A video surveillance system

Abstract

The invention discloses a high-confidentiality video monitoring system, which comprises a plurality of anti-theft video signal communication units and a monitoring terminal module, wherein each anti-theft video signal communication unit comprises a video signal acquisition and encryption module and a video signal decoding module; light emitted by a driving laser passes through a bi-optical feedback loop, an optical isolator, an optical fiber amplifier and an optical fiber coupler FC2, one path of the light enters the video signal acquisition and encryption module, and the other path enters a balance detector through a second response laser; and an optical signal is input into a first response laser of the video signal acquisition and encryption module through the video signal decoding module, and after the light signal passes through a first delay line, the light signal and a video signal collected by a network camera are loaded together to be transmitted to the balance detector of thevideo signal decoding module. According to the system, the collected video information is loaded on a chaotic signal for transmission, and the safety of video information transmission is guaranteed through two paths of synchronous chaotic information.

Description

technical field [0001] The invention relates to a video monitoring system, in particular to a high security video monitoring system. Background technique [0002] As an important part of the security system, video monitoring has developed into today's network video monitoring after analog monitoring and digital monitoring with the rapid development of modern computers, networks, image processing, and transmission technologies. The video surveillance system realizes the integration and linkage of video surveillance and conferences, and can manage remote devices flexibly and effectively. Video surveillance is characterized by intuition, accuracy, timeliness, and rich information content. Through the application of video recording, playback, linkage alarm, monitoring strategy formulation, and emergency command of remote monitoring objects, it can achieve dual functions of monitoring and communication, so as to fully meet the needs of traffic Remote monitoring and emergency com...
