Model NV-623T Video Transmitter
Features: 3,000 to 4,000ft (900 to 1,2km) of Unshielded Twisted Pair wire Use with the NV-1662R for distances 1,000 to 4,000ft (300m-1,2km) Full motion monochrome or color video Patented 60dB crosstalk immunity Full ground-lifting Built-in transient protection Baseband NTSC, PAL, & SECAM compatible Limited lifetime warranty The NVT Model NV-623T Video Transmitter is an active (amplified) device that allows transmission of real-time monochrome or colour video on up to 4,000ft (1,2km) of standard telephone wire when used wuith the corresponding video receiver. Applications include Security/Surveillance, Video Distribution, or Distance Learning in intra- or inter-building environments. Supports NTSC, PAL, or SECAM. The unparalleled interference rejection ability of the Model NV-623T allows long run video signals to co-exist in the same wire bundle as telephone, datacom, or lowvoltage power circuits, allowing the use of a shared or existing cable plant. Groundlifting ensures no annoying "hum-bars" when ground potential differences exist. With built-in transient supression, damaging voltage spikes are eliminated.
