  • Publication number: 20230236601
    Abstract: A control system is configured to control a system including a plurality of cameras installed in a facility, and perform a group classification process for recognizing a feature of a person photographed by the camera and classifying the person into a predetermined first or second group based on the feature. When there is or isn’t a person belonging to the first group, the control system selects a first operation mode and a second operation mode different from the first operation mode, respectively. When the control system selects the second operation mode, it performs the process so as to make either one of the number of cameras to be operated among the plurality of cameras and the number of cameras used as an information source in classification in the process among the plurality of cameras less than the number of cameras that are used when the first operation mode is selected.
