In modern life, surveillance cameras have been installed in many places, and video surveillance has become an indispensable security device in daily life. Of course, the security monitoring system also has everybody's heart. The monitoring system will also fail. If the fault happens to be monitoring the critical moment, it will be too crying for tears. Of course, the more sad thing is that it will still be useless if it finds fault in the monitoring system and it does not work for a long time. It's a real urge to hit a wall. Chengdu Wanquan electronics is aimed at the problem of no image in the security monitoring system, and how to check the method to share with you, so that you can no longer panic when the security monitoring system has no image.
For the security monitoring system without image problems, first check the connection of the monitoring host. Most of the reasons for monitoring failure are caused by power failure or signal failure. Therefore, when checking, it should first check the connection of the lines, for example, whether the coaxial cable of switching host to the monitor has occurred virtual connection or obvious breakage; whether the corresponding output port of the microcomputer switching host has not been inserted or failed, and whether the multi-function monitor has not chosen the correct browsing format and so on. Though simple, they are likely to be the culprit of causing no monitor.
