8. The method for operating the smart doorbell device of claim 1 , wherein the doorbell chime is electrically connected with the smart doorbell device via a bypass unit.

9. The method for operating the smart doorbell device of claim 1 , further comprising:

in response to determining that the measured temperature has crossed the temperature threshold, increasing, by the smart doorbell device, a wireless transmit power level of a wireless transmitter of the smart doorbell device to increase heat generation within the smart doorbell device.

10. The method for operating the smart doorbell device of claim 1 , further comprising:

in response to determining that the measured temperature has crossed the temperature threshold, activating, by the smart doorbell device, one or more infrared illuminators to increase heat generation within the smart doorbell device.

11. The method for operating the smart doorbell device of claim 1 , further comprising:

detecting, by the smart doorbell device, a second actuation of the doorbell;

in response to detecting the second actuation of the doorbell, transmitting, by the smart doorbell device, a second wireless notification message that indicates the second actuation of the doorbell; and

in response to detecting the second actuation of the doorbell, activating the doorbell chime.

12. A smart doorbell device comprising:

a housing;

a doorbell interface, attached with the housing, that is configured to be actuated by a user;

a battery module located within the housing;

one or more temperature sensors located within the housing;

a wireless interface located within the housing;

chime activation circuitry located within the housing; and

one or more processors located within the housing that receives data from the one or more temperature sensors and the doorbell interface, communicates with the wireless interface, and controls the chime activation circuitry, wherein the one or more processors are configured to:

receive a measured temperature from the one or more temperature sensors;

determine that the measured temperature has crossed a temperature threshold;

alter operation of the smart doorbell device in response to determining that the measured temperature has crossed the temperature threshold;

detect actuation of the doorbell interface after altering the operation of the smart doorbell device; and

transmit a wireless notification message via the wireless interface that indicates actuation of the doorbell interface after altering the operation of the smart doorbell device and in response to detecting the actuation of the doorbell interface, wherein the chime activation circuitry is not triggered to sound a doorbell chime in response to the actuation of the doorbell interface.

13. The smart doorbell device of claim 12 , wherein the one or more processors are further configured to:

receive an indication of a voltage of the battery module; and

determine the temperature threshold based on the voltage of the battery module.

14. The smart doorbell device of claim 13 , wherein the one or more processors are further configured to:

select the temperature threshold from at least a first temperature threshold and a second temperature threshold, wherein the first temperature threshold corresponds to a higher voltage and lower temperature than the second temperature threshold.

15. The smart doorbell device of claim 12 , further comprising a camera, wherein the one or more processors are further configured to:

transmit, via the wireless interface, a video stream captured using the camera.

16. The smart doorbell device of claim 15 , wherein the wireless notification message is linked to a video clip of the video stream transmitted via the wireless interface.

17. The smart doorbell device of claim 12 , wherein the doorbell chime is electrically connected with the chime activation circuitry via a bypass unit.

18. The smart doorbell device of claim 12 , wherein the one or more processors are further configured to:

increase a wireless transmit power level of the wireless interface to increase heat generation within the smart doorbell device in response to determining that the measured temperature has crossed the temperature threshold.
