To view and dewarp video images in Security Desk that were captured using an ImmerVision Panamorph lens, you must configure the lens in Config Tool.
Dewarping allows you to zoom in on a Panomorph image, similar to the digital zoom feature in Security Desk. The zoomed image is dewarped, or flattened to show a rectangular image.
