BalUns composite Video twisted pair Network Cable
Use these Baluns for transmission of Composite Video 300 ~ 600 metres using UTP Network or Telephone Cable
 
Future-Proof new installs use UTP (more easily & at less cost than Coaxial Cable) re-use it for Network (Megapixel) Cameras in the future

 
BalUns for transmission of common composite Video over a Network or Telephone twisted pair. 4 individual signals can be carried over a single, flexible, easily-installed, low cost 4 pair UTP Cat-5, Cat-5e, Cat-6 LAN Cable.
 

Single-Cable-Solution, use spare pairs in a 4 pair Network Cable to carry Power & Audio & Data (RS485).
 
These passive BalUns are suitable for transmission up to ~600 Metres using high quality UTP LAN Cable, we recommend testing to assess results with Telephone Cable. Active Amplifiers can be used at Transmitting &/or Receiving ends to compensate for high-frequency-attenuation (image detail, colour) & other losses.

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.

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.

how to connect camera balun rectifier
Cable resistance, Cable length and Camera current affect voltage drop, this can be reduced by using thicker wire &/or paralleling pairs. With 24 AWG Cat-5 Cable, 24 vac Power Supply, REG-12VDC Rectifier-Regulator and a 100 milliamp Camera lengths of 600 + metres are 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)
