Active Transmitter audio/video balun , 1 port to 2 outputs

1 port to 2 outputs

Our active transmitter provides for the transmission of one audio and video signal. This capability is useful for connection with both a monitor and a VCR (videocassette recorder) at the same time.
This amplified (active) product enables video transmissions up to 1.8km via Cat.2 or 3 UTP cabling..

The Model 121112 Video-Audio Transmitter also makes it possible for long-distance video signals to share the same wire bundling with data, telephony and low-voltage power circuits, thanks to the product special shielding design and low emissions capability. The Model 121112 also offers protection against voltage spikes and helps prevent interference from ground potential differences.

The transmitter offers multiple connection options, each unit equipped with both an RJ45 jack and a terminal block. The terminal block can be used with 16 to 24 AWG wire. The RJ45 jack is selected for 24 AWG UTP cable.
The transmitter is fully compatible with the Lemar P/N 121132 receiver, making them the perfect team for your video monitoring needs.
