Model NV-3272 32-Channel Active Receiver Hub Front Rear RJ45A Adaptors Included Features: TM • Adaptive DigitalEQ fully automatic 4-band equalization provides adjustment-free equalization every time • Compact rack-mountable 19” 1U high enclosure features 32 channels with 1 output per channel • Full motion CCTV video at distances up to 3,000ft (1km) when used with any passive NVT transceiver or hub; 1 mile (1,6km) when used with the NV-653T active transmitter; 1,000ft (300m) with shielded twisted-pair when used with any passive NVT transceiver or hub • RJ45 connectivity with optional NV-RJ45A 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 thirty-two 2ft (60cm) coax jumper cables, rack mount hardware and eight NV-RJ45A adaptors • Limited lifetime warranty TM Employing NVT’s latest generation DigitalEQ technology, the NV-3272 is an 32-channel active (amplified) hub that allows the transmission of full-motion monochrome or color video for distances up to 1 mile (1,6km) using Category 2 or better unshielded twisted-pair (UTP) wire. The receiver hub continuously and automatically conditions the video signal, compensating for 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 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 spikes are eliminated.
