Description
SPRO 4 Door 1-Way Access Controller – Smart Multi-Door Security Management
The SPRO 4 Door 1-Way Access Controller is a powerful central hub designed to manage and secure multiple entrances from one reliable system. Ideal for offices, warehouses, apartment buildings, and commercial properties, it allows you to control who can enter specific doors and when they can access them.
This controller can manage up to four doors from a single unit, making it a practical solution for sites that need organised and scalable access control. With support for up to 100,000 users, it’s suitable for both small businesses and larger buildings where many staff or residents require secure access.
The system supports multiple authentication methods, including access cards, PIN codes, fingerprints, and QR codes, giving you flexibility in how people enter your premises. This makes it easy to tailor access levels for employees, visitors, or residents.
Using the built-in web interface, the controller can be configured and managed directly from a standard web browser, allowing administrators to easily add users, adjust permissions, and review access records without needing complicated software.
The controller also records up to 500,000 access events, giving you a detailed history of who entered and when. This is particularly useful for security monitoring and site management.
Installation is simplified thanks to Power over Ethernet (PoE) support, allowing both power and network data to run through a single cable. The unit can also supply power to connected locks and card readers, helping reduce additional wiring and installation costs.
Designed to integrate with a wide range of access control hardware, the controller supports RS-485 and Wiegand readers, making it suitable for both new systems and upgrades to existing installations. It also includes fire alarm linkage, allowing doors to automatically respond in emergency situations.
Fully compatible with the SmartPSS Lite management platform, the SPRO 4 Door Controller provides a flexible and reliable solution for modern building security.
