Abstract: A video doorbell device comprises a main unit with an output device such as a speaker and sensors such as a camera and microphone, as well as a faceplate interface. The faceplate interface includes mechanical and electrical connections. Faceplate accessories may be changed by a user to provide different functionality as needed. A faceplate accessory that is connected to the interface may exchange information with the main unit via the electrical connections. Different faceplate accessories may provide specialized input buttons, additional sensors, area illumination, display devices to show customized messages, and so forth. Some faceplate accessories provide enhanced access control functionality by providing a keypad, fingerprint sensor, or a near-field communication (NFC) interface, and so forth. Communications between the faceplate accessories and the main unit may be secured. The main unit may also detect installation and removal of a faceplate accessory.

Abstract: A device includes a housing, a camera at least partially disposed within the housing, one or more microphones at least partially disposed within the housing, and a printed circuit board (PCB) including a switch. The switch has a lever that is transitionable between a displaced position and a non-displaced position. A privacy cover couple to the housing and includes a rib disposed on an interior surface of the privacy cover. The privacy cover is transitionable between a first position in which the camera is obstructed and the rib is engaged with the lever to transition the lever to the displaced position, and a second position in which the camera is unobstructed and the rib is disengaged with the lever such that the lever is permitted to transition to the non-displaced position.
