Video analytics method and system

摘要

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.

1. A method comprising:
capturing video data using a video source disposed at an acquisition end; storing the captured video data at the acquisition end; transmitting non-adjacent single frames of the captured video data from the acquisition end to a server via an IP network, the non-adjacent single frames of captured video data being transmitted one at a time at known time intervals and absent transmitting a series of consecutive frames of the video data captured between capturing the non-adjacent single frames; at the server, performing video analytics 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; and, in response to detecting an actionable event, transmitting to the acquisition end via the IP network a signal for requesting previously stored video data comprising the series of consecutive frames of the video data captured between capturing the current one of the non-adjacent single frames and the previous one of the non-adjacent single frames.
