The incorrect power supply of the surveillance camera can easily cause equipment failure and may cause damage to the equipment in the surveillance system.
There are roughly the following possibilities for the incorrect power supply of the surveillance camera:
1. The power supply line or power supply voltage and power are not enough (or the wire diameter of a certain power supply line is not enough, the voltage drop is too large, etc.), which causes the surveillance camera to frequently drop the line, the infrared light or the white light cannot start normally, and the camera light cannot be searched. ；
2. The quality of the power supply currently in use is poor and unstable, causing interference in the surveillance camera screen;
3. The power supply voltage of the power supply system of the monitoring system is too large or unstable, resulting in a short circuit, open circuit, instantaneous overvoltage, etc. of the transmission line, and the monitoring camera may be damaged;
In particular, equipment damage due to power supply errors or instantaneous overvoltage is more likely to cause damage to the surveillance camera.
Therefore, when purchasing materials such as surveillance cameras and power supplies, you must be optimistic about what specifications you need, otherwise, the damage to the surveillance cameras will outweigh the gains.
