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

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

Based on SingTown’s OpenMV smart camera, continuous and automated visual monitoring of access control status can be performed.

After deployment at the entrance, OpenMV performs on-device door-object recognition and analyses the door panel’s angle, degree of opening, 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 to be opened outside permitted hours, the system can instantly generate an alert on the edge device and trigger integrated responses with the access control system, operations and maintenance platform, or on-duty personnel to enable automated handling.

As the decision-making logic runs directly on the camera’s edge device, 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 critical. OpenMV elevates infrastructure operations and maintenance from “manual inspections” to “continuous sensing and proactive alerts.”
