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.

Abstract: Audio/video (A/V) recording and communication devices according to the present embodiments comprise a processor, a motion sensor, and a camera. In various embodiments, the A/V recording and communication devices are configured to reduce latency and/or to reduce false positive indications of motion.
