Visibility Detection refers to the system’s mechanism to detect if zone visibility is reduced, such as from fog or glare. If a zone is determined to have a loss of visibility, that zone will be placed in recall. Visibility Detection is on for every zone by default, but can be disabled in the Zone Options for a zone that might be exhibiting loss-of-visibility false alarms.
