NV-418A Dual Video/Audio Transceiver
The NVT Model NV-418A Dual 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, Video Conferencing, or Distance Learning.
The unparalleled interference rejection and low emissions of the Model NV-418A 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-418A comes with an RJ-45 patch-cord. For Rack-mounting, use the NV-418AR.
