Know The Basics Of Power Supply For Analog CCTV

 Bad standard power supply can guide to image distortion, flickering, even harm of CCTV hardware. Characteristically, outside CCTV use 12V DC power supply, and PTZ cameras use 24V AC power supply, some safety cameras may utilize 220V AC power, 5V DC power supply is extensively utilized in inside CCTV in Mumbai.


All safety cameras need some kind of power source. Power distribution boxes and BIS power adapters in India are utilized in most fitting of safety cameras. If fitting 4 cameras or less, most installers will select to utilize a power connecter and splitter although installations including more cameras, they will utilize a power issuing box. When selecting a power connecter, make sure to get one that helps the power and amperage scores for your cameras.

12V DC or 24VAC: How to choose Power Supply?

Choosing the AC 24V battery backup power supply in Mumbai, because in the similar transmission distance, higher the power, lower the utilization. High power can permit CCTV to get adequate power supply.

The precise technique is accumulating the valued power, then multiply 1.3, the result is the actual essential CCTV power supply. Furthermore, you want to reflect the cable power utilization and power budget.

An example:

If we are fitting 100 units safety cameras in a viable building, the valued power utilization is 4W for the safety camera. How to analyse the essential power supply for CCTV?

Safety camera power utilization: 4W x 100 units x 1.3 = 520W

After the utilization, the desired power rating: 520W x 1.3 = 676W

Cable utilization and power budget: 676W x 1.3 = 878W
