The SPRO 4 Door 1-Way Access Controller is a powerful and scalable access control solution designed for multi-door security management in commercial and industrial environments. Built on a stable Linux operating system, it features an embedded web interface that allows simple configuration and system management through a standard web browser.

With support for up to 100,000 users, cards, and passwords, as well as 10,000 fingerprints and storage for up to 500,000 access records, the controller is well suited for high-traffic sites requiring large user capacity and reliable data processing. Multiple authentication methods are supported, including card, password, fingerprint, and QR code, providing flexible access options. Time-based unlock schedules can be configured to meet operational and security requirements.

The controller supports RS-485 and Wiegand card readers, ensuring broad compatibility with existing access control hardware. It is capable of supplying power simultaneously to multiple devices, four locks (AC-DC-41), as well as up to four card readers, helping to simplify wiring and reduce installation costs.

For enhanced safety and system integration, the SPRO 4 Door 1-Way Access Controller supports fire alarm linkage. Network connectivity is provided via TCP/IP, with support for automatic registration, P2P connectivity, and DHCP. Power over Ethernet (PoE) further simplifies deployment by combining power and data transmission over a single network cable.

Fully compatible with the SmartPSS Lite management platform, this controller delivers a reliable, flexible, and easy-to-manage access control solution for modern security systems.
