Fisheye Playback

Fisheye playback function allows you to play the fisheye camera's video in fisheye dewarping mode. Fisheye dewarping mode refers to the process of perspective correction of an image, to reverse the effects of geometric distortions caused by the fisheye camera lens. Dewarping allows you to cover a wide area with a single device and have a normal view of an otherwise distorted or reversed image.

3. Select a fisheye camera from the camera list to start playback.
   Note:

   For detailed configuration about playback and playback control, refer to Normal Playback.

4. Move the cursor to the display window, and click on the appearing toolbar to enter the fisheye dewarping mode.
5. Drag on the video to adjust the view angle.
6. Scroll the mouse wheel to zoom in or zoom out the view.
