A method for performing video analytics comprises capturing video data using a video source disposed at an acquisition end. The captured video data is stored at the acquisition end, and non-adjacent single frames of the captured video data are transmitted from the acquisition end to a server via an IP network. The non-adjacent single frames of captured video data are transmitted one at a time at known time intervals, or a burst of a plurality of non-adjacent single frames is transmitted at another known time interval. At the server, video analytics is performed on a current one of the non-adjacent single frames for detecting an actionable event relative to a previous one of the non-adjacent single frames. In response to detecting an actionable event, a signal for requesting previously stored video data captured between the current one of the non-adjacent single frames and the previous one of the non-adjacent single frames is transmitted to the acquisition end via the IP network. |
