, mutes the remote chime 1006; conversely, at the time of a user press on the button 1002, the bypass unit 1012 provides the input AC voltage to drive both the remote chime 1006 and the camera module 1004. In some implementations, the doorbell camera 106 may include a rechargeable battery. In the second doorbell mode, the camera module 1004 of the doorbell camera 106 is electrically decoupled from the transformer 1010, and relies on the rechargeable battery e. g. , a battery 1116 in FIGS. 11A 11E to power the camera module 1004 when the button 706 is being pressed i. e. , at a second doorbell mode. The battery is recharged when the button 706 or the button 1002 is not pressed at the first camera mode. The battery is sized big enough so that it can charge back up in between button presses. Stated another way, the battery may be recharged between the button presses to reach a power level that is sufficient to sustain operation of the camera module 1004 during a subsequent press on the button 1002.
