Put the trail cam on the tree with the white thing on it. And put a branch on the top to angle it down. Better close up for the shots. Also put a 5 gallon bucket there so you can use it for size comparison on a bear there.
the white thing is an old t shirt I wore for a day trying to get the bear used to my sent. The tree with the cam on it is the same distance away from bait and about 4' up the stump is about 5' high and cam is pointing north swamp is on west (left) and a thicket on east (right) I thought about moving cam to a steel post and move it closer, a little nervous about losing cam. Also the cam is about 18' from bait
When it comes to scent, there are basically two types; those that attract and those that mask. I've tried both on many occasions. There are lots and lots of "doe in heat" scents, designed to attract a big buck into range. I've also used a "cow in heat" scent while elk hunting.
Another scent would almost be better named as a "coverup smell". The main goal is to cover up human odor or mask it. Though I don't believe you can ever totally eliminate all human...
