If you own a digital video security system, chances are you also own Closed Circuit TeleVision or CCTV power distribution boxes. These are literally the powerhouse for the digital video cameras and illuminators used in complete systems.
There are three major components to a digital video security and surveillance system; the cameras, the Digital Video Recorder or DVR, and the monitor(s).As far as power requirements are concerned both the DVR and the monitor normally take care of themselves. In other words, they both have household 110 AC plug-in cords, so all you need to do to get them power is plug them into an outlet (we recommend a properly rated surge suppressor). The cameras on the other hand, are a different story altogether.
