, that of the wire 1016. Connector 1050C and 1050D are respectively coupled to the wires 1018 and 1020, and open wire ends of the connectors 1050C and 1050D are bent into a hook shape such that they may be fastened onto connectors on the doorbell chime 1006 directly. These connectors are compatible with existing wires 1014 and 1016 and the connectors of doorbell chime 1006, and ease the installation of the doorbell camera 106 without requiring the user to use additional tools. Referring to FIG. 10C, in some implementations, the doorbell camera 106 includes a voltage monitoring unit 1022 configured to generate the supply monitoring signal based on the input AC voltage. The LED indicator of the doorbell camera 106 is configured to, based on a value of the supply monitoring signal, display on a surface of the device housing 702 one of a set of predetermined visual patterns, thereby sending a visual message to a user of the doorbell camera 106 to indicate whether the input AC voltage is low with respect to the supply threshold. For example, the supply threshold may be 8V. When the input AC voltage is greater than 8V, the supply monitoring signal may control the LED indicator to display a green color along the peripheral edge 1040 of the doorbell button 1002, indicating that the input AC voltage is sufficient to drive the doorbell camera 106. In contrast, when the input AC voltage is not greater than 8V, the supply monitoring signal may control the LED indicator to display a red color along the peripheral edge 1040 of the doorbell button 1002, indicating that the input AC voltage is insufficient to drive the doorbell camera 106. Referring to FIG. 10D, in some implementations, the bypass unit 1012 may also function as a voltage meter to determine whether the transformer 1010 can provide a supply voltage sufficient to drive the doorbell camera 106 which normally consumes more power than a conventional doorbell.
