Fisheye Dewarping

Fisheye cameras are practical when users want to survey a wide area using a single-lens camera. However, monitoring the camera stream can be disorienting as the camera video will appear warped when initially viewing the camera.

This article will outline how to use the Fisheye Dewarping feature in C3CMS.

 

Supported/Affected Devices

  • DW Standalone Series NVR
  • DW MEGApix Camera Series (fisheye cameras)
