You need to keep a few things in mind when setting up your cameras. First, you need to be totally familiar with their operation before going afield. Play with them in your living room first, then run them for a while in the backyard. Walk back and forth in front of them at a variety of ranges (night and day) to see what they can do. Practice aiming; targeting a little above your belt buckle is about right for moving deer. Once you get the hang of it, you are ready to head to the field.
