NV-314A Video/Audio Transceiver
The NVT Model NV-314A Video/Audio Transceiver is a passive (non-amplified) device 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.
Applications include Security/Surveillance, Video Distribution, or Distance Learning.
The unparalleled interference rejection and low emissions of the Model NV-314A allow video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of a shared or existing cable plant. Up-the-coax type signal may be sent over the same wire pair.
The NV-314A comes with an RJ-45 patch-cord. For Rack-mounting, use the NV-418AR, which contains hardware equivalent to two NV-314As.
