Description:
Video balun combiner for twisted pair up to 750 feet (228 meters).
The video balun combiner & security wallplate is a
unique transmission device that provides an economical
means of sending video, camera power and RS422
over a standard Category 5 cable. A typical system requires
a WB42S video balun combiner & wallplate at one end
of a 4-pair Category 5 cable, with a VB43FPD video balun
combiner at the opposite end. Video is sent over one
pair, RS422 over a second pair and camera power can
be sent over the two remaining pairs. A female BNC
connector provides video input. Punchdown terminals
are used to feed RS422 control and power in and out,
for connection to Category 5 cables. The video balun in the
WB42S provides the same high immunity to noise and
interference as all of the Nitek baluns.
The unique design of the WB42S allows the combination
of video, power and data in a 4-pair Category 5 cable.
This simplified wiring provides a convenient method of
powering the camera, allowing for quicker and easier
installations. The WB42S mounts to a standard electrical
box.

Wire and Cable Recommendations
The WB42S is recommended for use with unshielded twisted
pair (UTP) wiring. The systems will operate over wire gauges
from 24 AWG through 22 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 (25 pair or more) with an overall shield are 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.

and proper installation techniques, please call (800) 528-4343
