Start with your shotgun unloaded. Loosen the silver screw on your quick-release bracket using the provided Allen driver. Then, position your ShotKam 3 to 10 inches from the muzzle. The lens needs to be at least 3 inches back from the muzzle in order to avoid debris landing on the lens, but you can attach it anywhere from 3-10 inches back that feels good to the balance of your gun.
If your gun has porting holes, then attach the camera about 3 inches behind the holes to ensure debris does not land on the lens and no holes are covered by the bracket. There is no difference in the video quality between guns with porting holes and guns without.
Align the camera straight under your barrel (USB port will be up closest to the barrel). Firmly tighten the silver screw. Watch this quick 2-minute video to learn how to attach your camera to your barrel, and learn when you have to calibrate the reticle.
