The distributed intelligence video surveillance system includes a lead video camera and a plurality of child video cameras that are configured to communicate with the lead video camera. One of the plurality of child video cameras may receive a video image and perform analytics and event generation for any events of interest found within the video image. The child video camera extracts metadata for any found events of interest and communicates the extracted metadata to the lead video camera. The lead video camera communicates the extracted metadata to others of the plurality of child video cameras so that the others of the plurality of child video cameras can be alerted to track the found events of interest.
