Low-power-consumption audio/video recording and communication doorbell
First Claim
1. A method for an audio/video (A/V) recording and communication doorbell system, the A/V recording and communication doorbell including a camera, a speaker, a microphone, a power manager, a battery, an AC/DC rectifier, and a DC/DC converter, wherein the A/V recording and communication doorbell is connected to an external AC power source through the AC/DC rectifier and the DC/DC converter, the method comprising:
- the power manager drawing power, up to a threshold power, from the AC power source, wherein the threshold power is measured at an output of the DC/DC converter; and
when the power drawn from the AC power source reaches the threshold power, the power manager drawing supplemental power from the battery such that the power drawn from the AC power source never exceeds the threshold power as measured at the output of the DC/DC converter.

Abstract
An audio/video (A/V) recording and communication doorbell, including a camera, a speaker, a microphone, a power manager, a battery, an AC/DC rectifier, and a DC/DC converter. The doorbell is configured for connection to an external AC power source through the AC/DC rectifier and the DC/DC converter. The power manager is configured to draw power, up to a threshold power, from the AC power source and to draw supplemental power from the battery such that the power drawn from the AC power source never exceeds the threshold power. The present A/V recording and communication doorbell can thus be connected to an existing household AC power supply and an existing doorbell signaling device without causing inadvertent sounding of the signaling device.
