Abstract: A surveillance system for detecting and/or characterizing movement of a monitored infrastructure. An improved compromise between tight zone surveillance and number of false alarms is provided by an improved control of a 3D surveillance device. An input functionality is provided for a user to define a 3D subzone within a 3D environment model. A change functionality allows the user to generate a redefined subzone by dragging one of the corner points of the 3D subzone to a different position within a 3D visualization of the 3D environment model, whereby the shape of the 3D subzone is distorted. The input functionality and the change functionality are used to provide to the 3D surveillance device spatial parameters associated with the redefined subzone and the 3D surveillance device is caused to generate an action in case a movement within the redefined subzone is detected by means of the 3D measurement data.
