The Previous conditional rule is used to generate complex scenarios and will be triggered when a certain rule occurred previously within a certain period of time. This rule is useful when combined with some other conditional rule such as the Logical Filter And, where for example, it could be triggered if a Presence rule was triggered but before the Presence rule, a Loitering rule was triggered 1 second before . When selecting this condition the following options are available:
•Name: Condition name;
•Can trigger events: Check this condition with the possibility of triggering events;
•Input: Rule where you want to apply this filter;
•Interval (milliseconds): Interval from the previous rule trigger.
•Per Target: If this option is checked, the system will trigger an independent event for each object.
•Event Actions: Desired alarm actions when analytics trigger events. To learn more about alarm actions see chapter How to configure alarm actions.
