Dahua DHI-ASR2101A-ME - Waterproof IP66 Contactless Card Reader with Touch Keypad

Dahua DHI-ASR2101A-ME

The Dahua DHI-ASR2101A-ME is a waterproof access control card reader with a touch keypad. As a contactless card reader, it reads Mifare Classic 1K cards and ID cards on two frequencies and unlocks by card or password, then sends the information to an access controller for verification over RS-485 or Wiegand. It is a reader, not a controller, and works as part of an access control system. Dahua lists it for industrial zones, office buildings, schools, factories, stadiums, residential areas and government properties.

Also listed as ASR2101A-ME.

Common questions

Is the DHI-ASR2101A-ME an access controller?

No. It is an access control card reader that sends card or password information to an access controller for verification. It connects by RS-485 or Wiegand.

Which cards does it read?

Mifare Classic 1K cards at 13.56MHz and ID cards at 125kHz, with a card reading distance of 0 cm to 5 cm and a 0.1 s response time. If you need an ID card reader only, check your cards are 125kHz first.

Does it have a keypad?

Yes. Dahua lists a touch keypad for operation, so it supports card swiping, password, or multiple unlocking modes. It works as a door access keypad as well as a card reader, because the password you enter is sent to the access controller for verification.

Can I fit it outside?

It is IP66 rated for indoor and outdoor use, with an operating range of -30°C to +70°C and 5%RH to 95% non-condensing. Dahua notes that silicon sealant is needed, see the manual.

What power does it need?

12V 0.5A DC. Power consumption is 0.9W on standby and 1.7W when working.

Does it have tamper protection?

Yes. It has an anti-tampering alarm, and a built-in watchdog that detects abnormal operation and performs recovery.
