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

The door is not closed; any incident that occurs 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, 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.

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 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 door-object detection on-device and determines whether the door is closed, partially open, or fully open by analysing the door panel’s angle, degree of opening, and morphological changes. Time-based rules can also be applied to distinguish between brief, normal openings and prolonged, abnormal openings.

The system can instantly generate alerts 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.

Since the decision-making logic runs directly on the camera’s edge device, the system operates stably and responds swiftly—making it highly suitable for environments with stringent requirements for continuity and reliability, such as server rooms and electrical distribution rooms. OpenMV elevates infrastructure operations and maintenance from “manual inspection” to “continuous sensing and proactive alerting.”
