First, we should check the input voltage and current type of the surveillance camera, and select the appropriate power supply according to the rated power of the surveillance camera.

Usually, it is most appropriate to select a security monitoring power supply with a higher safety current. When the amperage is too low it will affect the life of the camera. However, it is more expensive for a higher current of CCTV power supply suppliers.

In addition, we need to know where it is used. For outdoor it needs not only waterproof function but also lightning protection function and heat dissipation performance of the CCTV camera power supply. The cooling performance of the power supply is particularly important.

In general, cameras are basically working 24 hours a day, which means that the power supply is also running 24 hours a day. The better the heat dissipation performance of power supplies, the longer the lifespan of the camera.

At last, consider the cost, and choose a reliable CCTV camera power supply manufacturer. Selecting the appropriate CCTV power supply can provide a solid guarantee for the entire security monitoring system.
