The power supply and ground lines come out of the surface, pass through the opening 810, and are connected to the plurality of wire terminals 720 located at the rear exterior surface of the doorbell camera 106. The device housing 702 is then mounted onto the mounting plate 800 via the fasteners 806 and 808 and their respective fasteners 726 and 728 located at the rear exterior surface of the doorbell camera 106. The power supply and ground lines are concealed within the opening 810 of the mounting plate 800 and the first recess 724A of the device housing 702. Under these circumstances, the depth of the first recess 724A is configured such that a cumulative depth that sums the depth of the first recess 724A and a depth of the opening 810 is greater than a height of connections formed between the plurality of wire terminals 720 and the power supply and ground lines. By these means, the device housing 720 may be securely mounted onto the mounting plate 800 without being withheld by the connections formed between the plurality of wire terminals 720 and the power supply and ground lines.
