To view and dewarp video images in Security Desk that were captured using a Sentry 360 degree fish-eye camera lens, you must configure the lens in Config Tool.

What you should know

Dewarping allows you to zoom in on a 360 degree image, similar to the digital zoom feature in Security Desk. The zoomed image is dewarped, or flattened to show a rectangular image.


  1. From the Video task in Config Tool, select the camera to configure.
  2. Click the Hardware tab.
  3. From the Lens type drop-down list, select Sentry 360.
  4. Click Edit ().
  5. In the Calibrate lens dialog box, do the following:
    1. Use the Width and Height fields to set the Dewarped resolution values.
    2. To set the center position of the fish-eye, drag the left mouse button.
    3. To adjust the radius of the fish-eye, drag the right mouse button.
      NOTE: The blue region represents the area that can be dewarped in a Security Desk tile.
  6. Click OK > Apply.

After you finish

For your changes to take effect, remove the camera from all Security Desk tiles, and then re-add the camera.
