Anti Spy Detector
Wireless spy devices (WSDs) are surveillance equipment, such as listening bugs or cameras, hidden in objects or covertly placed in rooms. Surveillance using WSDs is one of the main methods of recording conversations for both intelligence gathering as well as criminal charges. However, WSDs have also been abused for nefarious purposes, such as industrial espionage and blackmail. This paper is aimed at reviewing WSD technologies, in terms of types, energy sources and modes of operations. Methods used for detecting WSDs, focusing on radio frequency (RF) detectors, spectrum analysis and nonlinear junction detectors (NLJDs), are also be discussed. Keywords: Wireless spy devices (WSDs); active and passive WSDs; radio frequency (RF) detector; spectrum analysis; nonlinear junction detector (NLJD).
RADIO FREQUENCY DETECTOR
RF Detector. The RF Detector, like most bug detectors, detect radio frequency signals sent from listening devices such as electronic bugs hidden in objects, or covertly placed in rooms. This RF Detector is able to sweep a room or area for privacy invading bugs and warn you about active RF transmitters.
