How high up the tree are you putting it and haw far back from the trail?

I don't get a ton of pics as I don't set up over bait. The trails I set up on are heavily used but on occasion I also get blanked. I'd suggest trying a diffrent location off the same trail. I found when I first set up my cam the deer were walking behind the cam because I set up about 30 feet fram a trail junction. As luck would have it I choose the wrong trail.
