Let AI vision with OpenMV automatically determine whether a mask is worn, eliminating the need for manual monitoring.

In public places with high personnel turnover, whether masks are worn correctly directly affects on-site order and management efficiency. Relying solely on manual monitoring is not only costly but also difficult to ensure timely coverage of all entrances. OpenMV moves the judgment of “whether a mask is properly worn” to the on-site location, enabling more timely and stable management.

In key areas such as public places, entrances and exits of parks, hospitals, and transportation hubs, whether personnel wear masks correctly directly affects on-site order management and the efficiency of safety regulation enforcement.

Traditional methods primarily rely on manual monitoring or post-event review of surveillance footage, resulting in high labor costs and difficulty in timely intervention. Some cloud-based video analytics solutions also suffer from issues such as strong network dependency, high latency, and privacy risks. Leveraging SingTown’s OpenMV intelligent camera, the system performs real-time mask-wearing status recognition at the camera edge, shifting judgment, decision-making, and control to the site to achieve true “instant perception and instant response.”

OpenMV is typically installed above entry/exit gates, passageways, or critical areas to capture frontal or semi-profile images of individuals entering.

The camera runs a facial detection algorithm on the edge device to automatically locate facial regions and further perform feature extraction and structural analysis on key areas such as the mouth and nose. By integrating an edge-side AI classification model, it accurately distinguishes among multiple states including not wearing a mask, wearing a mask improperly (exposed nose or mouth), and wearing a mask correctly.

When the system detects a violation, OpenMV can directly trigger voice prompt devices, access control systems, or local alarm modules via GPIO or serial interfaces, enabling “instant notification upon identification” and “immediate interception upon violation” without manual intervention.

Leveraging OpenMV’s on-device AI and edge computing architecture, the recognition process does not require uploading video data to the cloud—ensuring millisecond-level response times, significantly reducing network and server costs, and safeguarding personnel privacy at the source. This upgrades mask management from “manual supervision” to an intelligent mode of “automatic sensing + automatic execution.”
