4 Port Active UTP Video Balun Hub
Up to 1,500 feet (450 meters) with passive transceivers
Four port active video mini-hub with gain and loss control, built-in surge suppression, ground loop isolation 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.
These active video mini-hubs are multi-channel video receiver devices that provide a low cost means of receiving quality live video over category UTP cabling. The systems can also adapt to existing communication and computer network spare pairs or new cable installations. The VH451 can be used on video runs up to 1,500 feet (450 meters) when used with passive transmitters. These hubs provide superior immunity from noise and interference, even when run in common raceways with AC.
- Quality video over ordinary twisted pair cable
- Built-in surge suppression
- Built-in ground loop isolation
- Convenient access to DIP switches for accurate gain and loss control
- High immunity to noise and interference
- LEDs to indicate video detection
- Compact design
- Video can be run in the same cable with telephone, computer signals and power
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. 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.
