AI Sentinel Based on OpenMV: Automatic Alert for Unattended 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 equipment rooms, power distribution rooms, 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, visual monitoring of access control status can be conducted continuously and automatically.

After the camera is deployed at the entrance, OpenMV performs door-object recognition 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 differentiate between brief, normal openings and prolonged, abnormal openings.

When the system detects that a door has remained open for an extended period or has been opened outside permitted hours, it 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 judgment logic runs directly on the camera’s edge side, the system operates stably and responds swiftly—making it highly suitable for scenarios with stringent requirements for continuity and reliability, such as server rooms and power distribution rooms. OpenMV elevates infrastructure operations and maintenance from “manual inspection” to “continuous sensing and proactive alerting.”
