ZoneMinder EventState takes too long. Check "Received forceAlarm" instead

I’ve installed Zoneminder on my Debian-System and got the Zoneminder Binding working in openHAB 2.3.

The problem that i have is that the EventState takes too long to change from OFF to ON.

My Camera is above my front door. So if I close the door (time 16:13:34.861) the system recognizes a motion about 6 seconds later Received forceAlarm (16:13:40.713). This would be fine, but the state of the EventState changes 18 seconds after I’ve closed the door (16:13:52.607). This works too slow for my project, because I created a rule that checks if a motion gets detected in case the lock on the door changes from OPEN to CLOSED.
I don’t want to wait for 18 seconds after I closed the door to lock my house. 6 Seconds would be totally fine.

So is there a way that the system sets the EventState faster? Or can I check the Received forceAlarm from Zoneminder? The motion gets detected fast enough from Zoneminder and technically also from openHAB.
