shadows

Hi, I have three cameras set-up to monitor my cabin in a wooded area. On a sunny day when the wind is blowing the shadow from the trees will set-off the motion detectors. Is there a setting in the software or someway I can have the motion detection ignore the shadows? Thanks, Rich

I thought I had read on here somewhere (too many posts, so little time!) that you can play back clips and run them through "something" (sorry do not remember what) to be able to try to fine tune your trigger settings. I has been very windy and lots of trees and sun causing all kinds of shadows...
