Passive Video & Audio Transceiver

The NVT Passive Video/Audio Transceiver NV-314A Video/Audio Transceiver is a passive (non-amplified) device that allows transmission of real-time monochrome or color video and audio 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 RJ45 patch-cord. For rack-mounting, use the NV-418AR (which contains hardware equivalent to two NV-314As) with the NV-RM15 rack system.

NV-314A features include:

→ Full-motion monochrome or color video and audio at distances up to = 750ft (225m) when used with another passive transceiver; 3,000ft (1km) when used with an active receiver such as the NV-518A
→ No power required
→ Built-in transient protection
→ Exceptional interference rejection
→ Supports "up-the-coax" type control signals
→ Frequency Response DC to 10 MHz
→ RJ45 and RCA jack connections
→ Limited lifetime warranty
