1. A system for reconstructing video from one or more cameras to track an object across a plurality of cameras, the system comprising:
a display;
a memory storing computer executable instructions; and
at least one processor programmed to:
access stored video from a plurality of cameras;
cause to display a first transition zone overlay over an area of a first camera image on a screen rendered from the stored video, in order to track movement of an object from a first field of view of the first camera to a second field of view of a second camera, wherein the first transition zone overlay is selectable by a user to navigate from the first field of view of the first camera to the second field of view of the second camera to track the object across a plurality of cameras; and
responsive to selection of the first transition zone overlay by the user, cause to display a second image of the second field of view of the second camera from the stored video and a second transition zone overlay over an area of the second image as the object moves between the first field of view and the second field of view.
