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.

First claim

What is claimed is:

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 button, and a means for diverting power, wherein the A/V recording and communication doorbell is connected to an external power source, the method comprising:
the A/V recording and communication doorbell drawing power from the power source;
the power flowing through a signaling device and the power diverting means connected in parallel with the signaling device, wherein the power diverting means is in a low impedance state; and
when the button is depressed, the power diverting means transitioning to a high impedance state, thereby diverting power from the power source through the signaling device to cause the signaling device to emit a sound.

2. The method of claim 1 , wherein the signaling device is electro-mechanical or electronic.

3. The method of claim 1 , wherein the signaling device is external to the A/V recording and communication doorbell.

4. The method of claim 1 , wherein the A/V recording and communication doorbell further includes a timer, wherein when the button is depressed the timer is activated and the power diverting means remains in the high impedance state until the timer expires, unless the A/V recording and communication doorbell receives a notification that a call to a client device has been answered.

5. The method of claim 4 , further comprising the power diverting means transitioning to the low impedance state when the A/V recording and communication doorbell receives the notification that the call to the client device has been answered.

6. The method of claim 4 , wherein the timer is a first timer and the A/V recording and communication doorbell further includes a second timer, the method further comprising the power diverting means transitioning to the low impedance state, the second timer being activated when the power diverting means transitions to the low impedance state, and the power diverting means being prevented from again transitioning to the high impedance state until after the second timer expires.

7. The method of claim 1 , further comprising the A/V recording and communication doorbell, in response to the button being depressed, sending an alert signal and a video signal to a network device, the video signal including images captured by the camera.

8. An audio/video (A/V) recording and communication doorbell system, comprising:
an A/V recording and communication doorbell including a camera, a speaker, a microphone, a button, and a power diverting means, wherein the A/V recording and communication doorbell is connected to an external power source;
wherein the A/V recording and communication doorbell is configured to draw power from the power source such that the power flows through a signaling device and the power diverting means in parallel with the signaling device when the power diverting means is in a low impedance state; and
when the button is depressed, the power diverting means is configured to transition to a high impedance state thereby diverting power from the power source through the signaling device to cause the signaling device to emit a sound.

9. The A/V recording and communication doorbell system of claim 8 , wherein the signaling device is electro-mechanical or electronic.

10. The A/V recording and communication doorbell system of claim 8 , wherein the signaling device is external to the A/V recording and communication doorbell.

11. The A/V recording and communication doorbell system of claim 8 , wherein the A/V recording and communication doorbell further includes a timer, wherein the A/V recording and communication doorbell is further configured such that when the button is depressed the timer is activated and the power diverting means remains in the high impedance state until the timer expires, unless the A/V recording and communication doorbell receives a notification that a call to a client device has been answered.

12. The A/V recording and communication doorbell system of claim 11 , wherein the power diverting means is configured to transition to the low impedance state when the A/V recording and communication doorbell receives the notification that the call to the client device has been answered.

13. The A/V recording and communication doorbell system of claim 11 , wherein the timer is a first timer and the A/V recording and communication doorbell further includes a second timer, wherein the A/V recording and communication doorbell is further configured such that when the power diverting means transitions to the low impedance state, the second timer is activated and the power diverting means is prevented from again transitioning to the high impedance state until after the second timer expires.

14. The A/V recording and communication doorbell system of claim 8 , wherein the A/V recording and communication doorbell is further configured to send, in response to the button being depressed, an alert signal and a video signal to a network device, the video signal including images captured by the camera.

15. An audio/video (A/V) recording and communication doorbell system, comprising:
a power diverting means; and
an A/V recording and communication doorbell including a camera, a speaker, a microphone, and a button, wherein the A/V recording and communication doorbell is connected to an external power source;
wherein the A/V recording and communication doorbell is configured to draw power from the power source such that the power flows through a signaling device and the power diverting means in parallel with the signaling device when the power diverting means is in a low impedance state; and
when the button is depressed, the power diverting means is configured to transition to a high impedance state, thereby diverting power from the power source through the signaling device to cause the signaling device to emit a sound.

16. The A/V recording and communication doorbell system of claim 15 , wherein the power diverting means is at least one of external to and internal to the A/V recording and communication doorbell.

17. The A/V recording and communication doorbell system of claim 16 , wherein the power diverting means includes at least one component external to the A/V recording and communication doorbell and at least one component internal to the A/V recording and communication doorbell.

18. The A/V recording and communication doorbell system of claim 15 , wherein the signaling device is external to the A/V recording and communication doorbell.

19. The A/V recording and communication doorbell system of claim 15 , wherein the A/V recording and communication doorbell further includes a timer, wherein when the button is depressed the timer is configured to be activated and the power diverting means is configured to remain in the high impedance state until the timer expires, unless the A/V recording and communication doorbell receives a notification that a call to a client device has been answered.

20. The A/V recording and communication doorbell system of claim 19 , wherein the timer is a first timer and the A/V recording and communication doorbell further includes a second timer, and wherein the power diverting means is further configured to transition to the low impedance state, the second timer being activated when the power diverting means transitions to the low impedance state, and the power diverting means being prevented from again transitioning to the high impedance state unti
