A device for monitoring occupants of seats in a passenger compartment of a vehicle, comprising:

• a heat sink divided into a plurality of sections, each of the sections comprising a base and a plurality of cooling fins, the bases extending along a common axis and defining a central niche therebetween, wherein the central niche is bordered by a cooling fin of each respective section;
• a plurality of unstructured light sources, each of the plurality of unstructured light sources attached to one of plurality of sections, wherein the fins of the heat sink protrude from the base in a direction opposite attachment points of the plurality of unstructured light sources;
• a plurality of structured light sources, each of the plurality of structured light sources attached to one of the plurality of sections and having an optical element for forming a structured light pattern, wherein the plurality of structured light sources are oriented along the common axis and at oblique angles to the central niche, such that the plurality of structured light patterns are non-overlapping and in combination, are directed such that they would cover all occupants of seats of the vehicle;
• and
• a camera attached to the niche and configured to capture image patterns resulting from distortion of the plurality of structured light patterns by the occupants of the seats, the camera is further configured to capture video images of an interior of said passenger compartment of the vehicle using illumination of said plurality of unstructured light sources;
• wherein the base of each section of the heat sink and the niche function as an optical bench for the camera and plurality of structured light sources.
