Doorbell camera
This application is directed to a doorbell camera for illuminating and capturing scenes. The doorbell camera includes at least a subset of processors for operating a camera module, an image sensor having a field of view of a scene and configured to capture video of a portion of the scene, one or more infrared (IR) illuminators for providing illumination, a waterproof button assembly, and a microphone and a speaker for enabling a real-time conversation between a visitor located at the doorbell camera and a user of a remote client device. The waterproof button assembly is configured to receive a user press on a button top, block water from entering the electronic device, and display a visual pattern uniformly at a peripheral region of the button assembly using LEDs and light guide component that are disposed under the button top.
1. A video doorbell device comprising:
a housing that encloses a plurality of electronic components and includes a front cover plate and a body;
a battery disposed within the enclosed region proximate to a rear exterior surface of the housing;
a temperature sensor disposed within the enclosed region, the temperature sensor configured to measure a battery temperature of the battery; and
a main board disposed within the enclosed region, the main board including a central processing unit, the main board configured to:
receive a temperature measurement from the temperature sensor, the temperature measurement indicating the battery temperature; and
in response to a determination that the battery temperature has exceeded a first threshold temperature, disable charging of the battery.
2. The video doorbell device of claim 1 , further comprising a sensor board including the temperature sensor, the temperature sensor being disposed adjacent to the battery.
3. The video doorbell device of claim 1 , further comprising a heater disposed within the enclosed region, wherein:
the heater is configured to generate heat and increase the battery temperature of the battery; and
the main board is further configured to, in response to a determination that the battery temperature is less than a second threshold temperature, enable the heater to generate heat and increase the battery temperature of the battery.
4. The video doorbell device of claim 3 , wherein the main board is further configured to, responsive to a determination that the battery temperature of the battery is equal to or greater than the second threshold temperature, disable the heater from heating the battery.
5. The video doorbell device of claim 4 , wherein the main board includes a charger circuit configured to manage operations of the battery by performing one or more of disabling the charging of the battery, enabling the heater to heat the battery, and disabling the heater from heating the battery.
6. The video doorbell device of claim 1 , further comprising a heat spreader disposed within the enclosed region, the heat spreader configured to dissipate heat generated by one or more of the plurality of electronic components within the enclosed region.
