The Event Filter dialog contains all filters available for influencing the occurrence of events.
The Event Dead Time will prevent new events from triggering after an event has been detected.
The Event Counter (EC) prevents events from being triggered immediately. It only triggers an event if a certain number of events within a defined period of time has been exceeded/reached or not reached, respectively.
Each image will increase the event counter by one, even if multiple event sensors are active at the time.
The event counter can be used, for example, for monitoring a conveyor belt in a production scenario. If fewer events occur than expected during the defined period of time, a malfunction is recognized and the camera triggers an alarm.
Also, the event counter is necessary to avoid false alarms of the video motion (VM). Due to the event counter, an event is only triggered when events occur e.g. for as long as two to five seconds. This way, you can make sure that the object is really moving.
|Event Counter Enable||
If the event counter is enabled, this event will trigger alarms. The event counter counts all events selected in the Event Selection box.
