Dahua DHI-ASR2101A-ME — Waterproof Card & Password Access Reader
The DHI-ASR2101A-ME adds a touch keypad to the same waterproof, dual-frequency reader platform as the ASR2100A-ME — card swipe or password unlock (or both, for two-factor access), IP66 rated, with RS-485 and Wiegand (W26/W34) outputs.
Who is it for?
Where card-only access isn't secure enough — or a backup unlock method is wanted if a card is lost or forgotten — the keypad adds a second credential type. Same outdoor-rated housing as the ASR2100A-ME, so it suits the same exposed door positions.
