Rack Mount Dual Passive Video/Audio Transceiver

The NVT Rack Mount Dual Passive Video/Audio Transceiver NV-418AR Dual Video/Audio Transceiver is a rack-mount 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, Video Conferencing, or Distance Learning.

The unparalleled interference rejection and low emissions of the Model NV-418AR 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-418AR card slides into the NV-RM15 chassis. For stand alone applications, use the NV-418A.

NV-418AR features include:

→ No power required
→ Built-in transient protection
→ Exceptional interference rejection
→ Supports “up-the-coax” type control signals
→ Frequency Response DC to 10 MHz
→ RJ45, BNC and 1/4” TRS
→ Limited lifetime warranty
