• PTZ Expansion ( ): The PTZ Expansion is the close-up view of a defined
area in the fisheye view or panorama expansion. It supports the electronic
PTZ function, also called e-PTZ.
• Radial Expansion ( ): In radial expansion mode, the whole wide-angle
view of the fisheye camera is displayed. This mode is called Fisheye View
because it approximates the vision of a fish’s convex eye. The lens
produces curvilinear images of a large area, while distorting the perspective
and angles of objects in the image.
