VideoEase CCTV Baluns

Quick Installation Guide
Introduction
The VideoEase CCTV Baluns eliminate 75-ohm coaxial cable and allow composite
baseband video to be transmitted via a single unshielded twisted pair (UTP) in a
structured cabling system. The VideoEase CCTV Balun is used in pairs to transmit
standard composite NTSC, PAL or SECAM video.
The CCTV Baluns are used with CCTV security and surveillance equipment such as
CCTV cameras, monitors, DVRs, IP camera encoders, video switchers and CCTV
camera servers. The CCTV Baluns may also be used with other composite
baseband video equipment such as DVD players, cable boxes, media servers and
audio-video monitors.
Installation
To install a VideoEase CCTV Balun, perform the following steps:
1. Identify the pin configuration of the baluns depending on the model used. One
twisted pair is required for each camera signal. Note: The CCTV Balun is
reverse polarity sensitive. Please ensure that “Ring” is connected to “Ring”
and “Tip” is connected to “Tip”. See diagram below.
2. The CCTV Balun works in pairs. Plug one CCTV Balun into the coaxial
connector of the CCTV camera.
3. Plug a second CCTV Balun into the coax connector of the CCTV monitoring
equipment (i.e.; DVR, mux, IP camera server, monitor) at the other end.
4. If the Modular CCTV Balun is used, connect an RJ45 line cord to each balun.
5. If the CCTV Screw Terminal Balun is used, use UTP cable with the outer
jacket spliced to expose the twisted pair. See diagram below.
6. Complete the connection between the two baluns, using standard UTP cable,
connector blocks and modular wall outlets. The CCTV Balun is reverse
polarity sensitive. Please ensure that straight-through wiring is maintained.
See diagram below.

7. Power-on the CCTV equipment and check the picture quality. The video should be
clear and sharp within the maximum specified distances. The following diagram shows
a typical application.
Troubleshooting
The following table describes some of the symptoms, probable causes and possible
solutions in respect to the installation of the CCTV Balun. If you still cannot
diagnose the problem, please call MuxLab Technical Support at (514) 905-0588 or
