Described herein are systems and methods for presenting video data to a user. In overview, video data originates from a source, such as a capture device in the form of a camera. This video data is defined by a plurality of sequential frames, having a common geometric size. This size is referred to as the “geometric bounds of captured video data”. Analytics software is used to track objects in the captured video data, and provide position data indicative of the location of a tracked object relative to the geometric bounds of captured video data. Video data is presented to a user via a “view port”. By default, this view port is configured to display video data corresponding to geometric bounds of captured video data. That is, the view port displays the full scope of video data, as captured. Embodiments of the present invention use the position data to selectively adjust the view port to display a geometrically reduced portion of the geometric bounds of captured video data, thereby to assist the user in following a tracked object. |
