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, continuous and automated visual monitoring of access control status can be performed.

After the camera is deployed at the entrance, OpenMV performs door-object recognition on-device 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.

When the door is detected to remain open for an extended period or is opened outside permitted hours, the system can instantly generate an alert on the edge device and trigger联动 with the access control system, operations and maintenance platform, or on-duty personnel to enable automated response.

Since the judgment logic runs directly on the camera’s edge side, the system operates stably and responds rapidly, making it highly suitable for scenarios demanding exceptional continuity and reliability—such as server rooms and power distribution rooms. OpenMV elevates infrastructure operations and maintenance from “manual inspection” to “continuous perception and proactive alerting.”
