Game camera mounting

How is everyone mounting their cameras? I've got one of mine on a small mesquite about the size of a man's thigh with the top cut out and I'm getting way to many pictures of nothing. I have the camera sensitivity turned to low and it doesn't seem like the Bush moves around much by hand but apparently it does. I'm assuming I need to move it to a t-post to limit the pics of nothing but landscape? Anyone have any other tricks. This is my first year using a trail cam so don't kill me to bad.

Your camera could be getting trigger by tall weeds blowing in the wind or a bird flying by. If the trail camera's trigger speed is not fast enough you will never see the birds.

I weld 1/4" steel to a T post and bolt a steel security case to it. Can be put anywhere!

Mounted plywood to T-post with U bolts. Mounted plywood to tree with screws and shims. Always used weed eater on all grasses in front of camera, trim brush back at least 30-40 feet out front. Don't mount it too high like to keep mine about waist high.
