myQ Facility for commercial operations
myQ Facility, integrating with LiftMaster MAXUM door operators, provides real-time door monitoring from a centralized dashboard. It helps operations teams optimize door usage, reduce downtime, and respond quickly to issues.
Connecting commercial doors to myQ Facility lets you see and control access points from anywhere, review real-time data and analytics, and receive alerts when doors are open or when security risks appear.
