When the doorbell camera 106 is fixed onto the surface, a lens assembly 704 of the doorbell camera 106 faces away from the surface for capturing images of a field of view i. e. , a camera scene, and a button top 706 sits on a front surface of the doorbell camera and receives a user press for activating a remote chime device. In some implementations, the device housing 702 is mechanically fixed onto the mounting plate 800 when a first fastener structure 806 located at a front surface of the mounting plate 800 is fastened to a second fastener structure 726 located at the rear exterior surface of the device housing 702. In a specific example, the first fastener structure 806 includes a snap fastener configured to lock onto the respective fastener structure 726 of the device housing 702. The mounting plate 800 may further include a first hole 908. The first hole 908 may be located on or in proximity to the raised edge of the mounting plate 800, allowing a release tool 912 to access the first hole 908 when a flat portion of the rear surface of the mounting plate 800 adheres to the mounting surface. The first hole 908 may be located on or in proximity to the first fastener structure 806. The release tool 912 may have an extended long apical part that fits into the first hole 908. The release tool 912 can be inserted into the first hole 908 to gain an access to the first fastener structure 806 or the second fastener structure 726 that mates with the first fastener structure 806 when the device housing 702 is mechanically fixed onto the mounting plate 800. The first fastener structure 806 and the second fastener structure 726 are unfastened from each other when the release tool 912 is inserted into the first hole 908 and applies an unlocking action e.
