5. The method as described in claim 1 , wherein determining whether the one or more persons, animals, or objects are approaching the smart home environment is based on a signal transmitted from a first electronic device associated with the smart home system and received at a hub device, the signal indicative of the one or more persons, animals, or objects approaching the smart home environment.
6. The method as described in claim 5 , wherein a camera external to and separate from the hub device transmits the signal to the hub device indicative of the one or more persons, animals, or objects approaching the smart home environment.
7. The method as described in claim 1 , further comprising, capturing, prior to determining whether the one or more persons, animals, or objects are approaching the smart home environment, a plurality of images of the one or more persons, animals, or objects, the plurality of images including at least portions of a face of a respective person or animal of the one or more persons, animals, or objects.
8. The method as described in claim 7 , further comprising determining, based on the at least portions of the face of the respective person or animal in the plurality of images, an increase in dimension in the face of the respective person or animal between successive images, and wherein determining whether the one or more persons, animals, or objects are approaching the smart home environment is based at least in part on determining the increase in dimension in the face of the respective person or animal between successive images.
9. The method as described in claim 1 , wherein determining that one or more persons, animals, or objects are approaching a smart home environment is based on at least one of:
determining that the one or more persons, animals, or objects approaching the smart home environment are within a threshold distance; or
determining that one or more persons, animals, or objects approaching the smart home environment entered an activity zone.
10. The method as described in claim 9 , wherein the threshold distance is determined based at least in part on quality information associated with sensed data or a prior configuration established by the user of the smart home system.
11. The method as described in claim 1 , wherein the identification information usable to characterize the identity of the one or more persons, animals, or objects includes data relating to one or more of a voice signature, facial features, a height, a shape, a movement, or behavioral characteristics of a respective person, animal, or object of the one or more persons, animals, or objects.
12. The method as described in claim 1 , wherein the smart home system comprises an electronic greeting system.
13. The method as described in claim 1 , further comprising:
determining that the sensor data is insufficient to perform at least one of facial recognition or object recognition; and
outputting a notification indicative of a request for the one or more persons, animals, or objects to provide information usable to perform at least one of facial recognition or object recognition.
14. The method as described in claim 13 , wherein the notification requests a respective person of the one or more persons, animals, or objects to present their face to the one or more sensors associated with the smart home system.
15. The method as described in claim 1 , wherein initiating the observation window is in response to determining that a plurality of persons of the one or more persons, animals, or objects are determined to be approaching the smart home environment.
16. The method as described in claim 15 , wherein obtaining identification information in response to initiating the observation window, comprises obtaining identification information for each of the plurality of persons.
17. The method as described in claim 16 , further comprising, cropping, responsive to obtaining identification information for each of the plurality of persons, images to include at least portions of a face for each of the plurality of persons.
18. The method as described in claim 1 , wherein a predetermined time threshold ending the observation window is based at least in part on a distance of the one or more persons, animals, or objects approaching the smart home environment.
19. A smart home system comprising one or more processors and memory coupled to the one or more processors, the memory storing one or more programs configured to be executed by the one or more processors, the one or more programs including instructions for:
determining whether one or more persons, animals, or objects are approaching a smart home environment;
