I would bet on the facts that these guys are right. I think it is a combination of the two, You came in excited to see what you had on the camera and did not think about your scent, or they had moved for a while to check out a new food source. Like they said have patience they will be back. Also this is all part of finding the pattern of the deer on your property as well check out your surroundings and look for sign and move your cameras, and see what you come up with. Good luck.
