Issue Summary

Distortions, known as the Jello effect, appear intermittently in CCTV cameras.

Overview

The Jello effect happens when parts of the frame become blurred or straight lines appear crooked. In video, it is seen as a rising haze or a jelly-like vibration.

This effect occurs in cameras that use a rolling shutter type image sensor. Rolling shutter captures the screen sequentially, line by line, for each frame. Because each line is captured at a slightly different time, the image distorts when the camera moves quickly or when subjects move rapidly across the scene.

Resolution

To alleviate the Jello effect distortion, gradually lower the Shutter Maximum and maintain the value when the distortion is reduced. 

WARNING: Slowing shutter speed can prolong exposure which may cause diffraction 
or saturation due to the aperture. Use caution when adjusting these settings.
