In some implementations, the LED indicator is configured to illuminate through a peripheral edge 1040 of the doorbell button 1002 that surrounds the button top 702. 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. Stated another way, wires 1014 and 1016 that are used to couple the doorbell chime 1006 for the conventional doorbell are reconnected to the bypass unit 1012. The bypass unit 1012 has two additional wires 1018 and 1020 that are further connected to the remote chime 1006. In some implementations, the bypass unit 1012 is disposed in proximity to the remote chime 1006, i. e.
