The RF Wireless Signal Detector from KJB Security Products is a counter-surveillance device which locates hidden bugs that send digital transmissions using standards like Bluetooth, Wi-Fi, and analog signals broadcast at up to 12 GHz. The unit can detect a variety of conventional bugging devices including FM-modulated transmitters, digital transmitters, GSM bugs, etc. Using sound to detect transmitters, the unit can produce a loop-back effect with a microphone to pick up and transmit the beep. When a signal is detected the demodulation display will flash and the detector will sound depending on the type of transmission detected. The extra antenna allows the device to avoid interference from external sources in cities or near broadcasting towers.
