Access Controllers

Access controllers are the core components of an access control system, responsible for managing and verifying entry permissions for doors, gates, and secure areas. These controllers connect with various authentication devices such as facial recognition terminals, fingerprint readers, RFID card readers, and QR code scanners to determine whether access should be granted. YUNSHAO access controllers support multiple door configurations, including single-door, two-door, and four-door control, and typically communicate via TCP/IP or RS485 networks. They are widely used in office buildings, factories, residential communities, schools, and commercial facilities to provide centralized and reliable access management.
