I have just set up BI at my parents house, and have a question about motion detection/alerts for one particular camera. The camera is a HDW2531 and the scene is as shown in the photo below:

I have already used the zone map feature in BI to block out movement on the road (and have a clone recording 24hrs for that), but I am having a lot of problems when its wind and the tree branches are moving a lot. What are some techniques that others have employed in a situation like this? If I reduce the sensitivity settings in the motion detector then it sometimes misses people walking on the grass. Can tripwire or intrusion be used somehow?
Thanks for your help and looking forward to your replies.
