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

REG-12VDC * Rect-Reg * Rect-Reg+

In-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.
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)
