Task:
You want the camera to alarm a security service or forward the alarm to a central office via motion detection (Video Motion, VM). In any case, you want to keep the number of alarms low with reliable results!
How it works:
The area you want to monitor is equipped with many small VM windows that are very close together (checkerboard pattern). The number of times the individual VM windows are triggered is monitored and filtered by the Event counter (Setup Menu > Event counter). An event is not triggered until at least three VM windows of e.g. two seconds are activated.
Camera settings:
Step 1:
Make sure that VM event is activated and that the windows are defined. To do so, activate Video motion detection (VM=Video Motion) in the Setup Menu > Event settings. The parameters can now be entered in the corresponding text box for the individual windows.
Note: Comments can be inserted by first adding a hash character “#”.
Here is an example that contains windows for the right as well as the left image sensor (in this case, the night sensor of a night model):

To save the settings, first click Set and then Close.
Step 2:
Access the Setup Menu > Event counter dialog and then activate the event counter. In the Events to count field, mark the option for VM – Video Motion Detector. Adjust the values for the Counter window and the Number of events to meet your needs.
Values that match the example above are:
* Counter window: 2 (value in seconds)
* Number of events: 4 (number of events triggered by e.g. VM)
Note:
Retain the standard values for the following fields:
* Individual events:Ignore events
* Condition:More/Equal
* Start action: Every time
To save the settings, first click Set and then Close.
A series of images should be saved for an event in any case. Open the following dialog: Setup Menu > General event settings, and enter the following values:
* Event dead time: 2 (value in seconds)
* Image series:
o Pre-alarm: 6
o Post-alarm: 6
* Recording break:
To save the settings, first click Set and then Close.
Note: To tweak the parameters for the event counter, it is advisable to activate the level display for the event counter in ( Setup Menu > Display and text settings):
* Click on More to see all the options in the dialog. Now you will see other possible settings, including Level display.
* Select the option for Diagram.
* Mark the option Event counterin the field for Data for level display.
Save the new settings by clicking Set and then Close. In the lower left-hand corner of the live screen, you should now see a diagram.
The diagram indicates the internal count (in this case, the number of VM events) of the event counter. Each new value is shown as a step. Once the threshold value has been reached (the value in the event counter window), this will be indicated in another color (red).
Note: Now you need someone to run through the detection area of the camera while you observe the diagram of the event counter. This is how you can determine the optimum values for the Counter window and the number of events.
