A video management system may send time-stamped metadata corresponding to a video stream across a communication path having a limited bandwidth. Time-stamped metadata for a first reference video frame which identifies objects in the reference frame may be generated, and sent across the communication path. Time-stamped metadata for each of a plurality of first delta video frames following the first reference video frame may be generated, the time-stamped metadata for each of the plurality of first delta video frames may identify changes in detected objects relative to the objects identified in the time-stamped metadata for the first reference video frame. The time-stamped metadata for each of the plurality of first delta video frames may be sent across the communication path.
