An Original oval view covers the
hemisphere taken by the sheye
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.

1P (Single Panoramic) Display mode:
With image correction algorithms in rmware, 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.
