The doorbell camera 106 is electrically coupled to the remote chime 1006 via a bypass unit 1012 powered by a transformer 1010 that provides an input AC voltage e. g. , by converting a mains power supply of 110V to the input AC voltage of 8V, 10V or 12V. The remote chime 1006 is configured to ring in response to a press on the doorbell button 1002. In some circumstances, a conventional doorbell is electrically coupled to the remote chime 1006 that is further coupled to the transformer 1010. When the doorbell camera 106 replaces the conventional doorbell, the remote chime 1006 is disconnected from the transformer 1010 and the doorbell, and replaced by the bypass unit 1010.
