• 360° Panorama ( ): Switch Live View image to the 360° panorama view.
• PTZ Expansion ( ): The PTZ Expansion is the close-up view of a defined
area in the fisheye view or panorama expansion, and it supports the
electronic PTZ function, which is also called e-PTZ.
• Radial Expansion ( ): In the radial expansion mode, the whole
wide-angle view of the fisheye camera is displayed. This view mode is

eye. The lens produces curvilinear images of a large area, while distorting
the perspective and angles of objects in the image.
