![]() ![]() As mentioned prior, it is possible to use a type of jamming in business or institutionally, but must be done following specific state and federal laws. Doing so against a person without their knowledge and in the majority of cases, in general, will violate the Communications Act of 1934. In short, no, using a signal jamming device is illegal in the United States of America as per the Federal Communications Commission. Most cell phone jammers may block a wireless network from reaching a phone, but when that happens, the phone will generally switch to what is next available and make most signal jammers useless in that regard. Not only that, but modern phones can run off of more than one signal. Therefore, what is more likely than both your cellular and Wi-Fi being affected by a single jammer is a specific part of your security system being temporarily disabled for as long as the crime occurs.Īn example of this can be your best home security camera with a 130-degree field of view and a live feed being blocked from connecting to your Wi-Fi network if it runs off of Wi-Fi or any given smart doorbell, like the Arlo video doorbell, being temporarily disabled. Moreover, commercially available signal jammers are limited by design to affect a short finite area. ![]() This is because jamming a cellular signal and Wi-Fi signal is done differently by design. ![]() However, such devices do not necessarily affect cellular phones and devices that run specifically on a Wi-Fi signal. There are cell phone jammers that can affect Wi-Fi signals and overall systems. A method to prevent this sort of invasion of privacy by a malicious entity can thereby be the use of more traditional means or to use hardwire systems that do not run off of Wi-Fi signals. These devices do not just block wireless security cameras, but also mechanisms meant to make life easier like smart locks and smart doorbells among others. However, while signal jammers can be used to detect and disable monitoring equipment, criminals can use them to disable an indoor or outdoor security camera that is connected to a Wi-Fi network.
