description A camera module includes a housing with an opening and a portion that surrounds the opening, wherein the portion of the housing is transparent to near infrared (NIR) light. A fisheye lens is disposed within the opening such that a portion of the fisheye lens protrudes through the opening. An image sensor is disposed within the housing and optically coupled to the fisheye lens. The image sensor is sensitive to visible light and NIR light. A plurality of NIR light emitters is disposed within the housing. The NIR light emitters are configured to emit NIR light through the NIR-transparent portion of the housing. The NIR-transparent portion of the housing may include a light-diffusing structure, such as a pattern of microlenses formed on an inner surface of the NIR-transparent portion of the housing, to spread out the NIR light emitted by the NIR light emitters.
