Dahua Double Door two-way Access Controller

Get right-sized access control without compromise with the 2-Door 2-Way Networked Access Controller from Communicate Systems. Managing two doors with full two-way entry and exit control, this web-based unit is administered straight from a browser on any networked PC — ideal for offices, clinics, retail sites, and smaller facilities that want serious security without a sprawling system.

Compact on the outside, enterprise-grade on the inside: the controller holds 100,000 users, 100,000 passwords, 100,000 cards, and 10,000 fingerprints, and logs up to 500,000 access records — capacity that will outlast your growth plans while preserving a detailed history of every movement through your doors.

Connecting your devices is straightforward, with 5 × RS485 ports and 4 × Wiegand ports ready to accept everything from modern biometric readers to existing legacy card readers, protecting the investment you’ve already made in access hardware.

It also keeps watch beyond the door. Four alarm input channels and four alarm output channels let you wire in door contacts, sirens, and strobes, or link to third-party alarm equipment, so the controller sits at the centre of a joined-up security response.
