Cat Code: TP-TX/RX

Single-Cable Twisted-Pair TX & RX System for Transmission of Video & Audio up to 1200 metres over CAT-5 LAN or Telephone Cable.

$199

Transmitter & Receiver (Power Supply not included)

Differential Amplifier Link for the Transmission of Colour Video & Audio up to 1.2 kilometres using Low-Cost Flexible Twisted Pair CAT-5 LAN or Telephone Cable.

This system allows unbalanced 75 ohm Composite Colour-Video and Line-Level 10 000 ohm Audio signals to be transmitted up to 1200 metres over Flexible, Low-Cost, Small-Diameter Category-5 100 ohm impedance Unshielded-Twisted-Pair (UTP) Local-Area-Network (LAN) cable (see 8C/CAT5) or common Telephone cable.

TP-TX/RX 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.

Excellent results with Cat-5 cable, we recommend testing to assess results with common 600 ohm impedance Telephone cable.

• Use an easily installed low-cost single CAT-5 (4 pair) Cable for Video, Audio, Sensor and Power Supply, or utilise existing LAN or Telephone Cabling.

• 6 equalisation settings for Transmission of Monochrome or Colour Composite Video Signals up to 1.2 kilometres.

• For Video Transmission less than 500 metres see: BALUN-100/75

• Balanced Transmission virtually eliminates induced noise.

• System may be integrated with PIR sensor, alarms, etc.

• Reduces installation cost & difficulties associated with high-loss, inflexible, traditional coaxial cable.

  • Recommended cable: CAT-5 UTP, LAN, 4 pair (24 AWG, 22 AWG, 20 AWG)

  

  Normally Category-5 LAN 4-pair Cable is used to interconnect the Transmitter & Receiver, the pairs carry Video, Audio, Sensor Contacts and 24 ~ 30 VDC Supply (up to 200 metres) to TX.

  Transmitter:
  Output: 12 VDC regulated for Video Camera, Audio Amplifier & Sensor.
  Inputs: Video, Audio, Sensor Contacts, 24 ~ 30 VDC via Cat-5 Pair from RX (up to 200 metres otherwise 18 ~ 28 VDC from a separate power supply, see note below **) .

  Receiver:
  Outputs: Two Composite Video & One Audio.
  Input: 24 ~ 30 VDC.

  Twisted Pairs:
  Between TX & RX carry Video, Audio, Sensor contact conductors & DC Power.

  When there are limited Pairs available to interconnect TX and RX, the transmitter may be powered directly and the Twisted Pair(s) used to carry Video and/or Audio.

  ** Any spare pair(s) may be paralleled with RX-to-TX DC Power conductors to extend DC via twisted pair length from 200 metres to 400 metres (2 pairs) or 600 metres (3 pairs).
