Fisheye Display Modes: below are conceptual drawings for different display modes. 

Zoom In

Zoom Out

An 

Original oval view covers the 

hemisphere taken by the fisheye 

lens.   

A 

Regional view crops a portion of the hemisphere 

as a region of interest. You can zoom in or out or 

move the view area elsewhere from on the regional 

view.    

 (Single Panoramic) Display mode:

With image correction algorithms in firmware, the hemispheric image is transformed into a 

rectilinear stripe in the 1P display mode. Viewers can use the PTZ panel or simply use mouse 

control to quickly move through the 360º panoramic view. 

Note that the 1P view is apt for an overview, the Zoom in/out function does not apply in this 

mode. 

A Regional view is dewarped, by correcting images 

from the distorted oval view to a rectangular and 

visually proportional image.
