The main window shows all important information you need. First you must move the camera position to the reference point. The reference point is the leftmost position. After that you must set the null position using the button : 'Set Null'. Now you can drive to any positions and take them into the list by using the 'New' - button. It is the same procedure for updating positions. You can drive to positions directly by using the context menu. In minimized mode the program will stop the live-stream for optimizing the system. The pictures will be saved over the camera directly.
