ENFORCER Video Ground Loop Isolator
2 SECO-LARM U.S.A., Inc.
The ENFORCER Video Ground Loop Isolator is a passive device that helps to
reduce ground loop interference caused by a difference in ground potential.
Ground loop isolators can be deployed in new installations or added to
existing installations.
ENFORCER Video Ground Loop Isolators should be installed on the camera
side of the cable and can be used with standard BNC coax cable or with video
baluns.

Troubleshooting:
Short
run using coax cable
Longer run
using CAT5e/6 cable
and video baluns
Wavy or ghost image if connected to
image processor (e.g., multiplexer or
DVR), but not if directly to monitor.
•Move the cable away from possible sources of interference.
•Ensure that the same twisted pair connects to a balun at both
ends of the cable.
•Replace the cable with a new cable.
Image background flutters between dark
and light.
•Remove a local power source, or adjust the monitor’s brightness
and contrast.
Image is wavy and shakes. •Try reversing the polarity of the 2 wires at one end of the cable.
Image is weak or faded.
•Reduce the cable length.
•Replace with a higher-grade cable. CAT5 cable meets the
specifications in the manual. CAT6 cable allows longer range.
No image. •Double-check that the cables were connected properly.
•Run a continuity test on all wires in the cable.
