The K2-8CH (or HD8C96W) is an 8-channel, 96W centralized CCTV power supply box designed for \(12\text{V}\)–\(15\text{V}\) DC cameras. It features a wide AC input (\(110\text{-}230\text{V}\)), adjustable voltage (\(12\text{V}\), \(13.5\text{V}\), \(15\text{V}\)) to compensate for long cable runs, and individual port protection against overloads and short circuits, housed in a flame-retardant shell.
