Abstract: Tracking an intruder throughout regions in an area under surveillance by locating video cameras to provide an image for each region. For each camera a subset of the cameras are associated as auxiliary cameras to that camera; these associations are stored in a table. One camera is the initial primary camera and displays an initial primary image. An auxiliary video image is displayed for each of the auxiliary cameras that were previously associated with the initial primary camera. An intruder travels from region to region and leaves the primary video image and/or appears in an auxiliary video image. The user selects one of the auxiliary cameras to become a subsequent primary camera, and the video image from the subsequent primary camera is displayed as a subequent primary image. A video image for each of the auxiliary cameras previously associated with the subsequent primary camera will be displayed.
