Description:
Video Balun Transceivers for twisted pair up to 1,000 feet. Two types
are available. The basic VB37 model and the VB39 with built-in surge
arresting for added equipment protection.
Video Balun Transceiver is a video transmission device
that provides a low cost means of sending live video over unshielded
twisted pair, point-to-point wiring for distances of up to 1,000 feet
(750 feet when used with DVR equipment). The VB37 and VB39 are
compatible with all of the “up-the-coax” control systems.
A basic system uses (2) VB37 or (2) VB39 units, one at
each end of a twisted pair of wires. These units 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.
The VB37 and VB39 are designed to provide superior
immunity from noise and interference even when running next to line
power!
Features:
- Quality video over ordinary twisted pair cable
- Immunity to noise and interferenc
- Built-in surge protection on VB39 models\
- Passive devices - do not require power
- Video & P/T/Z over a single pair (with “up-the-coax”
systems)
- M - version mounts directly to camera or video source
- Weather resistant design
- Easier to install than coax
