TROUBLE SHOOTING
WHAT IT IS
The EVT-PB1-V1TSQ Passive Video Balun is the quick, low-cost way to connect CCTV cameras to a monitor, multiplexer, or video
recorder at up to 2,000 feet away for monochrome or 1,300 feet away for color.
The EVT-PB1-V1TSQ allows a CCTV camera’s video signal to be transmitted over low-cost CAT5 unshielded twisted pair (UTP) cable
instead of costly coax cable. It is suitable for full-motion color and monochrome cameras.
INSTALLATION
NOTE: Video baluns are connected in pairs. One connects to the CCTV camera’s BNC connector, and the other 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 2,000 feet for monochrome or 1,300 feet for color. See fig. 1.
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. See fig. 2 and fig. 3.
a. Strip approximately ¼” (6mm) 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. See fig. 2.
b. Slide off the cover of the video balun.
c. At one end of the UTP cable, push the two stripped wires directly into the holes in the green connector (see fig. 3).
Tighten the screws to hold the wire in place. The wires should be fixed inside the two wire holes.
d. Repeat for the second video balun at the other end of the UTP cable. NOTE: The placement of the colored wires must
match in both video baluns. For instance, if the green wire is in the right hole and the white wire is in the left hole of the
first video balun, the green wire must be in the right hole and the white wire in the left hole of the second video balun.
4. Plug the video baluns into the BNC connector of the CCTV camera and 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.
6. Replace the covers of the video baluns. Make sure the wires come through the two small holes on the back of the units.
NOTE: Bare wires must not be exposed outside of the video baluns.

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.
c. Cable was accidentally cut.
d. Defective camera or remote video device.
e. 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 and 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. Check the power supplies of all devices connected to the cable.
b. Double-check that the cable was connected properly.
c. Run a continuity test on all wires in the cable.
d. Replace the camera or device with a new unit.
e. Replace the balun 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.

Multiple cameras
Standard CAT5 UTP cable includes four pairs of colored wires. Up to four CCTV cameras can be connected using EVT-PB1-V1TSQ
video baluns per single run of CAT5 UTP cable without interfering with each other under normal conditions. See fig. 4.
However, for installations where multiple cameras cannot be run over the same cable, separate cables must be run between the
cameras and the remote devices. See fig. 5.
Other cable types
The EVT-PB1-V1TSQ video baluns, when used with CAT5 UTP cable, offer the performance characteristics mentioned in this manual.
Other types of twisted 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.
