A method for aligning a camera of a vehicle camera monitor system, wherein the camera is mounted to on one side of a vehicle with a cab and a trailer, wherein the camera is mounted to the cab and has a camera opening angle, the camera comprises at least one image sensor having an entire area, the entire area covering a full sensor field of view (FoV) comprising at least a first FoV legally-prescribed for a rear view device of the vehicle in form of class II FoV in a first area, the full sensor FoV is defined by the camera opening angle and the alignment of the camera relative to the vehicle, the class II FoV extending from an edge of said side of the vehicle, away from the vehicle, and the image data recorded by the at least one image sensor are forwarded to a monitor of the CMS to display an image comprising the first area to a driver of the vehicle, characterized by • aligning the camera with its camera opening angle such that the first area is arranged at the horizontal outermost position of the image captured by the image sensor of the camera and at the vertical outermost position of the image displayed on the monitor, wherein the entire area of full sensor FoV comprises two edge areas (12, 13) not meeting the sharpness requirements for the image on the monitor of the rear view device, and the first area is arranged directly next to a first edge area, • aligning the class IV FoV extending from the edge of said side of the vehicle, away from the vehicle, together with aligning the class II FoV such that a second area of the class IV FoV is displayed on the monitor, and • panning of the first area to a panned first area depending on the cornering situation of the vehicle, wherein o the first area is arranged in the upper right region of the monitor simulating a rear view mirror, and o the panned first area is arranged in the upper left region of the monitor simulating a rear view mirror. the camera is mounted to on one side of a vehicle with a cab and a trailer, wherein the camera is mounted to the cab and has a camera opening angle, the camera comprises at least one image sensor having an entire area, the entire area covering a full sensor field of view (FoV) comprising at least a first FoV legally-prescribed for a rear view device of the vehicle in form of class II FoV in a first area, the full sensor FoV is
