Configure the dewarp settings for third-party panoramic cameras

Last modified: Thursday October 27, 2022.

When viewing the dewarped view from your third-party panoramic cameras, you might notice that objects (such as people or vehicles) appear distorted, looking either stretched or compressed.

These settings do not apply to Avigilon Ava 360 devices, as the Avigilon Ava cameras dewarp feature is optimized for these camera lenses.

Avigilon Alta provide the following dewarp options, for different lens types in your panoramic cameras:

  • Equidistant dewarp
  • Stereographic dewarp

Setting the correct dewarp option for your specific panoramic camera is often a matter of personal preference — experiment with the settings to discover the option that you think looks best for each of your third-party panoramic cameras.

Prerequisites

To use the dewarp options, the camera must be:

  • a third-party panoramic device (not a Avigilon Ava 360,
  • set up as a panoramic device (see Work with panoramic cameras
  • configured as a ceiling-mounted device (currently, dewarp for wall-mounted pano cameras is not supported)
