It can sense the presence of a 1-mW transmitter at 20 feet. which is sensitive enough to detect the tiniest bug. As you bring the rf detector closer to the bug, more and more segments of its LED bar-graph display light, which aids in direction finding. The front end has a two-stage wideband rf amplifier, and a forward-biased hot-carrier diode for a detector.After detection, the signal is filtered and fed to IC1, an LM3915N bar-graph driver having a logarithmic output. Each successive LED segment represents a 3-dB step.In short, A bug detector is a tool used by professional counter surveillance experts such as QCC Interscan, to detect hidden audio and video pickups and transmitters.If you are concerned that your office home or vehicle has been bugged, call us (from a secure location) and let the bug detector experts help ensure your privacy against electronic eavesdropping.
