Abstract: A system for tracking movable objects in a scene comprising a first overview unit arranged to capture a first overview of a first portion of a scene, and a second overview unit arranged to capture a second overview of a second portion of a scene, wherein the first portion and the second portion may be partly overlapping. The system further comprises a PTZ-camera to image selected objects in the first or second portion of the scene. The first and the second overview unit are configured to detect and locate moving objects in the scene, and to transmit positional data of said moving objects to a control unit that determines if two or more movable objects may be imaged using a single view of the PTZ-camera, and to send instructions to the PTZ-camera to image said two or more movable objects concurrently.
