Abstract
The various embodiments described herein include methods, devices, and systems for analyzing video streams. In one aspect, a method includes, while receiving a video stream: obtaining motion start information indicating that a portion of the video stream includes a motion event candidate; and segmenting the portion of the video stream into a plurality of segments including an initial segment. The method also includes obtaining a first categorization for the motion event candidate based on the initial segment; and, in accordance with the obtained first categorization, generating a log entry for the motion event candidate including the first categorization. The method further includes: in response to obtaining motion end information, obtaining a second categorization for the motion event based on the plurality of segments; and updating the log entry for the motion event candidate based on the obtained second categorization.
