A camera module for an occupant monitoring system is disclosed. The camera module includes a housing with an interior chamber and an aperture on one surface. An image sensor is position within the chamber and aligned with the aperture. A lens is positioned between the image sensor and the aperture along an optical axis to focus light entering the aperture onto the image sensor. To reflect light into the aperture from a field of view that is not along the optical axis, the camera module includes a planar reflector that extends at an angle from the surface of the housing and over the aperture.
