In the low power mode, the images are optionally captured and/or transmitted to the server at a lower resolution and a lower frame rate, and local image processing may be disabled to conserver power. In some implementations, the doorbell camera 106 alternates between a first camera mode and a second doorbell mode during its normal operation. The bypass unit 1012 is configured to operate in the first camera mode when it is determined that no user press has been applied to the button. Specifically, during the first camera mode, the bypass unit 1012 bypasses the remote chime 1006 e. 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.
