SpotCam Doorbell takes an opposite approach from most video doorbells, with its large button enclosure and a tiny ringer. The enclosure holds the 4 AA batteries that power the device, while the tiny ringer is no bigger

The power supply connector 11082 is electrically coupled to the plurality of wire terminals 720, and configured to receive an external power supply. The AC DC converter 11084 is coupled to the power supply connector 11082 and configured to generate one or more DC supply voltages to drive various electronic components of the
doorbell camera 106. The voltage regulator 11086 is configured to regulate the one or more DC supply voltages to one or more internal supply voltages as needed. The power unit 11088 is coupled to the image sensor array 1114 and/or the image processor to provide power therefor. In some implementations, the sensor board 1108 further
