ELECTRONIC APPARATUS DETECTION AND CONTROL SYSTEM, CONCERNED WITH DETECTING A CAMERA, A RECORDER, AND A WIRETAPPING APPARATUS

摘要

PURPOSE: An electronic apparatus detection and control system is provided to analyze harmonic components generated from a P-N contact of an electronic apparatus, and to perceive whether a passer has the electronic apparatus. CONSTITUTION: An electronic apparatus detection system(1) consists of a high frequency signal generator end(2) and a harmonic signal receiver end(3) for detecting a harmonic signal generated by a person who passes by the detection system(1). The high frequency signal generator end(2) consists of a high frequency signal generator and a transmission antenna. The harmonic signal receiver end(3) consists of a receiving antenna and a harmonic signal processor. A high frequency signal display(4) displays a detected signal, and decides whether the person has an electronic apparatus.
