Best RF Bug Detector in 2021

What is an RF bug detector?

An RF or electronic bug is commonly used for acquiring secret information. A bug is a combination of a radio transmitter and a microphone or video camera. The microphone or video camera listens to and records sensitive conversations while the radio transmitter sends that information out. RF detectors are able to ‘catch’ the transmitted signal.

Bugging can be performed through a variety of devices such as mobile phones, hidden cameras, Wi-Fi routers, and Bluetooth devices, etc. An RF bug detector can accurately sense these devices and protect your privacy to give you a more secure environment.
