The active UTP video transmitter is used to transmit four video signals via 8-wire CAT5e UTP cable over distances up to 2400 m (using an active receiver) or over distances up to 1500 m (using a passive receiver), preserving original video quality.
The device matches the 75 ohm impedance of the unbalanced sources to the impedance of the balanced lines formed by the pairs of the UTP cable. Used in video surveillance systems, such devices allow efficient design of transmission lines without hard wiring.

Distinguishing features
- interference-free transmission of four video signals
- the four channels use one 8-wire CAT5e UTP cable - it's cheaper and better solution than troublesome long coaxial lines
- maximum transmission distance 2400 m (using complementary active receiver)
- 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.
RJ-45 wiring
Settings
Depending on the length of the transmission line, the slider of the "Level" switch should be set to the lowest level (left position) for a distance of 1400-1700 m, to the medium level (middle position) for a distance of 1700-2000 meters, or to the highest level (right position) for a distance of over 2000 meters. The distance ranges are given for CAT5e UTP cable. Using other wiring, the level settings may be appropriate for slightly different distance ranges.
