Abstract
A video surveillance system includes a first combiner, and a monitor, a power source and a camera control unit, each of which is electrically coupled to the first combiner. A regulated combiner located remotely from the first combiner and being electrically connected to the first combiner with at least one twisted pair of wires includes a voltage regulator which provides a regulated voltage to the camera located remotely from the first combiner. The camera is operable at a predetermined voltage level. The power supply provides an increased voltage to the regulated combiner through the first combiner and the twisted pair of wires to compensate for IR losses in the twisted pair of wires. Thus, the regulated combiner reduces the increased voltage to a safe level for the CCTV camera and other devices on a network to operate properly. The system dramatically increases the distance that a power supply can be located from where the camera is located, which decreases installation costs for CCTV surveillance systems.
