Abstract
Devices and techniques are generally described for a doorbell camera circuit architecture. In some examples, at least one processor of a doorbell device may generate a first control signal. The at least one processor may send the first control signal to a power-switching control circuit of the doorbell device. The power-switching control circuit may receive a first input electrical signal. The power-switching control circuit may store at least a portion of energy associated with the first input electrical signal in a plurality of capacitors of the power-switching control circuit. The power-switching control circuit may supply power from the plurality of capacitors to a camera of the doorbell device during a first state of the control signal. In various examples, the power-switching control circuit may supply power from the battery to the camera of the doorbell device during a second state of the control signal.
