In the past I've always said it doesn't........and I still after this year say it does not scare the deer. I had one of my cameras about 60 yard from one of my stands. Twice this years I was in my stand and saw the camera flash several times and the deer never left......their heads came up.....and one investigated the camera(sniffed it) I still don't think it scares them. On the other hand I will gaurranty it will "SCARE THE CRAP OUT A HUNTER."

Been there...GoodLuck!
