System, Method, and Apparatus for Wireless Camera Detection

摘要

A system, method and apparatus for detecting wireless video cameras includes receiving radio waves in a radio frequency band and filtering and down-converting the radio waves into an intermediate frequency. The intermediate frequency is then filtered, amplified, and demodulated into an FM video signal. Then it is determined whether synchronization pulses exist within the FM video signal and if substantial synchronization pulses exist within the FM video signal the detection of a wireless video signal is signaled (e.g., making noise, vibrating, or illuminating).

主权项

1. A portable system for detecting wireless video cameras, the system comprising:
an enclosure; at least one video receiver, the at least one video receiver operating in a radio frequency band typically used for video transmission, the at least one video receiver housed within the enclosure; at least one antenna housed within the enclosure, each of the at least one antenna operatively coupled to a respective video receiver of the at least one video receivers; a sync detector operatively coupled to the output of each of the at least one video receiver, the sync detector signaling an output upon detection of synchronization signals at the output of any of the at least one video receiver, the sync detector housed within the enclosure; an indication device housed within the enclosure; and a processor operatively coupled to the output of the sync detector and coupled to the indication device such that, the processor determines if the portable system for detecting wireless video cameras is receiving a wireless video signal and, responsive to detecting, the processor initiates operation of the indication device, the processor housed within the enclosure.
