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

The door is not closed; any incident that occurs would constitute a “major incident”. Manual inspections struggle to keep up with the frequent changes in door status. OpenMV enables continuous system monitoring of the door’s status.

If the entrances to the server room, power 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 rely primarily 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 the fact.

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

After deployment at the entrance, OpenMV performs on-device door-object detection 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.

The system can instantly generate an alert on the device side when a door remains open for an extended period or is opened outside permitted hours, thereby triggering integrated responses with access control systems, operations and maintenance platforms, 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 electrical distribution rooms—locations where continuity and reliability are critically important. OpenMV elevates infrastructure operations and maintenance from “manual inspections” to “continuous sensing and proactive alerts.”
