A terminal apparatus transmits, to a server, setting information including specification information of a camera based on input manipulation of the user, environment information indicating an environment in which the camera is installed, and a map image of a place where the camera is installed. The server calculates a capturing area of the camera in the map image, places a subject model that serves as a capturing target of the camera at a prescribed position in the capturing area and generates a synthesized image, generates a face image and a whole body image of the subject model located at the prescribed position that is inferred to be captured by the camera, transmits the synthesized image and the face image and the whole body image of the subject model to the terminal apparatus. The terminal apparatus displays the synthesized image, the face image and the whole body image of the subject model.
