NXT-2D Keri Systems 2 Door/4 Reader NXT Controller with Enclosure

The NXT-2D Controller is built for today’s IT environments. By using an existing TCP/IP network, controller cabling costs can be eliminated. Or, if building a new network, they can be reduced up to 50% over traditional hard-wired access systems by using inexpensive, CAT-5 cable. The NXT-2D is designed to be extremely intelligent with little reliance on network traffic for decision making, allowing it to be thrifty with any network’s valuable bandwidth.
