Time dictates its own rules in 2020. COVID-19 provoked the need for a mass regime of facial masks and the introduction of appropriate restrictions. On a daily basis, most organizations do not cope with the physical control of staff and visitors, which leads to violations of the established rules and restrictions. The technology of face masks detection in the intelligent video surveillance system allows you to determine in real-time the presence of a mask on the face of each passing person, exclude the facts of ignoring the mask mode, check the correctness of wearing face masks and notify of violations. Incorrectly put on the mask reduces the confidence level of the mask detection, which allows you to adjust the level of control of the mask regulation.
