Keri Systems NXT-2D Two Door and Four Reader Controller

The Keri Systems NXT-2D is a two-door, four-reader controller designed for modern IT environments. It connects directly to an existing TCP/IP network, eliminating the need for traditional cabling and reducing installation costs by up to 50% when using inexpensive CAT-5 cable.

With built-in Ethernet functionality and a proprietary MAC addressing scheme, the NXT-2D supports reliable hardware discovery and quick one-button autoconfiguration. It manages up to 48,000 cardholders and stores 10,000 events in its buffer.

The controller supports two doors and four readers, compatible with high-security 4-wire NXT Series proximity readers or Wiegand output devices via the NXT-RM3 Interface Module. The metal enclosure includes locking features, 128-bit encryption, and provides reassignable inputs and outputs with quick disconnect connectors.
