168. , visible and infrared light passing through the transparent area 712. Further, in some implementations, the front cover plate 708 includes a microphone aperture 716, and a microphone 1104 is disposed under the front cover plate 708 and coupled to the microphone aperture 716 to receive sound wave entering the microphone aperture 716. In some implementations, the doorbell camera 106 further includes an ALS assembly 714 disposed under the cover glass 705 of the lens assembly 704. The ALS assembly 714 optionally includes a light pipe to direct light entering the lens assembly 704 to an ALS and ALS interface circuit that are optionally located with a distance from the lens assembly 704. In some implementations, the front cover plate 708 is substantially opaque except the button opening 710, the microphone aperture 716, and the camera opening or transparent area 712. In some implementations, the front cover plate 708 includes a substantially opaque area that is distinct from the button opening 710, the microphone aperture 716 and the camera opening or transparent area 712. The microphone 1104 is optionally concealed under the substantially opaque area. Further, in some implementations, an array of IR illuminators 1105 are disposed under the substantially opaque area of the front cover plate 708 and configured to illuminate a field of view of the lens assembly 704 with infrared light in a night mode. In an example, the array of IR illuminators 1105 include a number of e. g.
