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

The door is not closed; any incident would constitute a “major incident”. 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 server room, electrical distribution room, and residential units remain open for extended periods, safety incidents such as unauthorised entry, equipment damage, theft, or even 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 only identified 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 detection on-device 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 differentiate between brief, normal openings and prolonged, abnormal openings.

When the system detects that a door remains open for an extended period or is opened outside permitted 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.

As the decision-making logic runs directly on the camera’s edge device, the system operates stably and responds swiftly—making it highly suitable for mission-critical environments such as server rooms and electrical distribution rooms, where continuity and reliability are paramount. OpenMV elevates infrastructure operations and maintenance from “manual inspections” to “continuous sensing and proactive alerts.”
