You are allowed 1.5 oz. of lure or scent. You can use Anise oil, vanilla, honey, or any sweet smell. I have even used a packet of Kool aid sprinkled on the ground. I have also found they like the smell of Trails End 307 deer lure ( it has a sweet smell). You want it somewhere in front of the camera so he will stop and stay in front of the camera so you can get some pics. They also like the camera's themselves. I think they can hear the very slight klick the camera makes when it takes a pic. I keep my camera's in a metal security box and still had one broken. I get multiple pics like this one every year. This bear actually broke part of the camera that was not protected by the metal box.
