Ganz GXi Series VCA Interface Manual V3.05.31.18 Learning Clause When scene change detection is enabled, if tracking system detects a drastic change in the scene it temporarily disables the tracking while it learns a new scene model. The 'learning' clause is triggered for the duration of this learning period, so allows the scene learning to be used as an input to a logical rule. Action Types Actions can be assigned to logical rules to perform tasks when they are triggered. Actions are not required in all situations, for example if a logical rule is only to be used as an input to another logical rule using the 'rule' clause. Generate Events Action Adding the 'GenerateEvents' action to a logical rule will make it generate events on the meta-data output in the same way that standard rules generate events. Without the 'GenerateEvents' action, a logical rule will not send events to any other system components. The output of a logical rule can be always be used by a 'rule' clause and this behavior is not affected by the presence of the 'GenerateEvents' action. Reset Counter Action The 'ResetCounter' action will reset a chosen counter to zero whenever the associated logical rule is triggered. The counter will remain at 0 for the duration of the time when the logical rule is triggered, and it will only be possible to increment or decrement it when the logical rule is no longer triggered. Trigger Scene Learning Action The 'LearnScene' action will cause the tracking system to re-learn the scene information. The 'LearnScene' action can be used in situations where there is a detectable change to the scene that is known to reduce the tracking performance such as lights being switched on or off. The scene will be learned again once the associated logical rule is no longer triggered. Increment Counter Action The 'IncrementCounter' action will increment the chosen counter by the specified value whenever the associated logical rule is triggered. The action can also be used to decrement counters by setting the increment value to a negative number. 05-2018-A 64 | P a g e
