BiomaxID MID-D4 is a 4-door access control panel designed for centralized management of entry points in office buildings, factories, and gated communities. This network-ready controller supports TCP/IP and RS485 communication, enabling real-time monitoring and remote access control for up to four independent doors.
The MID-D4 integrates seamlessly with BiomaxID face recognition terminals (MID seria) as well as third-party RFID readers and keypads. It features standard Wiegand input/output (WG26/34), electric lock relays, exit button inputs, and door contact sensors — providing a complete hardware foundation for enterprise-grade security systems.
With 30,000 user capacity, this 4-door access controller supports anti-passback, interlocking, and time zone scheduling. The free SDK allows custom integration with third-party software, while the onboard web server enables direct configuration without additional software. Designed for 24/7 continuous operation, the MID-D4 delivers reliable door control for small to mid-sized installations.
