Soyal
Taiwan card/PIN controllers — the Hong Kong 工廈 door-access workhorse
Soyal (碩陽 / 茂旭) AR-series controllers are the systems already running in many Hong Kong industrial buildings and SME offices. Swan CCTV installs new AR-721H / AR-725-E / AR-837-E doors, expands existing RS-485 buses, and commissions 701ServerSQL / 701ClientSQL. Parts, EM/Mifare cards and AR-727-CM converters are locally available, so a failed reader can be swapped without ripping out the whole site.
