How to save a video sequence when an alarm occurred?

[eivanovic]

When using the WinCC OA Video Add-On you can save a video sequence if an alert occured.
At the recording function you can define the time range before and after the alarm time which shall be recorded in the video sequence.
The recording function is started/stopped by setting a specific command on the datapoint used for the video camera.

For details please have a look at the WinCC OA documentation: Add-ons --> Video --> Object Explorer --> System components --> Recording.
