Networked access control machines
Networked access control machines connect over a standard RJ45 LAN port or optional 4G cellular network, enabling remote management and multi-site control with or without fixed cabling. ZHONGYAN networked card readers support TCP/IP, UDP, HTTP and MQTT protocols in the same device, integrating directly into building management platforms, IoT systems and custom software through open API. Modbus gateway support extends compatibility to industrial and building automation controllers. Touch keypad models add PIN entry alongside card reading. Single-door and two-door configurations are available. The 4G version powers up and connects instantly without network wiring, suited to older buildings, retail units and temporary sites where cable installation is not practical. All units support remote unlock, user management and event logging. Custom hardware and firmware available on request. OEM and ODM, factory direct.
