"How about using these cameras as target practice?"
in britain they are mounted on a 2m tall pole.
in the states, they are a good 8m up on the light pole.
the cameras here are also about 2" square as opposed to britains which are about a foot square.
bit tougher here.
12 Gage, No 5 bird shot. You do not need to aim all that carefully. Just point in the general direction.
