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?
Poor image quality when
testing using cable on a
reel?
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. Power is off.
b. Cable is incorrectly connected/crimped.
c. Cable was accidentally cut.
d. Wires running from pins 7 and 8
reversed.
e. Defective camera or remote video
device.
f. Defective video balun.
Induction from the coiled cable.
Possible Solution
a. Move the cable away from possible sources of
interference.
b. Install video amplifier between image processor andbalun.
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. Cat 5e cable meets
specifications in the manual. Cat 5e or better cable
allows longer range.
a. Check the power supplies of all devices connected to
the cable.
b. Check video signal of receiver.
c. Double-check that the cable was connected and
crimped properly.
d. Run a continuity test on all wires in the cable.
e. Reverse the wires.
f. Replace the unit with a new unit.
Test only with cable laid out in such a way that it is not
coiled and does not double back on itself.

WHAT IT IS
The EVT-TB1-42T and EVT-RB1-4T2 active video baluns are the quick, low-cost way to connect CCTV cameras
to a monitor, multiplexer, or video recorder at up to 1.5 miles (2,400 meters) away for monochrome cameras,
or up to 1 mile (1,500 meters) away for color cameras.
The baluns allow a CCTV camera’s video signal to be transmitted over low-cost Cat 5e unshielded twisted pair
(UTP) cable instead of costly coax cable. They are suitable for full-motion color and monochrome cameras.
