Dahua DHI-ASR1200E is a professional RFID reader for access control systems, supporting two card standards simultaneously: Mifare at 13.56 MHz and EM-ID at 125 kHz. This allows the device to be used in mixed environments where different groups of employees or residents already have cards of different formats. The waterproof housing with surface mounting and triple light indication (red, blue, green LEDs) make the reader convenient for everyday operation. Data transmission via Wiegand 34/26 and RS-485 ensures broad compatibility with access controllers from Dahua and other manufacturers.
