Four different display modes are available. You can select a display mode as demand.
 180° Panorama: Switch the live view image to the 180° panorama view.
 360° Panorama: Switch the live view image to the 360° panorama view.
 PTZ Expansion: The PTZ Expansion is the close-up view of some defined area in the
fisheye view or panorama expansion, and it supports the electronic PTZ function, which is
also called e-PTZ.
 Fisheye: In the Fisheye mode, the whole wide-angle view of the fisheye camera is
displayed. This view 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.
