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

The door is not closed; any incident that occurs would constitute a “major accident.” Manual inspections cannot adequately cover the frequent changes in door status. OpenMV enables the system to continuously monitor 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 electric shock may occur, making this a high-risk area in operations and maintenance management.

Traditional methods primarily rely 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 is possible.

After the camera is deployed at the entrance, OpenMV performs door-object recognition 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 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 of authorized hours, thereby triggering联动 with the access control system, operations and maintenance platform, or on-duty personnel to enable automated response.

Since the judgment logic runs directly on the camera’s edge side, 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 inspections” to “continuous sensing and proactive alerts.”
