ABSTRACT:
A camera unit for monitoring a spatial region has an electronic image sensor arranged on a component carrier, and a lens having a lens body. The lens body and the component carrier are connected via a first coupling piece to form an integrated structural unit. The first coupling piece has at least one limited first mobility relative to the lens body and at least one limited second mobility relative to the component carrier within the integrated structural unit. The integrated structural unit has at least one first and one second releasable clamping mechanism in order to fix the first coupling piece, the lens body and the component carrier relative to one another. Such a camera unit can advantageously be used as an imaging sensor for safeguarding a machine operating in an automated fashion.
