I seem to always have bears come and investigate my camera's. Countless video's of bears messing with the cameras. Lost one to a bear that was 20 feet in a tree over a wallow... bear climbed up the tree on three different days until he finally broke the strap, then mauled the camera for another two days until it ended up in the wallow.
I came to the same conclusion that they are attracted to the smell, so now I run all bear boxes.
