How to connect Haikang 12 core power cord?

1. First of all, it is "input": the input has three terminals, and the above figure is L, N and ground respectively from left to right. L corresponds to the fire line, n corresponds to the zero line, and three horizontal line icons correspond to the ground line. Three input terminals are commonly used 220V power lines.

2. The second is "output": the output has four terminals, namely two negative electrodes and two positive electrodes, the two negative electrodes are COM and COM respectively, or some power supplies are marked (COM 1 and COM2), and then the remaining two are positive electrodes +V and+V. ..

3. Finally, the live wire, the neutral wire and the ground wire are shared power lines, and the negative electrode and the positive electrode are the positive plate and the negative electrode of the surveillance camera. General 12V 10A monitoring power supply can supply 10 monitoring cameras. For example, if 10 surveillance cameras are to be connected, the negative poles of the power supply of 10 surveillance cameras are all connected to the negative poles. Similarly, the positive electrode is connected to the positive electrode. Although the positive and negative electrodes are only two terminals, they can be connected together if there are more cameras.
