I have some trail cameras that I move throughout my farm. Every time I move it to a place where I think there will be deer. And, every time you can start seeing the pictures of the deer within 12 hours. I honestly don't think they care this time of year.
Heck, this last week a deer walked right by the trail cam within 3 hours of me being there. I don't bother with scent control until I hunt.
You raise an interesting question though. I wonder how much human scent is left on that trail cam. A got a nice 10 point on camera actually smelling the camera. So, perhaps I am wrong for not worrying about scent.
Then again, I don't subscribe to the thinking you need to be 20' in the air either. No more than 10' for me and I fill my tags every year.
