AI Sentinel Based on OpenMV: Automatic Alert for Unsecured Key Locations

The door is not closed; any incident would constitute a “major accident.” Manual inspections cannot adequately cover the frequent changes in door status. OpenMV enables continuous system monitoring of the door’s status.

If the entrances to the equipment room, power distribution room, and residential units remain open for extended periods, safety incidents such as unauthorized entry, equipment damage, theft, or electric shock may occur, making this a high-risk area in operations and maintenance management.

Traditional methods primarily rely on manual inspections or access control log reviews, making it difficult to promptly detect frequent changes in door status, with issues often identified only after they occur.

Based on SingTown’s OpenMV smart camera, the access control status can be continuously and automatically monitored visually.

After the camera is deployed at the entrance, OpenMV performs door-object recognition on the edge side and analyzes the door panel’s angle, opening extent, and morphological changes to determine whether the door is closed, partially open, or fully open. Time-based rules can also be applied to distinguish between brief, normal openings and prolonged, abnormal openings.

The system can instantly generate alerts on the device side when a door remains open for an extended period or is opened outside of authorized hours, thereby triggering integrated responses with access control systems, operations and maintenance platforms, or on-duty personnel to enable automated handling.

Since the judgment logic runs directly on the camera’s edge side, the system operates stably and responds rapidly—making it highly suitable for environments such as server rooms and power distribution rooms, where continuity and reliability are critically required. OpenMV elevates infrastructure operations and maintenance from “manual inspections” to “continuous sensing and proactive alerts.”
