Signal Jammer Tech

Thieves allegedly used signal jammer to fool San Jose man's Nest security camera

SAN JOSE, Calif. (KGO) -- This enigma unfolds in a manner reminiscent of numerous others, occurring during the late hours of the night.

The story commenced on the front porch of Jim Grubb's residence in San Jose, where the barking of his dog roused him from sleep.

He states that they awoke, descended the stairs, discovered the front door slightly open, and remarked to themselves, "It appears we must have left the door ajar last night."

The following morning, new evidence emerged. Grubb discovered that several items were missing, including a laptop and a drone.

He stated, "I accessed the Nest video camera positioned at our front door. The intruder was present in the front yard; the footage revealed a flashlight, and at times, his beanie cap was visible."

He continues by stating, "...and as I observe the video, I begin to notice these gaps within it, and I find that there are numerous gaps present."

There are portions of the video where we could potentially discern the thief's face.

Jim reached out to Nest customer support and was informed that the video doorbell had been communicating with the router without any interference prior to the incident.

He expressed his disbelief, stating, "I was astonished by this revelation. Consequently, I began conducting some research and discovered that it is possible to purchase a small microcontroller. This device can effectively de-authorize clients connected to your Wi-Fi network, thereby creating interference."

The items are priced at $7 each. For a total of $50, Grubb discovered a wrist model that provides enhanced precision in control. Although Grubb lacks concrete evidence, he is concerned that thieves might be interfering with Wi-Fi signals.

Google has expressed uncertainty regarding the situation, stating to 7 On Your Side: "Google Nest is dedicated to ensuring the privacy and security of our customers. We are currently aware of an isolated issue with the Nest Hello Doorbell, and our team is thoroughly investigating... there is no indication that the device was intentionally compromised."

Tristan Perry, a technology blogger hailing from Wales, has been examining this matter for some time and asserts that it is not particularly surprising.

It is widely recognized that Wi-Fi can encounter various problems, such as difficulties with mobile devices, interruptions during Zoom calls, or pauses in Netflix streaming, as stated in an interview with 7 On Your Side.

The rise of high-tech burglary techniques poses a significant challenge to conventional security measures, including cameras and alarm systems. Thieves have begun to employ strategies that interfere with Wi-Fi signals, thereby undermining the effectiveness of these protective devices. Police recommend that residents adopt various precautions to mitigate the risk of theft.

The majority of modern households utilize Wi-Fi signals to support their security system burglar alarms and surveillance tools, which encompass doorbell cameras.

Police advise residents to replace their Wi-Fi surveillance systems with wired connections. They recommend reaching out to network providers or electricians to facilitate the connection of the burglar alarm system to the router using cables. This strategy negates the need for Wi-Fi, thus preventing the interference of Wi-Fi jammers.

The FCC emphasizes to consumers that should they encounter any interruptions in their home Wi-Fi, they should immediately get in touch with their internet provider. This will help ascertain whether the problem is due to a malfunctioning device or if it is being compromised by a signal jammers.

VERMILIAN PARISH, La. ( KLFY ) — Authorities are asking for the public’s help in identifying a man who posed as a cable installer and attempted to break into a Vermilion Parish home.

The Vermilion Parish Sheriff’s Office says a man (pictured below) driving a white SUV attempted to break into a home on Red Rose Lane near Louisiana Highway 338 on Tuesday. Officers say he posed as a cable or security camera installer and used a suspected Wi-Fi jammer while trying to pick the front door lock.

Anyone with information about this incident is asked to contact Sheriff Chad Touchet at 337-898-4403.

9 burglaries in Minnesota suspected of disabling cameras by jamming Wi-Fi

- As technology becomes cheaper and more accessible, smart security systems become vulnerable

An analysis of news reports on burglaries involving Wi-Fi jammers reveals considerable prior evidence of such incidents. In January 2020, a post on the Ring community recounted an event where a wireless doorbell from the company failed to detect a porch thief as a result of a Wi-Fi deauthentication attack. Reports of burglars employing Wi-Fi jamming tactics were also prevalent in 2021, 2022, and 2023, with an observable increase in the number of such reports over time.

Ring has been noted as a significant contributor to the video doorbell sector, which seeks to mitigate numerous home security concerns. However, it is essential to acknowledge that other wireless smart home security solutions, such as those from Blink (Amazon) and Nest (Google), are similarly vulnerable to wireless signal disruptions. Alarmingly, by 2024, the capability to jam Wi-Fi signals is projected to become quite simple for would-be thieves. Jammers can be obtained online with ease, with costs varying from $40 to $1,000. Although the use of jammer device is illegal in the United States, they can still be found readily available on the internet.

For anyone curious about the performance of a wireless component home security system, several tips can be helpful. To begin with, connect a device that provides a wired option and facilitates local storage of video footage. Additionally, consider employing smart home technology to create the appearance of activity within your home. It may also be beneficial to verify whether your system can alert you in case of a lost signal or connection, and to experiment with these settings.

Authorities in Edina, Minnesota, have linked a serial burglar to the use of a Wi-Fi jammer, which was allegedly employed to disrupt security cameras before the theft of valuables from victims. Minnesota is not commonly associated with cutting-edge technology, so it may not be unexpected that there have been reports of Wi-Fi jammers-related burglaries in the U.S. over recent years. This highlights the fact that even those engaged in criminal activities are leveraging technology, underscoring the need for homeowners to consider security enhancements.

The police department in Edina suspects that a series of nine home burglaries within the last six months were carried out with the assistance of Wi-Fi jammers, which likely hindered investigators from retrieving video evidence related to the crimes.

The thieves’ modus operandi is believed to be:

• Homes in affluent areas


• The thieves carefully monitor the homes


• The thieves avoid confrontation, so appear to wait until the homes are empty


• The thieves deploy Wi-Fi jammers when the homes are empty

Jammers are designed to confuse wireless devices rather than to block signals outright. They usually do not succeed in transmitting real traffic because they overload the wireless communication channels.

At the time of their launch, cell phone zappers offered consumers few alternatives. They were predominantly oversized and unwieldy, posing difficulties for portability since they were larger than standard briefcases.

A man sought in relation to multiple home invasions in Queens, New York, was caught on a home security camera while trying to use a Wi-Fi jammer to obstruct the signal of a Wi-Fi-enabled security camera. The signal, however, was reestablished, allowing the camera to document his actions.

The suspect reportedly entered homes during the day, taking valuable items such as cash, jewelry, and luxury possessions, while ransacking the interiors. It was ambiguous whether the police were investigating a single suspect or multiple individuals who might be working in collaboration.

As reported by ABC 7 NY, it appears that the homeowners are often not present at the time the suspect arrives, which tends to happen just as they are leaving. Since July 24, New York police have confirmed that at least five homes have experienced break-ins under comparable circumstances.

In a recent incident, the residence of Imran Ahmed in Queens Village was breached during a break-in.

The security camera footage, which is Wi-Fi-enabled, was unable to be disrupted during parts of a home invasion. The video depicted a troubling sight of a man, concealed by various pieces of fabric, slithering across the floor. He was seen maneuvering a backpack and a black box, thought to be a Wi-Fi signal jammers. Nevertheless, his attempt to disable the camera was unsuccessful, as it continued to transmit signals and recorded his actions while he was in the residence.

Ahmed indicated that they were alerted at about 2:30 regarding the disruption of their Wi-Fi service. He noted that initially, he "didn't pay it much attention."

Within the video, a man is seen moving up the stairs, and when he descends, he expresses a sound akin to, "Tony, Tony, Tony, Tony."

Ahmed indicated that they were located only two blocks from the police precinct. He noted that having an event of this nature transpire is very unsettling.

The police are currently investigating a residence where $30,000 in jewelry was taken, along with a Louis Vuitton handbag worth $8,000.

The Internet is an extremely powerful tool that provides endless possibilities for work and play, with access to a wide range of information in just a few clicks. However, it also poses significant risks to privacy, security, and authority, both in professional and private settings.

It is a common reality that WiFi networks are easily misused. To combat these issues, using a WiFi blocker may be a solution. Whether you want to regain control of your family life, workplace, or protect your children, a Wi-Fi blocker can give you peace of mind.

Key Reasons You Absolutely Need a WiFi Blocker

1. A Wi-Fi blocker is an effective way to prevent students from cheating on classroom exams. By blocking Internet access, students cannot search for answers on their phones or access online resources. For laptop-based exams, you can ensure the integrity of the exam by having students download required documents before enabling the Wi-Fi blocker.


2. A Wi-Fi blocker can also serve as a form of parental control, allowing you to regulate Internet access for unruly children. If your children are using the Internet late at night or accessing inappropriate content, you can control their Internet usage when necessary. While some tech-savvy kids try to reactivate routers when left unsupervised, you can use a Wi-Fi blocker to maintain control over internet access.


3. Wi-Fi blockers are often used to prevent unknown and unwanted devices from transmitting data to malicious actors. Surveillance devices such as hidden cameras and microphones may be found in certain locations such as hotels, locker rooms, and Airbnb rentals. While some may have legitimate security purposes, others violate your privacy by recording your activities.


4. By using a Wi-Fi blocker, you can prevent surveillance devices from transmitting these recordings over the internet, thus protecting your privacy. Additionally, Wi-Fi blockers help prevent alarming activities such as webcam hacking, where someone gains unauthorized access to your laptop's camera and can remotely monitor your behavior.

Buying a WiFi Jammer

Before buying a WiFi jammer, it is important to evaluate the performance of your WiFi router. Different router models offer different levels of control and settings.

The general rule is to choose a WiFi jammer that can pinpoint the frequency on which your WiFi router communicates with your devices. To achieve this, you should identify the specific channels that your router supports and buy a signal jammer that can block at least one of those channels.

For example, if your WiFi router can be manually set to work only on the 2.4 GHz band, a simple jammer that blocks the 2.4 GHz frequency will be enough. However, if you don't have control over the channels of your WiFi router, you'll need to invest in an advanced WiFi blocker.

If you plan to use your WiFi blocker in different locations outside of your home, the process becomes more unpredictable. It may not always be possible to determine the performance of wireless routers in different locations. In this case, you can either equip yourself with a router that covers the most common channel options or invest in an advanced Wi-Fi blocker that can cover a wider frequency range.

Different types of WiFi jammers:

• Portable jammers: These compact devices are easy to carry and can fit in your pocket. They are suitable for personal use and offer limited protection.


• Larger models: Some WiFi jammers require a wired connection and offer stronger blocking capabilities. They are usually used in fixed locations and can cover larger areas.


• Frequency and range: WiFi operates on two main frequencies: 2.4 GHz and 5 GHz. Most jammers focus on blocking the popular 2.4GHz frequency. But for full protection, it is recommended to choose a model that covers both frequencies. Wi-Fi jammers vary in range, from short-range jammers with a range of 15 to 20 meters to more powerful models with a range of up to 250 meters.

WiFi and Bluetooth Jammer Selection

Our Bluetooth and WiFi Jammers are for Sale in Several Models

Picking the right WiFi or Bluetooth blocker is not as difficult as it might seem.

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.

The next important consideration is the size of the coverage area needed for your application. We offer units such as the 5GHz 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 WiFi-5G 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.

If you need additional assistance in choosing the correct model please contact us and our staff is happy to help you choose the correct jammer
for your needs.

The fatal explosions linked to the use of pagers and walkie-talkies by Hezbollah in Lebanon have prompted a thorough investigation into the origins of these related devices. This examination indicates that the market for these obsolete technologies is significantly unclear, and buyers often lack substantial information about the products they purchase.

The attack on pagers and walkie-talkies carried out by Lebanese Hezbollah, leading to the loss of 37 lives and around 3,000 injuries, highlights the complexities involved in determining which link in the chain failed.

Taiwan's Golden Apollo has charged a European company with licensing its pager brand, which has prompted investigations into the provenance of related products in Hungary, Bulgaria, Norway, and Romania.wifi jammer

How massive attacks took place simultaneously, injuring thousands

Time and place of the incident

At 3:45 p.m. local time on Tuesday, an explosion was reported in Beirut, the capital of Lebanon, with impacts felt in various other parts of the nation.

Eyewitnesses described the sight of smoke billowing from the pockets of individuals, along with auditory phenomena reminiscent of minor explosions similar to fireworks and gunshots.

Video evidence from surveillance appears to depict an explosion taking place within the pocket of a man who is standing at the cash register of a store.

Reuters has indicated that the explosions lasted for around one hour after the first detonation.

In the aftermath, a significant number of injured persons rushed to hospitals across Lebanon, while observers reported scenes of chaos in multiple areas.

How do pagers explode?

It may be that a hacker attack resulted in the overheating and explosion of the pager's battery. Should this be true, it would mark an unprecedented event. The attack is initiated through signaling, a method of alphanumeric text messaging.

• Pagers can be modified to explode, typically by using them as radio communication devices to remotely trigger bombs.


• A pager is a device that receives radio signals and can receive wireless messages in a specific frequency band. An attacker could exploit this feature to control an explosive device.


• When the pager receives a specific signal, it can use internal circuitry to trigger a detonator connected to the explosive. This detonating device is usually a relay or switch that connects the explosive to the pager's power supply.

It is common for attackers to opt for frequency bands that provide broad coverage to ensure that pagers can effectively receive the signal. The application of signal jammers can interfere with wireless signals in designated frequency bands, preventing pagers from obtaining detonation signals.

Everyone knows what CCTV cameras are, so my question is: can I use some kind of wifijammer to keep this rude thing away from me?!

Do you want to deal with annoying CCTV cameras (and maybe even video cameras) that are making your life worse? Great! Then you need to use that kind of signal jamming device, which has a wide spectrum consisting of the frequency bands it jams. I'm talking about UHF and VHF jammers, especially this one.

You see, the UHF and VHF bands contain a lot of different frequencies, so they are able to jam a lot of different electronic devices, which is really great because this particular device can be very helpful to a lot of people and solve a lot of their problems. It can help you too.

The operating frequency of CCTV cameras is within the frequency range of this desktop signal jammer, so within the shielding range of this device all CCTV cameras, hidden or not, will be completely blocked and unable to transmit any video signals.

Use a jammer to block the air conditioning control at my neighbor's house?

My neighbor has told me about his new air conditioner. Is there any way to disable the remote command?

Different modern people actively use modern devices. It is not a wrong decision. At the same time, many people forget that they should not show what they bought. Your neighbors also forget about this.

You can use special control jammers for any air conditioner. Such devices are specially designed for this purpose. In addition, these blockers operate at different frequencies and provide a test for unknown signals. You can use the device not only to lock the remote control, but also to perform other tasks with it. Choose only profitable modern solutions.

I wonder if a special device can be used to block wireless mice. At work, almost everyone uses such devices. It's exciting to see the faces of employees when all devices are turned off. Would this be a bit dangerous? Would I be responsible for this? It's exciting to know the answer.

Wireless mice are controlled using unique low-frequency Bluetooth signals. It is completely possible to block them with the help of external devices. In the office, you can easily use a compact Bluetooth signal jammer. Such a device is ideal. It can be used almost anywhere, regardless of the location. At the same time, the radius of action covers enough space.

Using such devices may accidentally block Wi-Fi signals. This also applies to other devices working on the Bluetooth interface, which you should take into account. That's why you should be as careful as possible. WiFi networks are also quite dangerous and vulnerable to such attacks.

Your idea is not bad, but you are responsible for all possible consequences. You may get into a lot of trouble when dealing with other employees. You should also understand how wireless mechanisms work during hacking. A bluetooth jammer may be a good solution, but using this device is entirely your responsibility. We hope we can help you.
