I've got a few suggestions. I worked for an outfitter in Canada for four years and these are some things I learned while being involved in the harvest of about 140 bears up there as well as running hounds on bear here in Utah since I was old enough to follow my dad around the woods. First off you're just getting to where it gets fun. Win those big ol boars play games and you can outsmart them is when baiting is at its best. What are you using for bait? I would highly recommend sweets, and stay away from meat. Think of it like this: when you sit down and eat a big ol T- bone you usually end up feeling like you ate too much and just wanna go take a nap, but if you'r hungry and eat a cookie you constantly find yourself going back to the kitchen for just one more. Just like humans a bear will get that short sugar high and keep going back more often to get more. One of the best things you can have is multiple bears competing for the food. If you've got that, great. If not, make it seem that way. If the opportunity presents itself and you can find bear ##### from another bear. Pack it into the bait site. Its gonna make it seem like theirs more competition for the food as well as make the bears curious to find out who else is in the neighborhood.
Don't be afraid to make noise when you bait the site. The bears already know you're there, so go in bang around, stumble out and slam the truck door. It's just like a dinner bell. This also helps if you can get a buddy to help out come kill time. Both go in and while you get set up to stay let him do the baiting and leave making the same normal noise. The bears will think you're gone and come in. What we found was most the bears would come in within about 20 minutes of the person leaving. I think they often watch you dump the bait and leave.
As far as little gadgets from dusk to dawn. Try some solar yards light. Where you're two hours away they can do the work for you. They'll come on at dark making an unnatural light and they're pretty unnoticeable during the day. They're pretty cheap but remember that just like trail cams bear get curious and break things. So don't spend money on fancy ones and try to place them somewhere that wont be as prone to get chewed up.
Now once you get to hunting if you think the bear has pinned you while sitting the location and that's why it wont come in while you're there... try leaving an old t-shirt there when you're gone. Then when you go to sit remove the t-shirt and set up in a different spot.
