Power supplies for video surveillance

Power supply

— a device that converts mains voltage into regulated power required by cameras, controllers, readers, and other security equipment. When choosing one, it is important to match the output voltage, while the current capacity should cover the total consumption of the connected equipment. The number of channels, connector type, enclosure design, and the possibility of installing a backup battery should also be taken into account. Insufficient power can lead to reboots, interference, and unstable system operation.
