x10 sentinal camera

The x10 sentinal camera is not suited to be an exterior camera as they will have you believe. It must be in the shade or it will overheat. I was told it sounded like I mounted it on an 'urban heat island' and that was causing it to reach 110 degrees and stop working. I told them that since the exterior case they supply is black, that heat island or not, if this thing is in direct sunlight it will obviously overheat.
