DESCRIPTION :
Our Active video balun provides long-distance transmission of real-time color and monochrome video signals as well as all baseband (composite) signals. This amplified (active) product enables video transmissions up to 1.8km via Cat.2 or 3 UTP cabling.

The Active video balun 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. It also offers protection against voltage spikes and helps prevent interference from ground potential differences.
