Dear list,

first of congratulations to this great software. I bought a FCS-3000 and the supplied windoze software was just crap.

After some efforts, I made Zone Minder working on a SuSE box.
One problem remains, I have defined a single active zone for motion detection. It is a polygon with 5 points. It works fine, but I have zmfilter.pl crashes quite often (every 10 minutes in average, depending on configuration):

The settings I use which cause the crash
Min Pixel Threshold 10
Width 9, height 9
zone area 341543
min alarmed area 600
min filtered area 500
max filtered area 50000
min blob area 20
min blobs 2

The web interface fills in 0 for the unused max values, must I supply a value there?

Any clue?

PS: For my motion detection application, the camera is placed outside in the garden with some electrical lights connected to a motion detector. The camera itself has a IR light integrated. When the electrical light switches on / off a event is triggered on the camera. Any hint to suppress this? I want to trigger the camera on a motion event not on a change in environment light condition.

Having zero for the maximum values is not a problem I don't think. Is there anything in zmfilter.log that gives any more of a clue as to why it crashes? Also I would check your db with mysqlcheck just to eliminate that as being a cause.

I had to change the resolution of the camera, thus I had to readjust the filter parameters.
I also had to increase the shared memory as I added a second camera.
I'm not sure, but maybe it is not a good idea to adjust the share memory size at runtime.

Now it looks pretty stable. No "died" or "crashed" in the log anymore.
