0.0 second duration motion event

Post by llandre » Wed Oct 08, 2014 5:45 pm

As described here http://www.zoneminder.com/forums/viewto ... 30&t=22637 I'm experiencing some problems with zm 1.26.5.
One of the weird things that happen is the recording of 0.0 second duration events. This is one example:

Id Name Monitor Cause Time(v) Duration Frames Alarm Frames Total Score Avg. Score Max. Score
131 New Event garage-modect Motion 10/07 20:37:24 0.00 0 0 0

It seems zm detected a motion event but was unable to process it properly.
However if I restart zoneminder service (sudo service zoneminder restart), the event processing completes nicely: the event is displayed correctly in the events page and the alarm email is sent:
Id Name Monitor Cause Time(v) Duration Frames Alarm Frames Total Score Avg. Score Max. Score
131 Event-131 garage-modect Motion 10/07 20:37:24 82471.27 253159 253133 12742634 50 124

From log page:

I honestly don't know where to look at to further investigate this problem. Anybody can give some hints?

Thank you.

I think I got it. I inadvertently created an undesired circular dependency between two cameras. So they was keeping alarmed each other indefinitely!

Thanks - hadn't realised I did exactly the same thing with a circular dependency.
