I'm no pro when it comes to videoing hunts but I have gotten a few successful hunts on tape. To answer your questions:

1. Most of todays cameras will work fine, however, a camera with a LOW lux factor will pick up better in low light conditions so make sure the camera you choose has a decent zoom, and a low lux factor.

2. I have found that getting in the same tree or one right beside the one the hunter is in works the best. Also, make sure that the camera man is above the hunter. As a rule, we place the cameramans platform about 2 feet above where the hunters head is when he is standing up in his stand.

3. Just remember, you'll have double the movement so make sure your set has ample back cover to hide you guys. You'll also have double the scent to control, so take all the necessary precautions to be as scent free as possible.

Theres nothing like getting a hunt on tape, the memory will last forever. Best of luck to you!!
