The Bioteknix InBio-460 Pro Plus is a four-door IP-based access control system designed to regulate and secure entry points in medium to large facilities. The system integrates multiple authentication methods, including fingerprint recognition, RFID cards, passwords, and dynamic QR codes, to verify user identity reliably. It supports centralized monitoring and management over TCP/IP and RS-485 networks, enabling real-time access control and event logging. With large storage capacity for users, biometric templates, and QR-code entries, the system can scale to accommodate offices, industrial complexes, and gated communities. Security is reinforced with AES-256 encryption for data storage and HTTPS/TLS 1.2 for communication, preventing unauthorized access and data breaches. Additional functionalities such as anti-passback, anti-tailgating, door interlock, and holiday scheduling enhance operational safety. The InBio-460 Pro Plus exemplifies modern access control theory by combining identification, authentication, networked management, and secure data handling in a scalable, reliable platform.
