Dahua DHI-ASR1200E-D – 125kHz RFID Access Control Reader IP66 for Security Systems

The Dahua DHI-ASR1200E-D is an RFID card reader for access control, compatible with 125 kHz EM-ID and 13.56 MHz Mifare technologies, designed for access points in office buildings, industrial facilities, and secured sites requiring card-based identification with environmental protection. Widely used as an outdoor access reader or in humidity-exposed areas, the IP66-rated weatherproof enclosure ensures reliable operation under demanding weather conditions.

Dual support for EM-ID 125 kHz and Mifare 13.56 MHz cards provides broad compatibility with existing access control infrastructures without replacing cards or the management system. The Wiegand 34-bit interface (with optional Wiegand 26) and RS-485 protocol enable flexible integration into Dahua access controllers and compatible multi-vendor systems. Three-color LED indicators — red, blue, and green — provide clear visual feedback to operators and users at each access event.

The surface-mount design simplifies installation on doors, turnstiles, and barriers without special infrastructure requirements. The IP66-rated enclosure withstands direct water jets and dust ingress, suitable for both indoor installation in wet areas and outdoor mounting across varied climatic conditions. The reader integrates natively into the Dahua Access Control ecosystem alongside ASC controllers and centralized management modules.

Recommended for physical security system integrators deploying access control in office buildings, parking facilities, industrial sites, warehouses, and secured perimeters where IP66 environmental protection and dual-frequency RFID compatibility are baseline project requirements. The DHI-ASR1200E-D is the appropriate reader for exposed access points where reliability under harsh conditions is the primary selection criterion.
