Abstract

Each of cameras generates a background image of an imaging region captured by the camera, extracts moving information regarding a staying position or a passing position of a moving object in the imaging region of the camera, and transmits the background image and moving information of the moving object in a specific period to a server in response to a transmission request from the server or an input device. In a case where a first moving information analysis image in which moving information of a moving object in an imaging region of a first camera is superimposed on the background image transmitted from the first camera among the plurality of cameras is generated and displayed on a monitor, the server generates a second moving information analysis image in which moving information of a moving object in an imaging region of a second camera is superimposed on the background image transmitted from the second camera which is different from the first camera in response to a camera switching operation, and displays the second moving information analysis image on the monitor.

generate a first moving information analysis image in which moving information indicating a passing position of a plurality of moving objects in an imaging region of a first camera is superimposed on the background image downloaded from the first camera among the plurality of cameras, and to display the first moving information analysis image on a monitor,

to generate a second moving information analysis image in which moving information indicating a passing position of a plurality of moving objects in an imaging region of a second camera is superimposed on the background image downloaded from the second camera which is different from the first camera among the plurality of cameras in response to a camera switching operation, and to display the second moving information analysis image on the monitor,

generate a plurality of camera selection buttons respectively corresponding to the plurality of cameras,

cause the plurality of camera selection buttons respectively corresponding to the plurality of cameras to be displayed on the monitor when the first moving information analysis image or the second moving information analysis image is displayed on the monitor, each displayed camera selection button of the plurality of camera selection buttons corresponding to a camera having respective background image and moving information downloaded from the camera to the server,

receiving, from a user, a selection of a camera selection button from the plurality of camera selection buttons, and
