    Abstract: An audio/video (A/V) recording and communication doorbell device includes a transistor assembly and control circuitry. The transistor assembly is electrically coupled between an input power bus that distributes alternating current (AC) input power and/or direct current (DC) input power, and an output power bus that provides a DC output power for the A/V recording and communication doorbell device. The control circuitry is configured to cause the transistor assembly to convert AC input power and/or DC input power from the input power bus to the DC output power into the output power bus, to provide the DC output power for the A/V recording and communication doorbell device.

    Abstract: In implementations described herein, power is supplied to functional components of audio/video (A/V) recording and communication doorbell devices (“A/V doorbells”) during activation of signaling devices that are coupled to the A/V doorbells without the use of a backup power supply. To illustrate, systems described herein may include first parallel circuitry coupled to the signaling device and second parallel circuitry coupled to an A/V doorbell. The first parallel circuitry and the second parallel circuitry are configured to supply sufficient power to the functional components of the A/V doorbell during activation of the signaling device. In particular implementations, the first parallel circuitry and the second parallel circuitry include shunting circuitry to control the flow of current through the first and second parallel circuitry and supply sufficient power to both the signaling device and the A/V doorbell.

    Abstract: An audio/video (A/V) recording and communication doorbell device includes an input port, a switch, a first power supply, a second power supply, a button, a first controller, and a second controller. The switch is electrically coupled across the input port. The first power supply receives power from the input port and powers a first power supply rail, and the second power supply powers a second power supply rail. The button, when pressed, activates a signaling device. The first controller is at least partially powered from the first power supply rail and closes the switch in response to the button being pressed. The second controller is at least partially powered from the second power supply rail.
