5A power supply
Do you need a power supply for cameras? This 12Vc and 5A power supply is used as a generic source for surveillance cameras. Most surveillance cameras have a consumption less than 1A. Just consider the voltage and current your camera needs. If your camera needs 12Vc, and less than 5000mA you can use this transformer.
Normally a camera consumes less than 500mA, with this 5A feeder you could connect several cameras with a single feeder.
