Shadows causing a lot of motion alerts

[brokenarrow03]

Hello

The last week it has been pretty windy here and that is causing the trees to rustle quite a bit. I have done a pretty descent job of excluding the trees from the motion zones but when it is windy the tree shadows that cross my zones cause motion alerts. I have done some adjusting to "min object size" and "min contrast" with little success. Does anyone have the same issue and found a good combo of these settings that will still detect cars, ppl, dogs, etc?


Thanks

I've found "zone crossing" is the best way for me to reduce shadow triggers.

Strategically define the zones then set a trigger for bi-directional crossing.
