Fisheye Cameras
De-Warping
Fisheye cameras use very wide angle lenses to capture hemispherical images - 180° panoramic
view (wall mount) or 360° surround view (ceiling/floor/wall mount) without blind spots.
victor allows hemispherical images captured from fisheye cameras to be converted into
conventional rectilinear or panoramic projections for viewing and analysis. This process is known
as De-Warping.
The option to De-warp is available via the context menu of supported fisheye camera views. This
can be done in Playback and Live modes as well as from within victor Player. It is also available in
Video Search Results player and Investigator windows.
It is also worth noting that sending an image to another display or InstantView etc. will open the
Fisheye camera in whichever view is set by default in Setup -System Values- Video Preferences.
Note
Exported video can be de-warped within victor player but if exported footage is played back in
alternative players, there is no option to de-warp the video.
De-Warping preferences are available in System Values. Here you can configure the default de-
warp mode from the following:
VideoEdge NVR 4.4+ also offers the option of selecting a default camera mounting for fisheye
cameras.
