How to Choose Power Supply For CCTV Camera?

It’s undeniable that power supply is crucial important to your video security cameras. For ensuring the stability and reliability of your video surveillance system, installers and users should choose high quality power supply. Poor quality power supply can lead to image distortion, flickering, even damage of security camera hardware. Typically, outdoor security cameras utilize 12V DC power supply, and PTZ cameras use 24V AC power supply, some security cameras may use 220V AC power, 5V DC power supply is widely used in indoor security cameras.

POWER ADAPTERS OR POWER BOXES?

All security cameras require some sort of power source. Power boxes and power adapters are used in most installations of security cameras. If installing 4 cameras or less, most installers will choose to use a power adapter and splitter whereas installations involving more cameras, they will use a power distribution box. When choosing a power adapter, be sure to get one that supports the voltage and amperage ratings for your cameras.

SECURITY CAMERA SUPPORTS BOTH DC12V/AC24V, HOW TO CHOOSE POWER SUPPLY?

Selecting the AC24V power supply, because in the same transmission distance, the higher voltage, the lower of consumption. High voltage can allow camera to get sufficient power supply. Meanwhile, using AC 24V, when debugging security cameras, you can choose sync power supply, this can sync image vertical frequency across different devices.

HOW TO PROVIDE SUFFICIENT POWER TO SECURITY CAMERAS?

This question is difficult to answer for those inexperienced installers, many of them find the power capacity isn’t sufficient in real installation, they have to increase additional power supply. Actually, the security camera needs large current when it firstly boots, plus the transmission consumption, therefore, to calculate total required power supply, doesn’t mean you simply add rated power of each cameras together. The correct method is adding the rated power, then multiply 1.3, the result is the real required power supply for security cameras, additionally you need to consider the cable power consumption and power budget
