4-Channel Video Active Receiver

The NVT 4-Channel Video Active Receiver NV-452R is an active (amplified) device that allows the transmission of real-time monochrome or color video on up to 1 mile (1,6km) using Category Unshielded Twisted-Pair (UTP) telephone wire. The NV-452R provides signal conditioning in the form of ground lifting, distance EQ and transient protection.

The unparalleled interference rejection and low emissions of the Model NV-452R allow 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. The built-in sharpness and brightness controls compensate for cable loss.

NV-452R features include:

→ One floating power supply may power multiple NV-452R receivers
→ Two NV-452Rs can be mounted to an NV-RM 8/10 Rackmount Panel
→ Four active receiver channels in one product
→ Full-motion CCTV video at distances up to 3,000ft (1km) when used with any passive NVT transceiver; 1 mile (1,6km) when used with NV-653T transmitter
→ RJ45 or pluggable screw terminal connectivity
→ Exceptional interference rejection
→ Frequency Response DC to 10 MHz
→ Built-in transient protection and ground lifting
→ Built-in brightness and sharpness controls; blue power LED, green active LED
→ Compatible with qualified UTP cameras
→ Best choice for DVR and high resolution applications over 750ft (225m)
→ Two NV-452Rs may be rack mounted using the NV-RM8/10 Rack Panel Kit
→ Limited lifetime warranty
