In the multiview profile for “Events”, why is the colored frame of the visual alarm (VA) visible on some alarm images but not on others?
ANS:
The Visual Alarm for an event (e.g. a red frame around the image) is activated for a specific, pre-defined period of time after the event. That’s why it might appear in the post-alarm images, but not necessarily in the actual event image itself.
In the case that the event dead time (the earliest pre-defined time after which the camera will evaluate another event) is shorter than the time set for the display of the visual alarm and a new event takes place within this period, the visual alarm from the previous event will still be visible for the following event image. In this case, the new event image will also be marked with the visual alarm (from the last event).
