VideoEase CCTV Baluns

(500000, 500000R, 500009, 500023, 500031)

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 toll-free in North America at 877-689-5228.

Symptom

Poor picture quality, distortion, interference, etc.

Probable Causes

1. EMI interference.

No video image

Picture faded or weak

Horizontal bars or lines moving up or down the screen

Possible Solutions

Check that wiring is not too close to transformers and ballasts.

2. Wires reversed on signal pair on one side

3. Split pair

1. Power-off.

2. Wrong pin configuration

3. Defective CCTV

Balun

1. Exceeded distance specifications

2. Lower grade UTP cable is introducing high signal losses.

Make sure that the wires on the signal pair are not reversed on one side.

Check if the UTP pairs are split and correct. Each signal pair must be twisted.

Check power supplies of CCTV equipment.

Check pin configuration and verify straight-through wiring.

Change CCTV baluns for another pair.

Check DC loop resistance and verify if distance spec is exceeded. Reduce cable length or eliminate high-loss components.

Use signal repeater for extended distance.

1. Possible ground loop.

Replace cable by higher grade.

Lift AC ground or install ground loop blocker. Alternatively, install

MuxLab’s CCTV Ground Loop

Isolation/Pass-Thru Balun (500132) at the DVR or camera.
