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
Supply 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-Rectifiers
Input: AC or DC Output: 12 VDC Regulated. Ideal for long power cable
runs where voltage drop due to cable resistance is a problem.
   
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)
