Trouble Shooting:
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 wavy and shakes?
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.
Twisted pair wires reversed.
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.
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.
Try reversing polarity of the 2 wires at one end of cable.
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.

Typical Installation #1:
VG-1C12AQ
For short-run coax cable.
Figure 1:
Typical Installation #2:
VG-1C12AQ + EVT-PB1Q
For longer runs using CAT5 UTP cable.
Figure 2:
Ideal for new CCTV installations
where no passive video baluns
have been installed yet.
Also Available:
Video Balun with Ground Loop Isolator
EVT-PB1-V1TGQ
Installation:
Installation for ground loop isolators is very simple. The units are mounted in-line with the video signal.
To install, refer to figures 1 and 2:
1. Detach the video cable BNC connector from the camera BNC connector.
2. Attach the input side of the VG-1C12AQ to the camera BNC connector.
3. Attach the video cable BNC connector to the output side of the VG-1C12AQ.
