NVT : NV-653T
Description
The NVT Video Active Transmitter 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 better Unshielded Twisted-Pair (UTP) telephone wire.
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.
Features
NV-653T features include:
→ May share 24VAC power with camera, providing supply is floating
→ Up to ten NV-653Ts can be mounted to an NV-RM 8/10 Rackmount Pane
→ Full-motion CCTV video at distances up to 1 mile (1,6km) when used with active NVT receiver or hub
→ Exceptional interference rejection
→ Frequency Response DC to 10 MHz
→ Built-in transient protection and ground lifting
→ Three-position distance range switch
→ Blue power LED, green active LED
→ Up to ten NV-653Ts may be rack mounted using the NV-RM8/10 Rack Panel Kit
→ Limited lifetime warranty
