The plurality of wire terminals 720 include a first terminal and a second terminal configured to receive a power supply line and a ground line for driving the plurality of electronic components contained within the device housing 106. Specifically, in an example, each of the power supply line and the ground line includes a respective fork terminal coupled to a corresponding wire terminal 720, and fixed thereto by tightening a screw fastener. Under some circumstances, the doorbell camera 106 is mounted on a wall or doorframe surface in place of a conventional doorbell, and the plurality of wire terminals 722 are coupled to receive the power supply line and the ground line that were applied to drive the conventional doorbell. Alternatively, in some implementations, the electrical connector 722 is coupled to one or more electrical wires for receiving a power supply or exchanging data with another electronic device. In an example, both the plurality of wire terminals 720 and the electrical connector 722 are available on the rear exterior surface of the device housing 702. The electrical connector 722 is only connected in a factory for testing, calibrating and/or setting up the doorbell camera 106, while the plurality of wire terminals 720 are applied to provide the power supply in the factory and/or after the doorbell camera 106 is shipped to a customer.
