A recent viral news story emerged from Queens, New York, featuring a burglar skillfully gliding across the floor while clutching a mysterious device. Speculation surrounding the incident suggested that the device in question was a wifi jammer, utilized by the burglar to disrupt the home's wifi network and render the alarm system useless, thus evading detection.
Is this even possible? Yes, yes it is.
Typically, these jamming devices produce a signal that disrupts communication on the frequencies used by 3G, 4G, 5G, cordless, and wifi networks. Essentially, they affect all of these networks.
The presence of excessive noise disrupts the functioning of devices that rely on those frequencies, preventing them from operating normally. Consequently, even emergency networks utilized by first responders are affected, rendering such devices illegal. However, these illicit devices are manufactured and sold on the black market, and it is possible for individuals to construct their own. It is advisable to refrain from searching online for instructions on how to do so, as it may attract unwanted attention from surveillance authorities.
A jammer disrupts the frequencies utilized by our devices by generating its own noise, thereby preventing them from functioning. As these frequencies emanate from the signal blocker device, they have the potential to obstruct numerous devices, including those not intended by the user.
Upon discovering this information, do you believe it has the potential to disrupt your phones, alarm sensors, alarm base station, smart locks, and wifi cameras? Indeed, it is a possibility.
It is natural to have the question in mind, "Andy, my alarm system has a cellular backup in case the wifi connection fails. Will that still be effective?" Unfortunately, the answer is no. The sensors will lose their ability to communicate with the base station due to the interference caused by these jammers. It is important to remember that these jammers not only disrupt wifi signals but also block mobile spectrums, rendering your base station unable to make calls over wifi or a cellular network.
After learning about the nature and impact of these attacks, what measures can we take to prevent them? Have you recalled my advice against displaying the alarm company's sign in your yard for an extended period?
Revealing the security measures you employ at home can make you vulnerable to attacks from criminals who may exploit your defenses. Identifying companies that utilize the 2.4 GHz band is relatively easy.
When purchasing new smart home gadgets, search for those that are dual-band or operate on the 5 gigahertz frequency. I've come across information suggesting that WPA3 security can help thwart such attacks, but it's not entirely conclusive from my perspective as a beginner. Unfortunately, any wireless alarm system remains vulnerable to jammer attacks at the moment.
Opt for a traditional approach by installing a hardwired home alarm system that operates through a landline connection. As long as there are no wireless components involved, you should be all set.
Numerous companies, such as Ring, offer cameras equipped with local storage capabilities. In the event of a wifi outage or unavailability of cloud storage, these cameras rely on local storage to capture and store video clips. Although you may not receive notifications, you can conveniently access the footage by examining the SD card within the camera itself.
If you have made a significant investment in a wifi camera system, it is advisable to consider adding an inexpensive local storage camera to your home as a backup. This precaution ensures that even if you encounter a jammer or deauth attack, at least one camera will continue to capture footage. However, it is important to note that if the attackers identify the camera, they may attempt to destroy it and seize it.
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.
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.
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 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 TSJ-WiFi-5GH 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.
The range of the WiFi signal may differ due to various factors, such as the frequency range, signal strength, and the presence of walls or obstacles between your jamming device and the router.
The 2.4 GHz frequency band offers improved device coverage, albeit at a reduced speed. Conversely, the 5 GHz frequency band provides faster speeds but has a limited range, thereby optimizing your network's performance.
The range of a standard WiFi router typically extends up to 100 feet indoors and up to 300 feet outdoors in open spaces. Nevertheless, the presence of other devices or materials can cause interference, leading to a notable reduction in this range.
The WiFi signal enables the connection of your devices to the internet by 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 crucial 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.
Metal is the primary material that will significantly weaken your WiFi signal. As an exceptional conductor of electricity, it has the ability to bounce back WiFi signals, resulting in buffering while streaming or videoconferencing, delays during gaming, and irritatingly sluggish loading times.
The ability of walls to impede WiFi signals is contingent upon several factors, such as the composition and thickness of the wall material.
WiFi signals often face difficulties in penetrating concrete and brick walls. Among the two, concrete walls pose a greater challenge as they have a higher density and thicker mass, making them more effective at blocking WiFi signals compared to brick walls.
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.
Suspects involved in the break-in are employing cell-jamming technology as a means to evade detection by surveillance cameras.
CMPD has reported that burglars have managed to outsmart surveillance cameras during certain instances of home break-ins by utilizing advanced technology.
Cell-jamming, also known as signal interference, occurs when an individual utilizes a device to disrupt radio or wireless transmissions.
The Federal Communications Commission has stated that deliberately using a phone-jammer, GPS blocker, or any other signal jamming device to obstruct, disrupt, or interfere with authorized radio communications is considered a breach of federal law. It is important to note that there are no exceptions for using such devices within a business, classroom, residence, or vehicle.
Cellular jamming may be initiated by a device positioned at a distance of around 30 feet from the intended target, or alternatively, by home cameras.
Footage obtained from a residential area in south Charlotte exhibits an individual surreptitiously moving through a backyard during nighttime. However, it is important to note that not all occurrences have been recorded on video.
John Shocknesse, VP of Customer Operations for CPI Security, stated that people will always try to disrupt wireless communication, regardless of whether it is on Wi-Fi or any other network.
Within seconds, a person can be captured on camera, but with the use of cell-jamming technology, a single switch or button press is all it takes for that individual to vanish without a trace.
CMPD has reported that this problem has occurred during several incidents of home break-ins in the southern region of Charlotte.
Shocknesse emphasized that there has been no evidence of such activity. They are actively acknowledging this issue and striving to acquire the most advanced and cutting-edge technology, which holds the highest significance for them.
Shocknesse stated that the lack of encryption is noticeable in older wireless devices.
According to him, the latest security and surveillance systems incorporate advanced technology with encryption, resulting in enhanced security measures.
Shocknesse emphasized the significance of having cameras and onboard recording, stating that it cannot be stressed enough. The cameras are equipped with memory devices, ensuring that even in the event of a problem, the footage of the incident is recorded and can be presented to the police department.
In addition to his previous suggestion, he recommended that the most effective measures to avoid cell-jamming are to utilize modern technology with encryption and to opt for a wired device instead of Wi-Fi.
To effectively prevent home break-ins, it is advisable to adhere to basic guidelines such as ensuring proper illumination, activating alarm systems, and keeping bushes trimmed to a maximum height of three feet.
