The NVT Model NV-813S is a compact 8-channel passive transceiver hub that allows transmission of
real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. 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-813S 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.
