Build a device that silences Wi-Fi cameras

RF Clown is a project that demonstrates how to jam wireless signals from surveillance cameras using ESP32 and radio modules. While it is a technically interesting approach, there are legal and ethical considerations to consider when using it.

Wireless or Wi-Fi cameras are now almost everywhere, as wireless networks make it easy to install surveillance systems. This prompted a computer enthusiast who goes by the pseudonym [CiferTech] to develop the RF Clown device. It is essentially a tool that can jam the signals of these cameras in a certain area.

The device is based on the ESP32 microcontroller, has an OLED display and three control buttons. It is connected to three GT-24 Mini radio modules, which are connected to the antennas on the top of the device. Depending on the selected mode, the RF Clown can interfere with Bluetooth, BLE or Wi-Fi signals by emitting broadband noise.

Although the system is not particularly sophisticated, the use of multiple modules allows for jamming on multiple frequencies at once, increasing the likelihood of blocking legitimate transmissions. In a demonstration, activating RF Clown caused the Wi-Fi camera image to freeze as data packets no longer reached their destination.

It is important to note that interfering with foreign surveillance equipment may violate the law or ethical rules, so the project should be approached with caution. For the technically curious, the files are available at GitHubThe video is available below or at the link https://youtu.be/Jadzrg9bz40.
