Abstract

Various smart doorbell arrangements are presented. Based on a measured temperature of the smart doorbell, operation of the smart doorbell device may be altered such that more heat or less heat is generated without affecting user-facing features. Based on another measured temperature, operation of the smart doorbell may be altered such that a chime that is electrically coupled to the smart doorbell device is not sounded in response to a doorbell actuation, but that a notification of the doorbell actuation is wirelessly transmitted by the smart doorbell device.

First claim

What is claimed is:

1. A method for operating a battery-powered device mounted at a structure, the method comprising:
monitoring by the device an aspect of the structure;
enabling user interaction with the device, including providing one or more users with information related to the aspect;
measuring an operating temperature of the device;
determining that the operating temperature has crossed a temperature threshold; and
altering operation of the device in response to determining that the operating temperature has crossed the temperature threshold, including altering one or more functions of the device having secondary effects that change the operating temperature of the device.

2. The method of claim 1 , wherein the one or more functions are associated with non-user facing features of the device.

3. The method of claim 1 , wherein the one or more functions of the device include a first function of the device to increase the operating temperature of the device when the operating temperature is below the temperature threshold.

4. The method of claim 1 , wherein the one or more functions of the device include a second function of the device to decrease the operating temperature of the device when the operating temperature is above the temperature threshold.

5. The method of claim 1 , wherein:
the device is a connected camera that includes an image sensor for capturing video, a microphone for capturing audio, a transceiver for transmitting the video and/or the audio to the one or more users of the device, and an illuminator for illuminating a field of view of the camera, and
altering the one or more functions includes altering respective functions of the transceiver and/or the illuminator.

6. The method of claim 5 , wherein altering the respective functions of the transceiver and/or the illuminator includes:
increasing transmission power of the transceiver and/or illumination power of the illuminator; and
decreasing transmission power of the transceiver and/or illumination power of the illuminator.

7. The method of claim 5 , further comprising: managing the altering of the one or more functions to avoid deterioration of quality of the audio and/or the video during the altering.

8. The method of claim 5 , further comprising: transmitting via the transceiver, a video stream.

9. The method of claim 8 , further comprising: transmitting via the transceiver, a wireless notification message that is linked to a video clip of the video stream transmitted by the device.

10. The method of claim 1 , wherein the device further includes a fan, and altering the operation of the device includes activating the fan.

11. The method of claim 1 , wherein the device is coupled to a battery and the operating temperature of the device is based on an operating temperature of the battery of the device.

12. The method of claim 11 , further comprising:
measuring a voltage of the battery; and
determining the temperature threshold based on the measured voltage of the battery.

13. The method of claim 12 , wherein the temperature threshold is selected from at least a first temperature threshold and a second temperature threshold, the first temperature threshold corresponding to a higher voltage and lower temperature than the second temperature threshold.

14. A battery-powered device mounted at a structure comprising:
a housing;
one or more temperature sensors located within the housing;
a wireless interface located within the housing;
one or more processors located within the housing; and
memory coupled to the one or more processors, the memory storing one or more programs including one or more instructions that when executed by the one or more processors cause the device to:
monitor by the device an aspect of the structure;
enable user interaction with the device, including providing one or more users with information related to the aspect;
measure an operating temperature of the device;
determine that the operating temperature has crossed a temperature threshold; and
alter operation of the device in response to determining that the operating temperature has crossed the temperature threshold, including altering one or more functions of the device having secondary effects that change the operating temperature of the device.

15. The device of claim 14 , wherein the one or more functions are associated with non-user facing features of the device.

16. The device of claim 14 , wherein the one or more functions of the device include a first function of the device to increase the operating temperature of the device when the operating temperature is below the temperature threshold.

17. The device of claim 14 , wherein the one or more functions of the device include a second function of the device to decrease the operating temperature of the device when the operating temperature is above the temperature threshold.

18. The device of claim 14 , further comprising:
a connected camera that includes an image sensor for capturing video;
a microphone for capturing audio;
a transceiver for transmitting the video and/or the audio to the one or more users of the device; and
an illuminator for illuminating a field of view of the camera, and
wherein altering the one or more functions includes altering respective functions of the transceiver and/or the illuminator.

19. The device of claim 18 , wherein device includes an actuation interface; and
the video is not interrupted in response to the device being actuated.

20. The device of claim 14 , wherein the device is electrically connected to a chime via a bypass unit.
