I agree with pastor Jim. When you go to hunt the area either pull the camera or swap memory cards or use your card reader whatever method you use to check your camera's. I just hung a camera today on a mock scrape (with a dripper) I made with the intention of hopefully hunting it next weekend. The nice thing is that I have to cross a river to get to it so it forces me to stay out of the area until I know I've given it enough time to start working.
