Who knows security monitoring common faults and solutions?
It's OK to divide the equipment into cards. For example, the back of the surveillance system has a ripple of water
What's wrong with you?. If you don't know where the problem is, you can find it by substitution.The monitoring system is divided into three parts, the front end and back end transmission
Can first separate the monitoring system, 1 first check the front-end equipment, with engineering treasure to connect the camera, there is no ripple, not in the use of monitoring power supply project, treasure access surveillance video. If there is no front end, no problem. After processing the back end, insert the rear video line directly into the engineering treasure video, if not, that is the problem on the hard disk video recorder, if you have one. That's the transmission part. The transmission section can see whether the video lines have power jamming devices, powerful electric power, signal communication towers and so on. Some words can be wire principle interference source or install galvanized tube, reduce electromagnetic interference, or use video anti-interference device and so on.
