AI Sentinel Based on OpenMV: Automatic Alert for Unlocked 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 even electric shock may occur, making this a high-risk area in operations and maintenance management.

The traditional approach relies primarily on manual inspections or access control log reviews, making it difficult to promptly detect frequent changes in door status, and issues are 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 deploying the camera at the entrance, OpenMV performs door-object detection 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 differentiate between brief, normal openings and prolonged, abnormal openings.

When the system detects that a door has remained open for an extended period or has been opened outside of authorized hours, it can instantly generate an alert on the edge device and trigger联动 with access control systems, operations and maintenance platforms, or on-duty personnel to enable automated response.

Since the decision-making 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 electrical distribution rooms, where continuity and reliability are critically required. OpenMV elevates infrastructure operations and maintenance from “manual inspections” to “continuous sensing and proactive alerts.”
