Not to offend you but I believe this to be user error. If you set up the cam too close to the subject(run, bait pile or whatever) the sensor will not trigger quick enough. The sensor detects a cone shape area and the closer you get to the cam the small the trigger area is and the more likely the deer will pass by before the pic is taken. Set the cam up 20-25 feet from where you expect the deer to pass by and you'll get better full deer pics
