Battery Spot Light Cameras more false triggers by trees (only during day)?

For the outside of my house I have a wired Spot light, Wire Spotlight, and two Solar Spt light Cameras. The two wired cameras I get very little in false triggers. They are great at even spotting a stray cat in our landscaping. But my two Battery Spot light cameras on the side of our house (no plugs close enough to do wired) get tripped 20-30+ times a day even at the lowest setting for motion. I know the Battery version's use only IR to spot motion but since trees give off little IR I am not sure why motion is getting triggered so much. I am guessing it is the tress because that is the only thing I see moving in the video. Once side of my house faces West and the other faces East, and I noticed the false triggers are wrose when the sun it on that side of the house. I have adjusted the zones and put them to the lowest motion settings and I still get all the notifications. What gets to me is that for my wire spotlight camera there are trees that are closer and larger and it does not trip that camera at all. I just want to get my camera setup to get less faulse trip less. Thanks for any help.
