FIG. 10E is a flow chart of a method 1050 for controlling a
doorbell camera in accordance with some implementations. In some implementations, the method 1050 is implemented at the doorbell camera 106 having a doorbell housing 702 and a doorbell button 1002 mounted on a front cover plate 708 of the doorbell housing 702. The doorbell housing 702 contains a camera module, an LED indicator, a processor and memory including programs executed by the processor. The doorbell camera 106 is electrically coupled to 1052 a remote chime 1006 via a bypass unit 1012 powered by a transformer 1010 that provides an input AC voltage. The remote chime 1006 is configured to ring 1054 in response to a user press on the doorbell button 1002. A supply monitoring signal is generated 1056 by the doorbell camera 106 based on the input AC voltage to indicate whether the input AC voltage is greater than a supply threshold. Based on a value of the supply monitoring signal, a user is notified by the doorbell camera 106 as to whether there is sufficient voltage to power the doorbell. In accordance with the supply monitoring signal, a message is presented by the doorbell camera 106 to a user of the doorbell camera 106 to indicate whether the input AC voltage is low with respect to the supply threshold. In some implementations, the message may include a visual message
displayed by the LED indicator e. g.
