I would try it in house on the pet, if you have one, or your self. If that works fine. Try it in your yard pointing east for the morning, south for the afternoon, and west for the evening. Make sure it is a sunny day, to see if the sun is activating it. I have had this problem in the past, very frustrating. Now, I try my hardest to have the cameras set up, facing north. Some people don't have problems with multiple triggerings like that, but I did, and it was from the sun. I can't think of one time that I have had that problem with a north facing camera. But I can think of multiple times while facing south or east.
Also, maybe try slightly elevating your camera and point slightly downward, if you have to face it south or east.
It is expecially frustrating if you have to drive any distance (mine is 70 miles) for a memory card full of branches or grass
. Everytime I put a camera in a new spot, I get nervous that that is going to happen
.
hope this helps you out.
Oh yea, and I would trim those branches too.
