Product Description
The Dahua ASR1200D is an IP65-rated RFID reader for access control installs where the reader sits outside or in wet/exposed locations. It's built slim for surface mounting on door frames and gate posts, with a flush-mount option also supported.
Interface and protocol
The ASR1200D talks RS485 or Wiegand — Wiegand 34 ships as the default, with Wiegand 26 also supported, so it drops into most existing controller wiring without a protocol mismatch on site.
Card frequencies
- 13.56MHz — Mifare card read support
- 125KHz — EM-ID card read support
Running both frequencies means the same reader head handles a mixed card estate without swapping hardware.
Build and diagnostics
- IP65 water-proof rating — suited to exterior doors and weather-exposed access points
- Red and blue LED status indicators (plus green LED per the on-pack spec)
- Built-in buzzer for audible feedback at the door
- Watchdog function to guard against the reader halting in service
For integrators standardising on Dahua access hardware, the ASR1200D pairs with RS485 or Wiegand-based controllers already on the panel schedule — check your controller's Wiegand bit-length setting (26 vs 34) before wiring in.
