The present disclosure refers to a rear view system for a vehicle, comprising a rear view device comprising at least one camera module and/or at least one reflective element, wherein the rear view device is configured to be mounted to the vehicle, in particular to a door or a body of the vehicle, in order to capture a field-of-view (FOV) in a scenery at least around a rear part of the vehicle and to be moved between at least two states relative to the door and/or the body of the vehicle, in particular between a folded and unfolded state, characterized by a time-of-flight (ToF) sensor for emitting at least one light signal, and a processing unit for determining at least one of the states of the rear view device when the rear view device is mounted to the vehicle, wherein the ToF sensor is configured to be mounted to the rear view device or to the vehicle separate from the rear view device, and wherein the processing unit is configured to operate the ToF sensor to emit the at least one light signal towards the FoV of the rear view device in case the ToF sensor is mounted to the rear view device or towards the rear view device in case the ToF sensor is mounted separate from the rear view device and to determine the at least one state of the rear view device based on the at least one light signal. It also refers to a vehicle with such a rear view system.
