Dahua DHI-ASC2202B-S - 2-Door 1-Way Network Access Controller
The Dahua DHI-ASC2202B-S (Dahua lists it as ASC2202B-S, a 2 Door 1 Way Networked Access Controller) is a network access controller for door access control. It manages two doors in one direction over TCP/IP and takes up to 2 RS-485 and 2 Wiegand card readers. It holds 100,000 users and 3,000 fingerprints and stores 500,000 card swiping records. It is a controller, not a reader, so each door still needs its own reader and lock.
Also listed as ASC2202B-S.
