What it is:
The EVT-PB1-V1TGQ is a Passive Video Balun with Ground Loop Isolator.
A Passive Video Balun allows a CCTV camera's video signal to be transmitted over low-
cost CAT5 unshielded twisted pair (UTP) cable instead of costly coax cable. They are
suitable for full-motion color and monochrome cameras and provide a quick, low-cost way
to connect CCTV cameras to a monitor, multiplexer, or video recorder at up to 980 feet
away.
Video ground loop isolators are passive devices that help to reduce ground loop
interference caused by multiple building grounds and differences in ground potential.
Ground loop isolators can be installed in new installations or added to existing
installations. Video ground loop isolators should be installed on the camera side of your
cable.

Installation:
NOTE: Video baluns are connected in pairs. The EVT-PB1-VITGQ connects to the CCTV camera’s
BNC connector, and a standard passive video balun (EVT-PB1Q purchased separately) connects to
the BNC connector of a remote video device. See fig. 1.
1. Make sure the maximum distance between the CCTV camera and the remote video monitor,
recorder, multiplexer, or other device to which it is connected does not exceed 980 feet. See fig. 2.
2. Run the UTP cable from the remote video device to where it will be connected to the CCTV
camera. Follow the CCTV camera’s wiring instructions for information on how to safely run and
hide this wire.
3. Connect the UTP cable to the two video baluns. NOTE: The video baluns are polarity-sensitive.
a. Strip approximately ¼” of insulation from two of the wires at one end of the UTP cable. Do the
same to the two same-colored wires at the other end of the cable. (Note: Use the convenient
"Ideal Copper Length" gauge on the bottom of the balun.)
b. Attach the wires to the baluns. Note the polarity of the wires. See fig. 1
4. Plug the video balun with ground loop isolator into the BNC connector of the CCTV camera and
the other video balun into the remote video device.
5. Test the connection by powering up the CCTV camera and remote video device to make sure they
operate as expected.
NOTE: Bare wires must not be exposed outside of the video baluns.
Multiple cameras:
Standard CAT5 UTP cable includes four pairs of colored wires. Up to four CCTV cameras can be
connected using video baluns per single run of CAT5 UTP cable without interfering with each other
under normal conditions.
Other cable types:
The ENFORCER video baluns, when used with CAT5 UTP cable, offer the performance characteristics
mentioned in this manual. Other types of twisted-pair cable can be used as well. However, the
performance characteristics vary from cable to cable, and so care must be taken when using other
types of cable. Specifically, the maximum distance between the camera and the remote device may
decrease significantly with lower grades of cable.

Trouble Shooting:
Max. 980’ (300M)
Problem
Wavy or ghost image if
connected to image processor
(e.g., multiplexer or DVR), but
not if directly to monitor?
Image background flutters
between dark and light.
Image is weak or faded?
No image?
Possible Cause
a. Strong electromagnetic interference.
b. Poor signal, or balun separation is too long.
c. Split pairs.
d. Crimped cable.
Interference from external power source.
a. Exceeded recommended balun separation.
b. Using lower-grade cable than recommended.
a. Cable is incorrectly connected.
b. Cable was accidentally cut.
c. Defective camera or remote video device.
d. Defective video balun.
e. Twisted pair wires reversed.
Possible Solution
a. Move the cable away from possible sources of interference.
b. Replace with active balun.
c. Ensure same twisted pair connects to balun at both ends of cable.
d. Replace cable with new cable.
Remove power source, or adjust monitor's brightness and contrast.
a. Reduce cable length.
b. Replace with a higher-grade cable. CAT5 cable meets specifications
in the manual. CAT6 cable allows longer range.
a. Double-check that the cable was connected properly.
b. Run a continuity test on all wires in the cable.
c. Replace the unit with a new unit.
d. Replace the unit with a new unit.
e. Try reversing polarity of the 2 wires at one end of cable.
