The NVT Model NV-652R Video Receiver is an active (amplified) device that allows the transmission of real-time monochrome or color video on up to 1 mile (1, 6km) using Category 2 or better Unshielded Twisted-Pair (UTP) telephone wire.The unparalleled interference rejection and low emissions of the Model NV-652R 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.
