The ZKTeco C3‑400 Plus is a high‑performance access control controller engineered for multi‑door security systems, supporting up to four access points with comprehensive authentication options including RFID card, password, and dynamic QR code. Built on a Linux operating system with a dedicated hardware platform, the C3‑400 Plus delivers reliable performance for medium‑sized enterprises and organizations in Pakistan looking for efficient centralized control of doors and secure entry policies.
With support for up to 100,000 users, 100,000 card credentials, and 100,000 QR code records, the controller offers substantial capacity and storage for large installations. It also holds up to 500,000 transaction logs for detailed auditing and reporting. Multiple communication interfaces including TCP/IP, RS‑485 (with OSDP support), Wiegand, and USB ensure flexible integration with ZKTeco readers as well as third‑party access devices. Standard security features like anti‑passback, anti‑tailgating, access levels, and holiday scheduling help enforce complex access rules.
