A camera apparatus is provided. A bracket is fixed to a windshield of a vehicle. A camera case is fixed to the bracket. A camera module is fixed to the camera case and includes a lens. A hood intercepts light. When the camera apparatus is fixed to the vehicle, an inclination angle of an optical axis of the lens with respect to the camera case is adjusted so that an object present ahead of the vehicle is captured within an angle of view of the camera module. The camera apparatus detects a position of the object. The object includes a lane and another vehicle. Information on the object is used for lane departure alarm control, light control, or collision avoidance control. The type of the inclination angle of the optical axis with respect to the camera case or the type of a shape of the hood is visually displayed.
