Model NV-872 8-Channel DigitalEQ Active Receiver Distribution Amplifier Hub TM Front Rear RJ45A Adaptors Included Features: TM • Adaptive DigitalEQ fully automatic 4-band equalisation provides adjustment-free equalisation every time • Compact rack-mountable 19” 1U high enclosure features 8 channels with 4 outputs per channel • Real-time CCTV video at distances up to 1km (3,000ft) when used with any passive NVT transceiver or hub; 1,6km (1 mile) when used with the NV-653T active transmitter • RJ45 connectivity with optional RJ45-to-screw-terminal adaptors (included) • Exceptional interference rejection • Built-in transient protection and ground-lifting • Automatic compensation for reverse-polarity wiring • At-a-glance per-channel diagnostics • Compatible with qualified UTP cameras • Includes eight 60cm (2ft) coax jumper cables, rack mount hardware and two NV-RJ45A adaptors • Limited lifetime warranty TM Employing NVT’s latest generation DigitalEQ technology, the NV-872 is an 8-channel active (amplified) hub that allows the transmission of real-time monochrome or colour video for distances up to 1,6km (1 mile) using Category 5 or better unshielded twisted-pair (UTP) cable. The receiver hub continuously and automatically conditions the video signal, compensating for Cat5 UTP (or better) cable attenuation, wiring polarity, ground loops, and voltage transients, independent of video signal content. The unparalleled interference rejection and low emissions allow long run video to co-exist in the same cable bundle as telephone, datacom, or low-voltage power circuits. this allows the use of shared or existing Cat5 UTP (or better) cable plant. Ground-lifting ensures no annoying “hum-bars” when ground-potential differences exist. With built-in transient protection, damaging voltage spikes are eliminated. Network Video Technologies Ltd.
