How the eSSL Door Access Control System Operates
- ❶ Centralized Management: Admin registers credentials (cards, QR codes, passwords) into the eSSL Bio-CV Security web software. Define access rules: who can enter which door, during what time zone, and with anti-passback constraints.
- ❷ Reader Authentication: Reader sends card / QR code ID to C3-200 Plus controller via Wiegand or RS-485 protocol. The controller supports multiple authentication methods including RFID cards, dynamic QR codes, and passwords.
- ❸ Access Decision & Encryption: Controller instantly checks credential against database using AES 256-bit encryption for stored data. For controller-reader communication, AES 128-bit encryption secures the data exchange.
- ❹ Lock Activation: Upon approval, controller energizes the appropriate lock relay to grant entry. Built-in dry/wet mode support ensures compatibility with various lock types.
- ❺ Real-Time Monitoring & Logging: Every access attempt is logged in the 500,000-event buffer with timestamps. Administrators can monitor door status in real time via the web browser.
