DESCRIPTION :
The Model 121132 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 121132 also offers protection against voltage spikes and helps prevent interference from ground potential differences.
The receiver 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 designed to complement the Lemar 121112 transmitter. Let Lemar provide you with the perfect team for all your video monitoring needs.
