Since you didn't tell us where you are located, or any description of hunting that goes on around your area, it's hard to be specific. Besides, we are talking about deer so specifics don't apply, anyhow. I'd imagine that there may be some hunting pressure being applied on properties surrounding yours. Also, it's not unusual for the deer to simply vanish during the rut. There could be better food sources, such as a heavy acorn crop in the swamp that pulls them away from your bait, or there could be some agriculture or food plots on surrounding properties. It's not unusual to see strange bucks during the rut, when they are out cruising for hot does, and during the pre-rut the younger bucks are being pushed out of the area by the bigger more dominant bucks. Those big dominant bucks will lock down on does that about to come into heat, and often manage to keep those does corralled in the bedding areas. You might actually need to search out travel routes and go into the swamp (if you have permission to hunt it) in order to find out exactly where the deer are holding up. Another thing to remember is that often deer will change their patterns when the weather changes. What they do in the spring and summer may not be what they do in the fall and winter. I'd move that trail camera to some other locations and leave it for a week or two and see what shows up in the pictures, and then decide where to relocate my stand, if I were in your position.
