Dahua DHI-ASC2204C-S — 4-Door Networked Access Controller
The Dahua DHI-ASC2204C-S is a 4-door, 1-way networked access controller with TCP/IP communication and dual protocol support. It is the central management panel in an access control system, storing credentials and making the access decisions for up to 4 doors.
Who is it for?
This is a controller, not a reader — it is installed as the panel behind the scenes and needs separate card or fingerprint readers wired to its Wiegand ports to actually identify people at the door. It suits installations needing centralised, networked control of up to 4 doors with large-capacity user, card and fingerprint storage.
