A camera includes a camera housing with a housing wall demarcating the interior of the camera housing, an optical aperture and a lenslet aperture extending through the housing wall, and an opaque blocking wall adjoined to and extending inwardly from the housing wall and circumscribing the lenslet aperture; a lenslet in the lenslet aperture aligned with an on-camera light source; a lens contained within the camera housing and aligned with the optical aperture to receive light entering the camera housing through the optical aperture; an imager within the camera housing and aligned with the lens to capture light passing through the lens; and circuitry contained within the camera housing communicative with the imager and operable to operate the camera. The circuitry includes a printed circuit board that abuts the opaque blocking wall and on which is mounted a light source positioned to be circumscribed by the opaque blocking wall.
