HOLDER BASE PART FOR SECURING AT LEAST ONE CAMERA HOUSING TO A VEHICLE PART OF A VEHICLE, CAMERA HOUSING AND CAMERA SYSTEM

A holder base part for securing at least one camera housing to a vehicle part of a vehicle, a camera housing and a camera system are described. The holder base part has a retaining element with a securing portion, by which the retaining element is secured to the vehicle part, and which has a retaining portion by which the retaining element is separably connected to a connection element on the side of the at least one camera housing by a sliding movement along a notional connection axis. The retaining portion contributes to defining an insertion region into which the housing-side connection element is inserted for separable connection to the retaining element. The retaining element has a holder-locking element which interacts with a housing-locking element on the side of the camera housing to lock a connection between the retaining element and the connection element. The holder-locking element is arranged in the insertion region.
