Description:
The VB41x8 modular card is designed for use with the modular rack system. Each card has 8 video
balun units, built-in surge protection and video loss
detection.
The Nitek video baluns are transmission devices that
provide a low cost means of sending live video over
unshielded twisted pair, point-to-point wiring for distances
of up to 750 feet (228 meters). The Nitek video baluns are also compatible with all of the “up-the-coax” control systems.
A basic system would require one unit at each end of a twisted pair of wires. The Nitek video baluns
are intended for use over existing in house telephone
wiring, Category 5 wiring or other twisted pair cable
runs to provide a convenient, cost-effective alternative
to coax. Nitek video baluns are designed to provide
immunity from noise and interference, even when
running next to line power!
The VB41x8 plugs into the VH3200 card cage, which
holds up to modular cards. This modular “plug-in” feature
allows the system to be custom configured for each
application and provides easy expandability. |
Features:
- Quality video over ordinary twisted pair cable
- Built-in surge suppression
- Immunity to noise and interference
- Built-in video loss detection
- Video & P/T/Z over a single pair (with “up-the-coax”
systems)
- RJ45 or push terminals for easy connection

Wire and Cable Recommendations
The Nitek video balun is recommended for use with unshielded
twisted pair (UTP) wiring. The systems will operate
over wire gauges from 26AWG through 12AWG. Category 2,
3, 4 or 5 cable 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.
