The new Mercury MP Intelligent Controllers provide a bridge between today’s urgent security needs and tomorrow’s emerging realities. Featuring Secure world processing within a trusted execution environment and a future-ready, on-device application environment to drive advanced enterprise strategies with sophisticated programs and analytics adjacent to the door. With unmatched cybersecurity, robust reliability, and an open architecture, the MP controller infrastructure is ready for the challenges of today and well into the future.

The MP4502 supports 2 million cardholder records and a variety of extended features including High Assurance Credential Authentication (pending firmware update) and complies with the BACnet/IP communication protocol. A USB-to-Ethernet IP adapter provides a redundant host IP connection. It has direct hardware support for two openings and can scale to 64 access points. Built on proven Mercury hardware, this high-performance intelligent controller embeds elevator destination dispatch and provides integrated power management analytics to proactively detect failure before it occurs.

Built on the Mercury platform, the intelligent controller can connect to cloud or server-based hosts and can operate independently to perform access control functions. The development environment allows partners to enhance their solutions with custom applications; applications can be loaded directly onto a controller for scalable, modern integrations.

For partners seeking an empowering, comprehensive and open access control platform that is also reliable and cybersecure, the MP4502 is the clear solution. It delivers a complete security and access control solution, an innovative edge processing and development environment, interoperability and data security.
