NVT NV-208A-M Specsheet

Model NV-208A-M

Video Transceiver

Features:

• Full-motion CCTV video at distances up to 750ft (225m) when used
with any passive NVT transceiver or hub

• Up to 3,000 feet (1,000 m) with a DigitalEQTMHub or active receiver

• Up to 1,500 feet (460m) shall be supported by any NVT StubEQTMHub

• Male BNC allows connection directly to the camera or DVR

• Reliable Screwless UTP terminal connection

• No power required

• Exceptional interference rejection

• Built-in transient protection

• Supports “up-the-coax” type control signal up to 750ft (225m)

• Limited lifetime warranty

The NVT Model NV-208A-M Video Transceiver is a passive (non-amplified) device that allows the trans­mission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire.
Baseband (composite) signals of any type are supported.

An improvement over NVT’s popular NV-213A video transceiver, the passive NV-208A-M features a
Screwless UTP terminal block and Male BNC allowing connection directly to the camera or DVR. It is
capable of delivering a fully equalized signal to the DVR when used with any Active NVT Receiver, yet
is compatible with all of NVT’s passive products for applications under 750ft (225m). The NV-208A-M
Video Transceiver also incorporates improved transient protection that eliminates the need for a ground
screw.

The unparalleled interference rejection and low emissions of the NV-208A-M 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.
