Abstract: A computing system receives a definition of a zone of interest within the scene depicted in the video steam. In response to receiving the definition of the zone of interest, the computing system determines, for each motion event detected in the video stream, whether a respective event mask of the motion event overlaps with the zone of interest by at least a predetermined overlap factor; and identifying the motion event as an event of interest associated with the zone of interest in accordance with a determination that the respective event mask of the motion event overlaps with the zone of interest by at least the predetermined overlap factor.
