Size and Range

As in other categories of electronic eavesdropping, recent technology has been utilized to build miniaturized RF transmitters the size of a pencil eraser. These devices will transmit radio signals anywhere from 100 feet to five miles and with the use of repeaters, reception range is even further. The availability of these small devices is rather astonishing with several manufacturers offering pre-concealed transmitters already packaged into such objects as smoke detectors, picture frames, clocks and ashtrays.

One of the smaller commercially manufactured transmitters is the size of an aspirin tablet, including microphone and battery, with a transmitting range of 1,000 feet. Several radio transmitters are available in prepackaged electrical lamps, power receptacles and clocks. These types have the advantage of a continuous power source, supplied directly to the transmitter, which permits a permanent installation. Eavesdropers could be listening many miles away,early detection of the device is essential.We at Listening -Device- Detection -Services have the most up to date equipment to ensure early detection of radio frequency attacks. ]]> http://www.listening-device-detection-services.co.uk/radio-frequency-attacks/feed/ 0
