    一般來說,4路以下的監控系統採用獨立供電比較合適;4-16路的監控系統,若距離相當,建議選擇集中供電模式;16路以上的監控,可以採用多路集中供電結合,但前提是必須做好前期配置,其原因在於:

    1.系統維修時需要經常打開或關閉電源,這會導致啟動電流特別大,對電源造成很大的衝擊力,嚴重的會燒毀電源。

    2.當電源發生故障時,由於所有攝像機共用一台電源,這會導致整個閉路監控系統陷入癱瘓。

    3.當某台電源發生故障時,可將重要出入口的攝像機接到其他好的電源上,不至於影響整個系統的工作。

    不過具體怎樣選擇,還要視乎實際安裝環境及要求而定。

    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.
