In short yes a high set will work fine, but like mentioned above you will have a play with it a bit to make sure it's sensing where you want it so aim it a bit more tricky. Trail sets I have best luck setting the cam at a 45 degree angle to the trail (looking up or down it) as it gives the animal more time in the sensing zone of the cam. Head on movement is hard for a camera to sense due to the way a PIR works (it looks for heat differential across zones). Many of the newer cameras don't do the sleep thing as much anymore, not sure on that model of Moultrie though.

Looking forward to seeing some pics, good luck.
