One thing I've found about trail cams is that you might capture a picture of a good deer ONCE even with the camera there for weeks. That is hardly a movement trend nor does it make figuring out where he is during shooting hours much easier. Not being a smart a**, but I've just NEVER been able to get pics of the same deer on the same trail day afte day after day. At least not in the type of habitat I hunt.
Back to your question, the answer may be FORCED MOVEMENT. In other words, a deer push of some sort. Obviously these can be overdone and blow deer right out of the country, but when done carefully and occasionally, these can be very good ways to get the big boys to move. Just figuring out where they'll move is the difficult part. But I've noticed that when I bump deer walking out of the woods that they'll often do the same thing, run the same general way, etc. Then if I have someone else replicate that movement (with me getting to the escape area first), you can have some exciting action and often see deer that you don't see normally. Might be worth a try. We've got a property where the deer often use an escape that is almost circular and when done right, I've had some very close calls with some really nice bucks. I just do most of my hunting by myself so don't the opportunity to try it as much as I'd like.
