Dahua DHI-ASR2201A — Mifare Card & Keypad Reader
The Dahua DHI-ASR2201A is a slim, waterproof access control card reader that combines Mifare Classic 1K (13.56MHz) card recognition with a touch keypad for PIN entry, connecting to a door access controller over RS-485 or Wiegand (W26/W34).
Who is it for?
The DHI-ASR2201A is a reader, not a standalone controller — it sits at the door and passes card or keypad credentials back to a separate Dahua access controller, which makes the actual lock decision. It suits installers adding or replacing entry readers on an existing Dahua access control system, anywhere a slim, IP66-rated unit is needed outdoors or in exposed locations.
