View of the packaging
8-channel transmitter or receiver allowing to transmit video signals from 8 cameras via two 8-wire UTP cables. When used as the transmitter in pair with an active receiver, it can send the video signals over distances up to 1500 m, preserving their original quality. The device matches the 75 ohm impedance of the unbalanced source or load to the impedance of the balanced lines formed by the pairs of the UTP cable.
Used in video surveillance systems, the devices allow efficient design of transmission lines without hard wiring.
Distinguishing features
  • interference-free transmission of eight video signals
  • simpler and cheaper wiring - the eight video channels are transmitted via two UTP CAT5e cables
  • range of transmission with a passive receiver up to 330 m (in cooperation with two 4-channel baluns M16662 or with second 8-channel balun M16664)
  • range of transmission with active receiver (e.g. M16675) up to 1500 m
  • passive components - no power supply needed
  • built-in anti-interference filters
The type of cable and connector wiring
A UTP cable rated CAT5 or higher is required. The quality of the cable used has a direct impact on the image quality and transmission range.
The wires should be connected (using a crimping tool, e.g. J9210) in accordance with the scheme TIA/EIA-586B for RJ-45 connectors. Coaxial cables terminated with BNC plugs are to be connected to the BNC sockets.
