I know if I was a poacher (which I am not
) and I saw a cam I would definitely do everything do get it because of the evidence on the cam...even if I had to cut down the tree or completely destroy the cam and card inside. If you do use a cam, make sure that there is no flash for the night. You may even try putting a stand up one night and sitting in it and wait for the to come by and get them that way...
