To address those issues, robust techniques that allow object tracking over crowded environments and nonoverlapping cameras [38] will be introduced. New displacement methods to better display the camera views in the video stream area and the switch panel will be analyzed as well. In addition, video analytics systems for wide area surveillance [11] will be investigated to integrate unmanned aerial vehicle videos streams. A dynamic hierarchical view would be investigated to allow operators to select the number of cameras that have to be displayed for a particular area and a particular task.
