Overview:

BNC Connector

Dimensions:

1. Video baluns are connected in pairs. Connect one balun to the CCTV camera’s BNC connector. Connect another balun to

the BNC connector of a DVR or other remote device. NOTE: Only one of the baluns will be the EB-P101-24GQ. Please use
another ENFORCER passive video balun, such as the EB-P101-01Q for the other side.

2. Make sure the distance between the camera and the remote video device does not exceed 1,950ft (600m) for black and

white video or 1,300ft (400m) for color video.

3. Run a Cat5e/6 cable (UTP) from the remote video device to the camera.

4. Connect the Cat5e/6 cable to both baluns. NOTE: Video baluns are polarity-sensitive.
a. Strip approximately

1

/4” (6mm) of insulation from the same wires at both ends of Cat5e/6 cable.

b. Push down the small tabs above the terminals. Insert the wires into the corresponding terminals. See “Overview” above

for more information. After the wires have been inserted into the terminals, there should be no bare wire showing.

5. Connect the black terminal to an earth ground using a grounding wire (not included) if extra surge protection is desired.

6. Connect the video baluns into the BNC connectors of the CCTV camera and the remote video device.

7. Test the connection by powering up the CCTV camera and remote video device to make sure they operate as expected.

DVR), but not if directly to monitor.

 Move the Cat5e/6 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 Cat5e/6 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 polarity of the two wires at one end of the

Cat5e/6 cable.

Image is weak or faded.

 Reduce the Cat5e/6 cable length.
 Replace with a higher-grade cable. Cat5e cable meets the

specifications in the manual. Cat6 cable allows longer range.

No image.

 Double-check that the Cat5e/6 and BNC cables are

connected properly.

 Run a continuity test on all wires in the cable.
 Check that the camera and monitor are powered up.
