The lens assembly 704 is concentric with a top one of the two semicircular ends, and the button top 706 is concentric with a bottom one of the two semicircular ends. Such physical arrangements not only create a more aesthetically pleasing look for the doorbell camera 106, but also ensure sufficient separation between the lens assembly 702 and the button top 706, thereby avoiding a user press on the button top 706 interfering with video recording of the camera module e. g. , by blocking the field of view of the lens assembly 704. The button top 706 is part of the button assembly, and is configured to receive the user press on the button assembly. The front cover plate 708 therefore includes a button opening 710 configured to expose the button top 706 of the button assembly on the front cover plate 708.
