Description

technical field

[0001] The invention relates to a monitoring device, in particular to an audio and video monitoring system based on optical fiber transmission. Background technique

[0002] Surveillance technology, as an indispensable security service in modern society, is currently widely used in many squares, shopping malls, stations, banks or underground parking lots, etc., so as to achieve multiple purposes such as anti-theft, recording, and traffic guidance. The traditional video surveillance system is an analog video surveillance system. The transmission of the signal collected by the camera mainly adopts analog coaxial cable, twisted pair, etc. Such transmission has some disadvantages:

[0003] (1) The transmission distance is short, and the farthest transmission distance does not exceed 1000 meters when using SYV75-9;

[0004] (2) The transmission signal is single, and the video, audio, and control signals must be transmitted in different lines;

[0005] (3) Using ...

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 Shown, a kind of audio-video monitoring system based on optical fiber transmission, comprises front-end camera 1, pickup 2, optical fiber transmission module, digital hard disk video recorder 5 and display 6, described front-end camera 1, pickup 2 are connected with the input of optical fiber transmission module respectively The output end of described optical fiber transmission module is connected with digital hard disk video recorder 5 and display 6 respectively; The audio-video signal that described front-end camera 1 and pickup 2 collects is transmitted to digital hard disk video recorder 5 and display respectively by optical fiber transmission module 6. The digital video recorder 5 stores the received signal, and the display 6 displays the received signal in real time.
