CCTV Power Supplies and 12V Adapters

A CCTV power supply has to match the voltage your cameras expect, which is usually 12V DC, and carry enough current for every camera on it. Here you will find single 12V adapters for one camera and multi-channel power supply boxes that feed several cameras from one fused unit. Add up the current each camera draws, leave some spare capacity, and pick a unit with enough outputs. A sealed battery is also listed for backup.
