*Instructions For Use
Dear friends:
Our this 12v 10a 8CH output power supply is composed of aluminum case, switching power supply, circuit board and UPS battery, super high power, split output, centralized power supply. When you use it, do not connect the positive and negative wires reversely. The neutral wire and live wire can be grounded casually, and the ground wire can be connected or not connected when necessary.
Precautions for adopting centralized power supply:
1) Match and set the camera power efficiency of the entire monitoring system.
When configuring the power supply, it is necessary to add the rated power of the cameras of the entire surveillance system and multiply by 1.3 times, and then add about 30% of the damage to configure.
2) Do not connect the remote camera and the close surveillance camera to the same power supply.
3) The line of the power cord should not be too thin, otherwise some cameras will not have enough power supply.
