Dahua DHI-ASR2100A-ME — Waterproof Dual Frequency Card Reader
The DHI-ASR2100A-ME is an IP66 waterproof card reader supporting dual-frequency reading — Mifare Classic 1K (13.56MHz) and ID cards (125KHz) — with RS-485 and Wiegand 34 protocol outputs to a compatible access controller.
Who is it for?
The IP66 rating suits outdoor or exposed door positions — external gates, car parks, loading bays — where a standard indoor reader wouldn't survive. Pairs with a Dahua access controller such as the ASC2204B-S via RS-485 or Wiegand.
