The NVT model NV-653T video transmitter is an active (amplified) device that allows the transmission of real-time monochrome or color video up to 1.5 miles using category 5 unshielded twisted pair when used with an NV-652R. The unparalleled interference rejection ability of the Model NV-622R allows long run video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows you to use the shared or existing cable plant. Built-in ground-lifting ensures no annoying "hum-bars" when ground potential differences exist. With built-in transient suppression, damaging voltage spikes are eliminated. Mfr. #NV653T.
