Audio up to 2.4 kms using Unshielded Twisted Pair cables, CAT-5, CAT-6 LAN & TP Telephone Cable

Future-Proof new installations, install UTP (at less cost than Coaxial Cable) and re-use it for Network (Megapixel) Cameras in the future.

Amplifiers for transmission of composite Video &/or Audio using common UTP (LAN) Network Cables or TP Telephone Cable.

Use a single 4-Pair Cable for Video, Audio, Data (RS485) & Alarm or Power.

These Active Amplified devices will function up ~2400 Metres using high quality Network Cable - we recommend testing to assess results with common 120 ohm impedance TP Telephone cable as results are variable.

Passive Baluns are used in Pairs one at each end of Twisted Pair NO POWER REQUIRED

Different devices may be used at each end of Twisted Pair

An Amplified Transmitter or Receiver may be used with a passive device to extend transmission distance, compensate for losses, etc.

Results may vary depending on output level of Source device (Camera, etc), input sensitivity of Receiving device (DVR, Monitor, etc), interconnections and Cable characteristics.
