A camera system for a vehicle includes: a camera housing; an imager module accommodated in the camera housing, the imager module including a carrier device, a lens accommodated in the carrier device, and an image sensor accommodated at the carrier device, an optical axis of the camera system being set by the image sensor and the lens. The image sensor makes contact with a metallic housing part of the camera housing via a heat-conducting element. The imager module is fixed in one direction perpendicular to the optical axis in the camera housing, i.e., it is braced in the radial direction and cooled axially toward the rear.
