As long as the switching power supply is a DC constant voltage design, it will not damage the surveillance cameras. My personal experience shows that a centralized power supply solution is not only convenient to manage but also easy to maintain. Considering that a 12V surveillance camera typically only requires 0.6A of current, this 12V 33A 400W power supply can easily meet the power needs of more than 20 cameras.
This power supply has sufficient power and remains stable even when powering multiple cameras simultaneously. In fact, this configuration is not only suitable for ordinary surveillance cameras but also for some devices that require higher power, such as infrared night vision cameras or high-resolution cameras. In practical applications, I have successfully provided a stable power supply for more than 20 cameras, ensuring the normal operation of the system.
The advantages of centralized power supply are that it simplifies wiring, reduces the use of power cords, and lowers maintenance costs. Furthermore, centralized power supply allows for optimized power management, such as monitoring power status through software to ensure that each camera receives adequate power.
Therefore, if your surveillance system has more than 20 cameras, this 12V 33A 400W switching power supply is an ideal choice. It not only meets current needs but also provides ample room for future expansion.
