Use Flexible - Low-Cost - Small-Diameter Category-5 or Category-6 100 ohm impedance Unshielded Twisted-Pair (UTP) Local-Area-Network (LAN) cable or common TP 120 ohm Telephone cable to transmit unbalanced 75 ohm Composite Video signals:

Up to 600 metres (monochrome) and up to 300 metres (colour) using Passive Baluns with high quality unshielded Cat-5/6 LAN cable.

Up to 2 400 metres (monochrome) and up to 1 500 metres (colour) using Active Amplifiers with high quality unshielded Cat-5/6 LAN cable.

Baluns or Active Amplifiers may save hundreds of dollars on coax cable and labour and ensure that you get-the-job! Use in Residential Units, Universities, Offices, Hospitals, Showrooms, Elevators, for Covert Surveillance. Utilise unused spare pairs that may be available in existing LAN or Telephone wiring.

Different devices may be used at each end of Twisted Pair.

An Active Amplified Transmitter or Receiver may be used with a passive device to extend the transmission distance.

Single-Cable-Solution 600 + metres use spare pair(s) for Power SupplyIn-Line Regulator-Rectifier Input: 14~24 vac or 18~30 DC via Screw-Terminal Block. Output 12 VDC Regulated (maximum 300 mA when input is less than 20 volts, 200 mA when input is greater than 20 volts) via 2.1 mm x 5.5 mm Center = + DC Plug. Ideal for long power cable runs where voltage drop due to cable resistance is a problem. for In-Line Rectifier/Regulator.

Technical Information: Ask for our 'Balun Link List' a very useful resource for general Balun information, e-mail your request with your Balun purchase Invoice Number.

PC DVRs & other Digital Video Recording systems: We recommend use of high quality Cat-5/6 cable, if runs exceed 250 ~ 300 metres use TWIST-AMP for better results.

To ensure best possible image contrast and brightness in Low-Light conditions we recommended High-Quality Low-Loss Coaxial Cable and AV-Amp or Vid-Amp/4 for long runs, acceptable results may be possible with unshielded Cat-5/6 Cable and TWIST-AMP.

Twisted Pairs may be paralleled to extend the transmission distance of Video Signals however any gain will be a trade-off as paralleled pairs lower immunity to common-mode interference and increase attenuation of high frequency signals.

In-Line Regulator
Cable resistance, Cable length and Current drawn by Camera affect voltage drop which can be reduced by using thicker gauge wire and/or paralleling pairs. A test using 24 AWG Cat-5  Cable, a 24 vac Power Supply, REG-12VDC In-Line Rectifier-Regulator and a Camera that draws 100 milliamps demonstrated that lengths of 600 + metres is practical, 2 pairs in parallel would increase this to 1 200 + metres.

A single 24 AWG (0.5 mm diameter) conductor has a resistance of ~ 9.4 ohms per 100 metres, voltage drop will be ~ 1 volt per 50 metres of Cat-5 Twisted Pair when powering a Camera that draws 100 milliamps. (calculation: 9.4 ohms x 0.1 amps = 0.94 Volts)
