If you can use bait, do it. It will help you overcome alot of other things such as slow trigger speed. It also tends to distract the deer from the camera. I know it's hard, especially with as hot as it's been, but try to be as scent free as possible. Make sure yiur camera isn't looking into a rising or setting sun. That can make the camera do some crazy things. If you are not using a security box, I highly recommend you get one. I try to avoid putting my cams in places that are easily accessable to others, that's just inviting trouble. Have fun and enjoy your new addiction!
