The SDC 705ULT is a networked access control processor designed for mid-to-large security deployments. It manages up to 63 doors and supports 250,000 user credentials, making it suitable for enterprise facilities, healthcare campuses, and distributed multi-building installations. The controller accepts multiple credential formats—DESFire, MIFARE, NFC/13.56MHz, and 125kHz proximity—enabling integration with existing card and mobile-based access systems.
Communicates via OSDP and TCP/IP protocols, supporting modern access control platforms and legacy system integration. Integrators can deploy across networked architectures without proprietary gateways. The 705ULT controller functions as a door processor in larger systems or as a standalone controller for multi-door facilities requiring credential encryption and centralized management.
