monitored burglar alarm
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. FIGS. 11A and 11B include a top view 1100 and a cross sectional view 1140 of a doorbell camera 106 in accordance with some implementations, respectively, and FIGS. 11C 11E are three exploded views of a doorbell camera 106 in accordance with some implementations. FIGS. 11F and 11G are a front side and a rear side of a secondary board 1112 in accordance with some implementations.
