g. , by the bypass circuit 1012C while coupling the camera module 1004 of the doorbell camera 106 to the transformer 1010 to receive power therefrom. It is noted that when the remote chime 1006 is bypassed, the remote chime 1006 is electrically coupled to the bypass unit 1012 and the transformer 1010 while still letting pass a substantially low current that is less than a threshold chime current and does not activate the remote chime 1006 to ring. In addition, the bypass unit 1012 is configured to operate in the second doorbell mode in accordance with a determination that a user press has been applied to the button. In the second doorbell mode, the bypass unit 1012 enables the remote chime 1006 to ring while coupling the doorbell camera 106 to the transformer 1010 e. g.
