    • 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.
    • 执行视频分析的方法包括使用设置在采集端的视频源捕获视频数据。 捕获的视频数据被存储在采集端,并且捕获的视频数据的非相邻单个帧经由IP网络从采集端发送到服务器。 所捕获的视频数据的非相邻单帧以已知的时间间隔一次一个地发送,或者以另一个已知的时间间隔发送多个非相邻的单个帧的脉冲串。 在服务器处,对非相邻单个帧中的当前一帧执行视频分析,用于检测相对于前一个非相邻单个帧的可操作事件。 响应于检测到可操作事件,用于请求先前存储的非相邻单个帧中的当前一个帧和前一个非相邻单个帧之间存储的视频数据的信号通过IP网络发送到采集端。
