Hello,

i have problems to get my zone configured.
When the weather changes zoneminder records.
Thats all correct and fine, but sometimes when its cloudy and sunny i have about 300-400 events at one day.
I can't watch them to check which persons entered the area, because there are too much events.

Here are the pictures of my settings and the alert image.

Thanks in advance if you can help me to get just alarms when a person enters the area.

Take this as a guess, I just want to see how this turns out: That particular event should have been avoided by a max blobs setting, I should think. See how many blobs you can count? Scores if not hundreds. A person's image would have been a far fewer number of blobs. Maybe 20 or less? Try a max blobs setting of about 20-30?

I would really like to see a setting for blob volume per circumference of the largest blob over a specified size. When you have a more person-shaped blob, you would get a much higher volume per circumference ratio of the blobs than all that squiggliness gives.

Yesterday i tried these settings, but i think when i set min blobs to a higher value it could be that no persons or children getting detected:



And got about 500 new events in the night, because of this kind of events:



I have another camera which alerts a lot (/dev/video0, so not an IP Camera), and i found out that in all of the events the time delta was at minus, but never had a alert score:

same problem

In your Monitor::Buffers, set Alarm Frame Count to 3 frames, post results.

Hope it helps,

Thanks for your help.
The buffer setting worked and now the weather changing events are gone, because of setting the Min/Max Pixel Threshold (0-255), Min/Max Alarmed Area and Min/Max Filtered Area to a higher number.

Hi Matti,

Could you please send me your current settings (screenshot, like above is enough)? I have the same problem with my cams, and trying to get it fixed.

Thanks a lot!
