A CCTV power supply unit, also known as a power distribution box, allows surveillance system installers to easily manage the power to multiple CCTV cameras at a central point (usually at the location of the DVR). This allows your camera installation to be neater. For example, instead of having 8 power supply plugs plugged into a power strip/electric surge protector, all of your camera power wires can neatly be run to a power supply box. A power supply box is normally installed near your DVR. Our power supply boxes are very simple to install. Each camera’s power cable simply screws into the power supply box. The power supply box plugs into a standard power outlet. No electrician is required for the installation of the box.
