An interior surface of the substantially opaque area is painted with
dark color ink e. g. , black ink. The dark color ink could be transparent to infrared light, such that the substantially opaque area is opaque to visible light and transparent to infrared light. In an example, the interior surface of the front cover plate 708 is entirely covered by the ink except the button opening 710 exposing the button top 706 and the substantially transparent area 712 covering the lens assembly 704. Further, in some implementations, the doorbell
camera 106 includes an array of IR illuminators not shown in FIGS. 7A and 7B. The IR illuminators can be disposed below any portion behind the substantially opaque area. The IR illuminators are concealed under the front cover plate 708, but light generated by the IR illuminators can still penetrate the front cover plate 708 to illuminate the field of view of the doorbell camera 106. In some implementations, the doorbell camera 106 further includes an ambient light sensor ALS assembly 714 at least partially disposed within the lens assembly 704. The ALS assembly 714 is configured to measure amount of light entering the lens assembly 702 from an ambient environment surrounding the lens assembly 704.
