One would have to first subtract the expected peak values of the sensors noise (snow if you will), either by a running average obtained by frame addition on a pixel by pixel basis. Somehow, that seems to imply a decoded stream. And thats obviously not going to be anything but cpu intensive too. So I'm less than enthusiastic that its a workable solution unless one is able to dedicate a machine to that job exclusively. X10 FIR's like the EagleEye or HawkEye will need to be used to detect when the recording should be started (and stopped)
