NV-452R NVT 4 Channel Active UTP Video Receiver 24VAC/DC

The NVT Model NV-452R 4-Channel Video Receiver is an active (amplified) device that allows the transmission of real-time monochrome or color video on up to one mile (1,6km) using Category-2 or 3 Unshielded Twisted-Pair (UTP) telephone wire, or up to 1.5 miles (2,4km) (NTSC) using Category-5 or better.
The unparalleled interference rejection and low emissions of the Model NV-452R allow long run video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of shared or existing cable plant. Ground-lifting ensures no annoying "hum-bars" when ground potential differences exist. With built-in transient protection, damaging voltage spike problems are eliminated. The built-in sharpness and brightness controls compensate for cable loss.
