The Event Counter

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.

Parameter Description

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.

Individual Events

Specify, whether you want the counted individual events to be saved or deleted. Saved events can continue to initiate actions or messages:

ignore events: Actions are only triggered by the event counter.
use events: Actions are triggered by the event counter and by individual events that have been selected in the Event Selection box.

Counting Period Define the period of time in which the events are to be counted.
Values: 1 .. 3600 seconds

Event Count Enter the number of expected events.
Values: 1 .. 3600

Condition

Define the condition to trigger an event:

More/equal	An event is triggered if the expected number of events has been reached or exceeded.
less	An event is triggered if the expected number of events has not been reached.

Start Action

Define how often the event is to be triggered:

First	The event is triggered only once, i.e. when the condition is first detected.
Every	The event is triggered every time as long as the condition is true.

Storing the Configuration

Click on the Set button to activate your settings and to save them until the camera is rebooted.

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.
