Have you tried Zone Crossing? I just saw a video yesterday on YouTube from HomeTech that used that to reduce the number of false positives. I just tried to post a reply with a link and it didn't show, so will not add the link to this post. Hope that helps

I watched a youtube video yesterday from HomeTech on Zone Crossing. I am wondering if that would reduce your false positives. Not sure if I can post a link but will try.
