man, just my own opinion, take it for what you will, but beefing up security with heavier box etc is not the way to go the way i see it. boxes and chains and python locks and whatnot make them more visible. somebody will cut down the tree if they want it bad enough. only way to keep it from getting stolen is to keep it from being noticed. i say skip the locks and cables and chains and boxes. get a screw in mount like the slate river cam mount and a couple sections of portable tree stand ladder and hang the *censored* 18 feet up. who looks up in trees?
