1. A storage system comprising:
a memory; and
a controller configured to:
track an object in a plurality of video streams by determining a correlation value of the object in each video stream of the plurality of video streams; and
in response to the correlation value exceeding a threshold:
determine which video frames in each video stream of the plurality of video streams contain the object;
create a separate video stream using the video frames that contain the object; and
store the created separate video stream in the memory.
