The Event Filter dialog contains all filters available for influencing the occurrence of events.
The Event Dead Time prevents 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.
Individual Events controls if only the event counter is allowed to trigger actions or if individual events may also trigger actions.
|Events to Count||In the Event Selection list select the events to be counted. Hold the [Ctrl] key pressed to select more than one event.|
Specify, whether you want the counted individual events to be saved or deleted. Saved events can continue to initiate actions or messages:
|Counting Period||Define the period of time in which the events are to be counted.
|Event Count||Enter the number of expected events.
Define the condition to trigger an event:
Define how often the event is to be triggered:

Click on the Restore button to undo your most recent changes that have not been stored in the camera permanently.
Click on the Close button to close the dialog. While closing the dialog, the system checks the entire configuration for changes. If changes are detected, you will be asked if you would like to store the entire configuration permanently.
