39. More details on the method 1500 implemented by the doorbell camera 106 are explained above with reference to FIG. 10C. Alternatively, in some implementations, at least part of the method 1050 may be implemented at the bypass unit 1012. Independently of whether the doorbell camera 106 is electrically coupled to the remote chime 1006 in place of a conventional doorbell, a supply monitoring voltage may be generated 1056 in the bypass unit 1012 based on the input AC voltage to indicate whether the input AC voltage is greater than a supply threshold. In accordance with the supply monitoring signal, a message may be presented 1058 by the bypass unit 1012 to a user of the doorbell camera 106 to indicate whether the input AC voltage is low with respect to the supply threshold. Optionally, the message may include a visual message displayed on the bypass unit 1012 by an LED indicator 1012B according to one of a set of predetermined visual patterns. In some implementations, the message presented to the user may include a ring of the remote chime 1006. By these means, voltage compatibility of the doorbell camera 106 may be determined and known to the user of the doorbell camera 106 before the doorbell camera 106 is installed, thereby avoiding installation of the doorbell camera 106 when it is not even compatible with the supply voltage provided by the transformer 1010. More details on the method 1500 implemented by the bypass unit 1012 are explained above with reference to FIG. 10D.
