NV-518A Dual Video/Audio Transceiver
The NVT Model NV-518A Dual Video/Audio Transceiver contains one amplified receiver that allows transmission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. An additional passive port is included allowing the support of bi-directional video, or as a second receive path up to 1,000ft (300m). Alternately, the ports may be combined to allow the NV-518A to function as a repeater. 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-518A 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. Video signals traveling in opposite directions in the same wire bundle are limited to 1,000ft over Category 2 or 3, and 2,000ft over Category 5 wire.
The NV-518A comes with an RJ-45 patch-cord and power supply. For Rack-mounting, use the NV-518AR.
