Overview

The VH1656 is a 16 port active video hub with dual outputs, built-in surge suppression, ground loop isolation, gain/loss control, and video detection. Systems operate with other Nitek UTP video equipment including, video transceiver hubs, standard video balun transceivers, active transmitters, or any twisted pair equipped camera.

Multi-channel video receiver hubs provide excellent video quality through two video outputs per channel. Twisted pair installations are made with a choice of the standard screw terminal connections, or the modular jack connections featured on the M series. The VH1656 can be used on video runs up to 3,000 feet (900 meters) when used with passive transmitters, or distances of up to 6,000 feet (1,800 meters) with the Nitek TT560 active transmitter. These hubs provide superior immunity from noise and interference, even when run in common raceways with AC power.

Wire and Cable Recommendations

We recommend using unshielded twisted pair wiring. The systems will operate over wire 26 to 18 AWG but are optimized for 24 AWG. Category cables may be used. Individually shielded pairs should be avoided, as they drastically reduce the operating range of the systems. Multipair cable with an overall shield is acceptable. Video can be operated in the same communication cable coexistent with telephone, computer, control signals, power voltages, and other video signals. While video may be routed through telephone punch-down block terminals, any bridge-taps, also called T-taps and any resistive, capacitive or inductive devices MUST BE removed from the pair.
