Baseband (composite) signals of any type are supported."Up-the-coax" type signal may be sent over the same wire pair at distances up to 750ft (225m).The unparalleled interference rejection ability of the Model NV-1613 Hub allows video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. Perfect for larger CCTV installations where port density and camera number growth are prevalent. With built-in transient protection, damaging voltage spike problems are eliminated.
