7B, in some implementations, a rear exterior surface of the device housing 702 provides an access to at least one of a plurality of wire terminals 720 and an electrical connector 722 e. g. , a Universal Serial Bus USB connector. 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. In some implementations, the rear exterior surface of the device housing 702 includes a plurality of recesses 724. For example, the plurality of wire terminals 720 is disposed within a first recess 724A, and separated by a separation 730 that protects the lines connected to the first and second terminals of the plurality of wire terminals 720 from being shorted to each other.

They had lots of potential but did not quite deliver. SkyBell HD on the other hand is a dramatic improvement and is still getting better. From the time this HD product hit the market there have already been updates to both the firmware and mobile application. These updates have improved functionality and reliability of the product itself and the new SkyBell HD application made it incredibly easy to interact with the product via multiple smartphone devices. Photo quality was drastically improved too true HD quality even with such a wide angle lens and colors are truly sharp regardless of night or day. The SkyBell HD app is a completely new app separate download in app store from the past models and is lightyears ahead and finally a “modern” app that works.
