Abstract
In an embodiment, a method includes continuously receiving, from a camera, raw video frames at an initial resolution. The method also includes, for each raw video frame, as the raw video frame is received: downscaling the raw video frame to a first resolution to yield a first scaled video frame; downscaling the raw video frame to a second resolution distinct from the first resolution to yield a second scaled video frame; identifying a location of a target; cropping at least video frame based, at least in part, on the location of the target; and storing the first scaled video frame, the second scaled video frame, and information related to the cropped at least one video frame as part of a first video stream, a second video stream, and a third video stream, respectively.
