How to choose independent power supply and centralized power supply Generally speaking, it is more appropriate to use independent power supply for the monitoring system of less than 4 channels; if the distance is 4-16, the centralized power supply mode is recommended; for the monitoring system of more than 16 channels, multi-channel centralized power supply can be used, but the premise The pre-configuration must be done, the reasons are: 1. It is necessary to turn on or off the power supply frequently during system maintenance. This will cause a particularly large starting current, which will cause a great impact on the power supply, and will seriously burn the power supply. 2. When the power supply fails, since all cameras share the same power supply, this will cause the entire closed-circuit monitoring system to be paralyzed. 3. When a certain power supply fails, you can connect the camera of the important entrance to other good power supply, so as not to affect the work of the entire system. However, how to choose depends on the actual installation environment and requirements. * * * * * * LIV is a professional data center to set up a company, with a group of professional team intimate attention to customer requirements, and provide quality services.
