That's a decent bear. Stay with it.
Where is the feed either where he was coming from or going to?
In my experience, he's probably smelling you when you are in checking your cameras, laying low and waiting for you to leave. It also sounds like he's running a "circuit" through his area. He's not a young, stupid bear. The only way to kill him (aside from getting lucky) is to figure out what he's eating, set up watching it from as much distance as you can manage, and wait for the wind to get right and him to make a mistake and come out. Everything has to match up just right though; wind, his circuit, you sitting there... Every year we get big bears on our trail cameras that we never get to see in the flesh. Last year we sat from dark to dark for 8 days before a big boar showed up. This year we sat for 3. We could hear bears in the dark timber ripping apart stumps and huffing that never came out into the open for a shot. They knew we were there and waited for us to leave for the night before showing up on camera...
