Bug Detectors

Bug detectors can be used to tell if someone is listening in on your conversations or watching you with a hidden camera.  Bug detectors are small, electronic RF I (radio frequency)  scanners which work by detecting whether or not there is an RF (radio frequency) transmitter located in a room.  Some give an indication of the actual frequency, while others just indicate the strength of any frequency that they find.

You use these devices by walking around a room with the scanner in your hand.  If you get close to the a transmitter the device starts generating a tone, which gets louder as you get closer to the device.  The display will also indicate the presence of a signal.  This allows you to pinpoint the actual device and dispose of it.  For more information on bug detectors.
