Access Control Issues With Gate Installs



• The NVT Model NV-214A-M Video Transceiver is a passive (non-amplified) device that allows the transmission of real-time monochrome or color video over Unshielded Twisted-Pair (UTP) telephone wire. Baseband (composite) signals of any type are supported.
Up-the-coax type signal may be sent over the same wire pair. The NV–214A–M is a transceiver and designed to be used at both camera and receiver end of the system. Used as a transmitter, the NV–214A–M has a mini-coax pigtail lead which allows quick mounting onto fixed cameras and allows in-camera mounting in most dome cameras.


The unparalleled interference rejection and low emissions of the Model NV-214A-M allow video signals to co-exist in the same wire bundle as telephone, datacom, or low-voltage power circuits. This allows the use of a shared or existing cable plant. With built-in transient protection, damaging voltage spike problems are eliminated.


• The NVT Model NV-452R Video Receiver is an active (amplified) device that allows the reception of real-time monochrome or color video on up to one mile (1,6km) using Category 2 or 3 Unshielded Twisted-Pair (UTP) telephone wire, or up to 1.5 miles (2,4km) using Category 5. With the Model NV-452R long run video signals can 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.
