Lone Wolf used to make an excellent tree seat, would strap to the tree and cam over to secure it. HAWK and Summit both have similar products but just aren't the same, but I'm sure they'd work fine. Hanging off the side of a tree at ground level can make you stick out like a sore thumb, so be very aware of your backdrop and movement. Maybe set up some cover around your feet, and behind you to break up your outline if possible.
