How To Jam Wireless Security Cameras
There are three ways to jam the wireless signal from a CCTV system.
- The power supply must be cut
- Blocking radio frequency signals
- Deauthentication attack/ Locking WiFi signal
Hacking Wireless Security Cameras By Cutting Off Power
You can only use a plug-in wireless device to accomplish the task. These cameras can be used with both indoor standalone WiFi cameras and wireless NVR systems.
You can also disable the camera’s power, just like you did with analog CCTV or wired PoE. Simply cut the cable and plug it into the socket. This will turn off the device and stop it from recording any footage.
If the backup battery is present, you can cut the cable to turn off the main power supply. The camera will continue to record everything within its range and be active.
By Blocking Radio Signals, Jam Wireless Security Systems
This trick involves creating a wall between the camera’s control panel and the control panel so that the signal doesn’t cross. The trick is to stop the cameras from communicating with Homebase. For expandable P2P systems such as Heimvision HM241A, the band barrier prevents the cameras from reaching the NVR.
However, a wireless signal cannot interfere with another device operating at the same radiofrequency. If the jamming signal is to block or overpower the camera’s signal, it must be stronger. You must be aware of the frequency at which your wireless security camera system operates and have the appropriate equipment to jam it.
Nevertheless, many consumer electronics operate at 433MHz and 2.4GHz. This frequency is susceptible to interference from many interference generators. Other RF devices we use every day in our house. These devices include garage door openers, car remotes, two-way radios, and light dimmers.
You can choose from various frequencies for a walkie-talkie, such as 433MHz. The device transmits at a high power level, so the NVR or Homebase control panel might not be able to detect cameras with a lower output.
Your wireless CCTV system should still function if the interference generator/jammer is weaker than its transmission band.

Deauthentication Attacks Are Used To Jam Wireless Security Cameras.
This hack will not work if your security camera system uses a point-to-point connection. The de-authentication attack cuts off the communication between the router’s wireless and connected devices.
Although it is sometimes referred to as a software bug, it is actually an “internet protocol” which tricks the router into disabling connected devices. This is something that people use in real life, such as when they notice that unauthorized devices are stealing their WiFi.
This method can cause your wireless network to be compromised if a burglar initiates it. A broken camera is your best bet – it could compromise your privacy.
Is It Illegal To Jam Security Cameras?
Only criminal intent can be used for jamming security cameras. If you are “doing” criminal intention, it means that you are interfering with your company’s security system to gain access to the vault. When you “prevent” a criminal intent, it’s when you disable the hidden security cameras of AirBNB to spy on your activities.
Burglars can also drain batteries of battery-powered security cameras and other security devices (like Ring’s doorbell).
However, any signal jamming device is prohibited from being used or sold in the United States under federal law. Interferences with authorized radio communications are not permitted, no matter what purpose they may serve. In limited cases, local enforcement agencies can be exempted if they have the applicable statutes.
Signal jamming is prohibited by law because interference can affect security cameras and nearby radio signals. This applies to all wireless devices that we use daily, including police radar and GPS.
However, wireless signal jammers can still be obtained. Even a simple handheld radio can be dangerous if it uses the same frequency as your CCTV. We use wireless controllers on our gates, garage doors, and even cars, subject to the same rules.
How Do I Know If My Security Camera is Jammed?
Unfortunately, this is not always the case. Most consumer systems don’t have the advanced algorithm to detect signal interference. Your camera will simply stop recording or lose internet connection. Jamming is not an excuse for losing an internet connection or stopping recording. This could also be a problem with your CCTV company.
Monitoring the noise level of security cameras can be a great way to detect an interference generator. In this instance, the noise is not an audible sound but rather the strength of an external signal from a wireless device. It is usually expressed in decibel-milliwatts, or simply as dBm and can be measured from 0 to 100.
The reader’s number indicates the level of noise interference. A negative 70 dBm signal suggests an area with more signal interference than a positive 100 dBm. If a signal jammer is located near your wireless cameras, noise levels will be closer to 0.
Signal interferences can also be caused by many household electronics emitting radio and microwave frequencies. It is not always able to detect active jammers.
Dedicated monitoring devices are the only way to be sure that you can detect signal interferences and outside attacks. Fingbox by Fing or xFi from Xfinity is two examples. They keep an eye on the network and all connected devices.

How To Protect Security Cameras From Being Jammed
Now you know how to jam your home security systems. What can you do to prevent being a victim of CCTV interference?
The solution to this problem is simple: find the three methods of jamming the signal. This is how it works:
Cut Off Power Supply – Cover The Wires
If the intruder doesn’t know where he should start, he can’t shut off the power supply. You should hide security camera wires as best you can and ensure that devices are out of reach. A battery-operated system is also possible, which means there are no wires to worry about and can be easily hidden from the surrounding.
Blocking Radio Frequency Signals – Bypass the Jamming Device
Signal jammers can be difficult to jam. Although they can be detected, their transmit signal is more vital than most consumer security cameras. Hybrid security cameras and wired security cameras are the best way to defeat intruders without using a jammer.
This does not refer to the hybrid DVR with analog and PoE technology but rather to a wireless camera that supports frequency-hopping. This technique uses a unique code that allows transmitting and receiving devices to change frequencies if there is a stronger signal.
The jammer will not be able to intercept the frequency switch, which is often done quickly.
It’s important to remember that an intruder can’t jam your security camera if it doesn’t have the operating frequency. Avoid installing security signs with branded logos that reveal the manufacturer and model of equipment.
The internet is the most popular source of information, and a motivated burglar can find every detail about your CCTV by simply going online.
Deauthentication Attack – Use Stronger Network Encryption.
Protecting your wireless connection with WPA2 and WPA3 encryption is best to prevent de-authentication attacks. You should also give your WiFi signal an extended and stronger password. This password should include letters, symbols, numbers, and other characters that are difficult to guess.
Why Would Someone Jam Wireless Security Cameras?
Anyone who attempts to jam wireless security cameras is generally guilty. Jamming wireless security cameras is illegal, no matter what the intent. This includes selling or buying equipment that advertises jamming.
Can you jam a wireless security camera without getting in trouble? There is one gray area: if your neighbor has security cameras pointed at your property, this could be a problem. A wireless jammer can be used to block access to security cameras.
Technically, you would be guilty of a crime if a jammer was used to cover up the situation. Talk to your neighbor to discuss your concerns. You can also complain to your local HOA.

What If It Happens to Me?
It is technically possible to jam wireless security cameras. Anyone with the ability to jam a wireless security camera could target you. Remember that burglaries are often crimes of opportunity. An intruder will most likely have spent considerable time planning to hack your security system.
It is possible to achieve this scenario, but it is not impossible. An intruder who can enter a home without a security system won’t spend the money or time to learn about it.
