Interactive sample display
The main section of the program shows a live video feed from either of the system cameras. The view can be changed at any time by pressing the camera exchange symbol located in the status bar.
Software elements such as the crosshair or a structure preview are shown on the video feed depending on the context. The underlying sample can be moved by dragging on the screen with the mouse cursor.

Recorded media, such as screenshots, are stored in a database on the system computer. Already acquire media can be inspected by expanding the media bar. The data can later be accessed and/or exported into standard formats, e.g. for presentation purposes or further processing.
On this popup the following buttons are present:
