Abstract: The various implementations described herein include methods, devices, and systems for illuminating and capturing scenes. In one aspect, a video camera assembly includes: (1) one or more processors configured to operate the video camera assembly in a day mode and in a night mode; (2) an image sensor having a field of view of a scene and configured to capture video of a first portion of the scene while in the day mode of operation and in the night mode of operation, the first portion corresponding to the field of view of the image sensor; (3) one or more infrared (IR) illuminators configured to provide illumination during the night mode of operation while the image sensor captures video; and (4) an IR reflector component configured to: (i) substantially restrict the illumination onto the first portion of the scene, and (ii) illuminate the first portion in a substantially uniform manner across the field of view of the image sensor.

Abstract: A method of detecting and responding to a visitor to a smart home environment via an electronic greeting system of the smart home environment, including determining that a visitor is approaching an entryway of the smart home environment; initiating a facial recognition operation while the visitor is approaching the entryway; initiating an observation window in response to the determination that a visitor is approaching the entryway; obtaining context information from one or more sensors of the smart home environment during the observation window; and at the end of the time window, initiating a response to the detected approach of the visitor based on the context information and/or an outcome of the facial recognition operation.
