Adjusting the Shutter Limit sets the update time used to maintain the image quality. If you
want to videotape an incident in low-light conditions, you may find that tape quality is not
acceptable. To ensure that the videotape quality is acceptable for possible prosecution
purposes, you may want to test the Shutter Limit settings under the expected lighting
conditions.
