiFi signals to interference, potentially leading to the camera's inability to effectively surveil the surroundings of your home, a concern that criminals are exploiting.

According to Burns, using wireless for security measures is a flawed approach. He pointed out that wireless signals can be easily interfered with or obstructed.

These individuals can employ this as a wifi jamming device, or a deauther, that could potentially be as compact as an Apple Watch.

By standing within close range, a deauther can overpower a WiFi system, compelling the WiFi camera to cease its recording operations. This accessory is available at a relatively affordable price, typically ranging from $10 to $50. On the other hand, a jammer comes at a significantly higher cost, with prices ranging from $150 to $1,000.

Due to their illegal nature, singal jammer are not easily accessible. Nevertheless, a strong camera jammer can effectively stop an entire street from being captured on WiFi security cameras by a mere push of a button.

In a statement, a representative from Ring highlighted the potential impact of WiFi signal interference on Ring device performance, similar to other wifi-enabled devices. Customers encountering connectivity issues are urged to seek help from Ring Customer Support.

How can customers protect themselves?

According to Burns, true security can only be achieved by utilizing hard-wired connections like ethernet.

The spokesperson representing Ring stated that they are mindful of the situation, highlighting its infrequency.

According to Burns, as technology becomes more affordable, the demand for jammers is expected to rise. Hence, it is imperative to ensure that people are adequately educated on this subject.

According to authorities, a gang of thieves has been outmaneuvering sophisticated devices in various locations across Los Angeles.

On March 4, the Los Angeles Police Department released a statement alerting the public to a group in Wilshire employing Wi-Fi jamming technology to neutralize surveillance cameras and alarm systems that are Wi-Fi-enabled.

The current wave of tech-savvy robberies in California is indicative of a larger-scale "smart" crime wave that is sweeping the nation. Similar alerts were issued by the police in Minnesota and Connecticut last year, warning residents about groups of thieves proficient in Wi-Fi jamming techniques. These incidents serve as just a glimpse into the multitude of similar cases.

signal jamming

According to KARE11, criminals can readily purchase Wi-Fi signal jammers jamming devices at a low cost, despite the Federal Communications Commission's ban on them. These devices do not directly disable other devices but rather overload the network they are connected to.

According to cybersecurity expert Mark Lanterman, these devices are designed to disrupt radio transmitters, causing traffic jams that prevent legitimate communication.


According to his advice, if you intend to employ a Wi-Fi camera for your front door, it might be worth considering the use of a hardline camera inside your home. Wired cameras that are connected via Ethernet cables do not rely on Wi-Fi networks and are immune to disruptions caused by a wifi jammer.

The Los Angeles police highly advises the use of hard wired burglary alarm systems.

According to Tom's Hardware, smart technology may play a role in both the problem and the solution. Officials suggest the use of timers or smart home devices to give the appearance of someone being at home while you are away. Additionally, some smart home technology can alert users of any interruptions in the signal or connection.

Tom's Hardware suggests connecting surveillance devices to your device for storing camera footage, rather than solely relying on a cloud storage system. By doing so, you can ensure that even during a Wi-Fi disruption, the footage will be saved and accessible.

Individuals are urged by the LAPD to stay cautious by locking their doors, asking neighbors to keep an eye on their surroundings while they are away, and informing law enforcement about any suspicious activity, particularly concerning vehicles with temporary or dealer plates.

Wilshire Park is located in Central Los Angeles.

The topic at hand pertains to wifi interference and devices that rely on wifi for transmitting data.

The discussed wifi interference does not impact cellular or sensor RF signals.

Wifi-enabled cameras and wifi communication for dual path signaling could be vulnerable. Certain third-party security systems rely solely on wifi, and they appear to occasionally substitute the term security system with that of a single doorbell camera.

Extended wifi disconnection would be identified as a dual path communication breakdown. The system utilizes RF jam detection for PowerG and traditional sensor frequencies, however, there is no mention of wifi interference.


wifi jammer and cellular jammers are both designed to block different signals that require jamming.

They manufacture combination devices that effectively disrupt both cellular and wifi signals within a single unit.

Criminals are becoming increasingly adept and employing more elaborate methods to carry out their illicit activities.

The news broadcasted footage of burglars entering a business located next to jewelry stores due to their vulnerability to break-ins. They were seen utilizing a sledgehammer to breach the drywall and gain access to the jewelry store.

It is important to emphasize that my intention is not to cause unnecessary alarm, but it is worth noting that thieves are increasingly going to extreme measures to break into properties.

It is my firm belief that alarm companies must confront this issue and proactively stay ahead of the changing trends.

The Glendale Police Department released a statement on Tuesday regarding the recent increase in residential burglaries that have occurred over the last few months, not only in Glendale but also throughout Southern California.

The GPD stated that suspects have been using technology in certain instances to carry out these crimes, including the use of Wi-Fi signal blockers or "jammers" to avoid being detected by home security alarms and cameras.

These devices emit signals that are inaudible to humans and effectively disrupt Wi-Fi signals and security systems, rendering them disconnected from the network and alarm systems disabled. A portable signal jammers, capable of blocking wireless communications within a 15-meter radius, exemplifies such a device.


GPD has stated that this technology causes interference with the signals transmitted by residential Wi-Fi systems, resulting in the interruption of conventional home security systems and cameras. Consequently, these security measures become incapable of notifying homeowners or law enforcement about the presence of intruders. The occurrence of such incidents has given rise to substantial apprehensions regarding the safety and security of our community.

The number of burglaries has been steadily declining according to the latest report from GPD. In December and January, there were 19 incidents each, followed by 18 in February. The most recent data shows that there have been eight burglaries so far in March.

So now that thief's are using WiFi jammers that apparently can be bought for $40, what is everyone turning to to protect your property?

8 Bands Jammer Device


News of break-ins these days show quite a few security camera captures, but in many of them the perpetrator is covering their face. So ultimately I'm not so sure how much security cameras (even wired ones that capture clear images) can really protect a property.

It appears even traditional alarm systems would be disabled by a signal blockers since all the sensors' signal would be blocked as well.

I have NEVER considered a WiFi connected device to be any sort of serious security device. For a serious security device, it needs to be wired (power and data), and the video recorded locally with serious backup power (no, a 15 minute UPS does not qualify). I do have what would likely be considered a Pro-sumer level video camera system, with hours of backup power.

With that said, I have over 40 Wyze cameras, and I do use them regularly as they are quite a bit less expensive than my wired system, and the software is more convenient for a quick look remotely.

Two of the most common attacks are a simple broadband signal generator and a specific WiFi De-Authentication. In the case of the first, the jammer simply broadcasts a strong enough signal that the intended signals are covered in noise. An audio example would be trying to talk back and forth with someone 100 feet away in an empty stadium. That would likely work fine, but now add 50,000 other people and there is so much noise that the person 100 feet away can not be heard. A broadband jammer is a quite simple device.

A De-Authentication attack is an smart device that to keep this simple, impersonates the WiFi client and sends a command to the WiFi access point telling it that the client is disconnecting. Note that WPA-3 prevents that by encrypting the management packets. However although the WPA-3 standard has been out for quite a few years, most IoT devices do not support it.

Both of these attacks happen between the WiFi client and access point, so a firewall or anti-virus never get involved.

The Morris County Police Department is warning residents about a new home invasion technique that involves jamming Wi-Fi signals, making it impossible for residents to call for help or access security cameras while thieves are inside the home.

Police say the technique was used by thieves in an unsuccessful burglary in Florham Park earlier this week.

According to a social media post by Florham Park Police Chief Joseph Orlando, authorities believe the suspect is part of a South American burglary ring that uses Wi-Fi jammers.

"While Wi-Fi jammers are nothing new to the criminal world, this is the first time we have seen or heard of them being used in Morris County," Orlando said. "The advancement in criminal technology used by these criminal gangs is alarming."

A resident of Lincoln Avenue in Florham Park was in his basement around 11:30 a.m. Monday when he heard a loud bang coming from the first floor, police said. He checked his home's security cameras and saw a man trying to gain entry to his home.

Soon after, the resident's camera system and cell phone lost service, indicating the suspect had used a Wi-Fi signal jammers to disable any Wi-Fi-enabled device, police said.

The suspect fled after realizing the resident was home, police said.

Still unable to use his cell phone to call for help because of the jammer, the resident ran out to the street to get help, police said. A pedestrian called 911.

Florham Park police arrived less than a minute later and searched for the suspect, authorities said. The Madison Police Department and Morris County Sheriff's Office also assisted in the search, but the man was not found.

Police said they suspected the man was part of a South American burglary ring that used Wi-Fi jammers, but they did not elaborate on any other connections between Monday's attempted burglary and the ring's previous crimes.

"These criminals are of South American descent and typically work in groups of three, park their getaway vehicles on adjacent streets, and utilize various pre-operative surveillance techniques to track their targets' patterns and behaviors to minimize the likelihood that they will commit thefts while residents are home," police said.

Police said gang members also used surveillance cameras (disguised as landscape plants to blend into the home's outdoor landscaping) to monitor movement in and out of homes before attempting to break in.

Police said the gang's surveillance cameras can be disguised in a variety of ways.

"They come in a variety of forms, including fake utility boxes, flower pots, tree stumps, rocks and boulders, and even those funny owls that move their heads, supposedly to repel critters," police said. "Basically, you know what's in your yard or front landscaping area and what doesn't belong to you."

Members of the South American burglary gang have committed burglaries across the country, including Baltimore, Los Angeles, Indiana and Florida. In April, the FBI warned of the presence of an international organized burglary ring in Indiana.

The FBI said the gangs typically target homes in affluent neighborhoods while residents are away and often steal high-end jewelry, accessories and cash. Officials said the gang members traveled to the United States to commit the thefts.

"While we are still investigating this incident, the only response strategy we can offer at this time is to install a surveillance camera system in your home and install a landline to combat Wi-Fi jammers," Florham Park police said. "In addition, regularly check your landscaping for any potential disguised surveillance devices and contact the police department immediately if you find such a device."

Officials are also asking Florham Park residents near Lincoln Avenue, Cathedral Avenue and Lockwood Road to check their surveillance systems between 11 a.m. and 12 p.m. Monday for signs of potential suspects or vehicles

Police said the suspect in Monday's suspected burglary attempt was a man wearing tan or beige pants, a dark shirt and a face mask.
