First, compared with analogue monitoring system, digital monitoring system has obvious advantages. As a high-tech product which applies computer digital video compression and transmission technology to image monitoring field. The working principle of digital monitoring equipment is that the computer transfers simulative video signal into digital information to achieve video information function of collection, browsing, transmission, storing and playback. Moreover, the computer can accept all kinds of alarm information, output relay control information, and automatically execute alarm linkage operation according to the procedure program beforehand. Digital monitoring system has a good man-machine interaction interface with its uniform management of video monitoring, pan-and-tilt control, image change detection, alerting signal input, relay control signal output, alarm linkage operation. You can find cheap wholesale of digital monitoring equipement.
Second, the intelligent management of monitoring system via computer makes alarm layout more reasonable. The computer makes security work systematical, which avoids any slips and makes prevention work safer and more deliberative, and more effective to prevent criminal based on full use of multi-media and combined with technology like real-time capture and video alarm.
At last, it can reduce protection intensity to adopt digital monitoring system. It seems the security work is simple; in fact, it is a complex and tough job with heavy responsibility. When adopting digital monitoring system, it improves security as well as reduces workload.
