ENFORCER 4-in-1 HD Ground Loop Isolator
Introduction:
The ENFORCER 4-in-1 HD 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 4-in-1 HD Ground Loop Isolators should be installed on the DVR side of the cable
and can be used with standard BNC coax cables or with 4-in-1 HD video baluns.

Troubleshooting:
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 wavy and shakes
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
Remove a local power source, or adjust the monitor's brightness
and contrast
Try reversing the polarity of the two wires at one end of the cable
Reduce the cable length
Image is weak or faded
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
