Description:
32 port powered video hub with built-in surge suppression 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.
The VH3200 series UTP modular hub system holds up to four VB41x8, TR515x8 or TR560x8 8 channel video receiver cards in any combination, for a total of 32 input ports. The VB41x8 can be used on video runs up to 750 feet (228 meters). The TR515x8 can be used up to 1,500 feet (457 meters) with passive transmitters. The TR560x8 can be used up to 3,000 feet (914 meters) with passive transmitters and up to 6,000 feet (1,828 meters) with the NITEK TT560 active transmitter.

Wire and Cable Recommendations
Twisted Sender is recommended for use with unshielded
twisted pair (UTP) wiring. The systems will operate over wire
gauges from 26 AWG through 12 AWG but are optimized for 24 AWG. Category cabling may be used. Individually shielded
pairs should be avoided as they drastically reduce the operating
range of the systems. Multi-pair 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.
For more specific information regarding wire types, gauges and proper installation techniques, please call (800) 528-4343 for technical assistance.
