Model NV-418AR

Dual Passive Video/Audio Transceiver

Features:

• Dual Full-motion monochrome or color video and audio at distances up to:

- 750ft (225m) when used with another NV-418A or NV-418AR

- 3,000ft (1km) when used with an active receiver such as the NV-518A or NV-518AR

• No power required

• Built-in transient protection

• Exceptional interference rejection

• Supports “up-the-coax” type control signals

• RJ45, BNC and 1/4” TRS

• Limited lifetime warranty

The NVT Model 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.
