Keri Access Control

NetXtreme™, by Keri Systems begins with sophisticated SQL compliant software, operating in a true client/server environment. Feel free to enjoy multiple concurrent users, login across multiple concurrent sites, all accomplished without the imposition of third-party royalty fees. By all accounts, client/server applications have been deemed far superior to browser-based applications for security and information integrity. Still, you can count on NetXtreme™ for ease of use and administration, as the user interface has been designed around an extremely intuitive front-end.

Whether your application calls for dozens of operators or thousands of doors, Keri’s NetXtreme is the answer. Either of our two-door or four-door panels will handle 50K cardholders in resident memory. They can communicate seamlessly over your network or you may decide to create a new network utilizing simple CAT-5 cable. NXT-4D and NXT-2D panels are equipped with 4-pin block and RJ terminals for ease of connection. Once connected, an intuitive, one-button, auto-configuration process with embedded MAC address makes your setup a cinch.

  • Powerful user definable logical functions

The NXT-4D Xtreme 4 Door Controller is built for today’s IT environments. With all Ethernet functionality built directly into the controller, Keri’s proprietary MAC address allows for reliable hardware discovery and true 1 button autoconfiguration. Networking between NXT-4D controllers and/or its sister NXT-2D Xtreme 2 Door Controller also utilize peer to peer Ethernet standards. The NXT-4D is designed to be extremely intelligent with little reliance on network traffic for decision making allowing it to be extremely thrifty with any network’s valuable bandwidth.

To expand the system’s capabilities, up to four companion 4 x 4 Input/Output boards (NXT-4X4) can be added – one to each of the controller’s RS-485 trunks (busses). Customers can choose between Keri’s new line of highly secure, 4-wire NXT Proximity Readers with reader supervision, and any reader with a standard Wiegand output or Keri’s MS Series Proximity Readers via the NXT-RM Reader Interface Module. To manage the system, Doors NetXtreme software has much of the same look and feel as Keri’s acclaimed original DoorsTM software, but with the added functionality of Client/Server architecture.
