The ZKTeco C3 Pro Plus central controller is an IP-based access control solution that supports RFID cards and dynamic QR code authentication. The C3 Pro Plus series includes three models: C3-100 Pro Plus, C3-200 Pro Plus, and C3-400 Pro Plus, designed specifically for small and medium-sized enterprises, with the ability to manage up to 100,000 multi-technology card users and 100,000 dynamic QR code transactions.
The ZKTeco C3 Pro Plus central controller has an RS-485 interface, supporting ZKTeco’s RS-485 protocol and OSDP (version 2.1.7), ensuring flexible access with card readers. The system is also compatible with ZKTeco’s QR code readers such as QR50, QR500, and QR600. The series integrates seamlessly with third-party access control readers via the Wiegand interface (W26/W34/W66).
For enhanced security, the C3 Pro Plus uses AES 256-bit encryption for data storage. The system also adopts AES 128-bit encryption to protect secure communication between the controller, readers and I/O expansion boards. In addition, the ZKTeco C3 Pro Plus supports HTTPS/TLS1.2 protocol, ensuring maximum security in information transmission between the server and web client.
