8-Channel Video Passive Transceiver Hub

The NVT 8-Channel Video Passive Transceiver Hub NV-813 is an 8 port passive transceiver hub that allow transmission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. Baseband (composite) signals of any type are supported. “Up-the-coax” type signal may be sent over the same wire pair at distances up to 750ft (225m).

The unparalleled interference rejection ability of the Model NV-813 Hub allows video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. Perfect for larger CCTV installations where port density and camera number growth are prevalent. With built-in transient protection, damaging voltage spike problems are eliminated.

NV-813 features include:

→ High-Density 19" 1U high enclosure features 8 ports
→ Use with any NVT passive transceiver or hub as a rack-mountable passive transceiver for full motion CCTV at distances up to 750ft (225m)
→ Use with any NVT DigitalEQ™ or active receiver hub as a rack-mountable passive transmitter for distances up to 3,000ft (1km)
→ Use with any NVT StubEQ™ for distances up to 1,500ft (460m)
→ RJ45 video connectivity with optional NV-RJ45A RJ45 to-screw-terminal adaptors included
→ No power required
→ Exceptional interference rejection
→ Frequency Response DC to 10 MHz
→ Built-in transient protection
→ Supports “up-the coax” type control signal up to 750ft (225m)
→ Compatible with qualified UTP cameras
→ Includes eight 2ft (60cm) coax jumper cables and rackmount hardware
→ Limited lifetime warranty
