Model NV-314A
Passive Video/Audio Transceiver
Features:
• 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
• RJ45 and RCA jack connections
• Limited lifetime warranty
The NVT Model 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.

*Video signals traveling in opposite directions may co-exist in the same wire bundle up to 1,000 ft (300m), 2,000ft (600m) if Cat5 or better is used.
**For Digital Recording applications, it is recommended that Passive to Passive transmission (Example: NV-314A to NV-314A) distances be limited to no more than
750 ft. For distances greater than 750 ft. please use an NVT Active Receiver product like the NV-518A.
