If you chose to set a camera you might want to read some old trapping books about how there used attractants to lure a cat.

If you set up over those deer carcasses you will waste a lot of film on B.S.
A single feather glued to a light fishing line an tied to a swivel placed in a open are will work at catching a cats eye from a long distance without drawing coons & possums.
Good luck a good picture would be worth some serious cash to the right people.
