The importance of a power supply for your video security cameras cannot be overstated. Installers and users should use a high-quality power supply to ensure the stability and reliability of their video surveillance system. Image distortion, flickering, and even security camera hardware damage can all be caused by a poor power supply.
Outdoor security cameras typically use a 12V DC power source, while PTZ cameras use a 24V AC power supply. Some security cameras may use 220V AC power, and inside security cameras commonly use a 5V DC power supply.
A power supply is required for all security cameras. In most security camera systems, power boxes and power converters are employed. Most installers will utilize a power adapter and splitter if installing four or fewer cameras, but a power distribution box if installing more than four cameras. If you’re looking for a power adapter, make sure it is from a reliable electrical enclosure manufacturer and can handle the voltage you’ll be using.
