help to circumvent shadow triggering

[marklyn]

I've tried a variety of settings in BI to try and circumvent triggers from occurring when the tree shadows start moving due to wind.
I would appreciate any tips that anyone can offer in fine tuning my settings to not record tree shadows vs someone (or something) moving about 10' in the video field as shown below. Would appreciate knowing if your tips are based on a similar situation and if it works well for you.

Have you seen the Motion Detection tutorial video on this page?

Playing around with the "object moves a minimum number of pixels" setting filtered out a lot of tree branches during his video.

Thanks, I'll look at it. I've see a variety of things in all of the forums but nothing so far has really helped me.

I think a combination of "object moves a minimum number of pixels" and making three different zones and using zone crossing could probably reduce it a lot! He demonstrates both in the video.

Great, I will watch now. I've never been able to get the "object moves a minimum number of pixels" correct to distinguish the difference between a bug flying across the fov vs a dog/man traipsing across the fov...
