Abstract
Abstract A surveillance system that includes a number of camera subsystems. Each camera subsystem includes a number of single lens cameras pointing in different directions which simultaneously capture images. Each camera subsystem covers a particular theater of interest. Each single lens camera captures an image of a particular region in a particular theater. When an object of interest is identified, the system can follow the object as it moves between regions and theaters in a facility. When an object is being followed, the system can provide a view of the object as it transitions between regions covered different single lens cameras in a particular camera subsystem and as it transitions between theaters covered by different camera subsystems.
