## Long description

Dahua Technology DHI-ASR1100B-V1 RFID reader RS-485/Wiegand Black is an access control card reader designed to interface with standard access controllers. The reader supports MIFARE 13.56 MHz cards and transmits card data via Wiegand or RS-485 protocols. Its compact surface-mounted housing (72 mm wide, 102 mm deep, 18 mm high) and IP67-rated enclosure make it suitable for indoor and outdoor installation where durable, tamper-aware card reading is required.
Advantages
The reader provides flexible communication options through both Wiegand and RS-485 interfaces, enabling integration with a wide range of access control systems. IP67 ingress protection and a waterproof design allow reliable operation in harsh weather conditions. Built-in tamper detection (Watch Dog) enhances physical security by alerting the controller in case of interference, while red and green indicator LEDs offer immediate visual status feedback for users. The surface-mounted form factor simplifies installation on walls or panels.
