Network Video Technologies NV-653T Video Transmitter 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. Baseband composite signals of any type are supported. The unparalleled interference rejection and low emissions of the Model NV-653T allows 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.
