Processors running on PanaCast 2 perform advanced stitching and rendering algorithms. The new PanaCast video processor on board processes 300 megapixels per second internally but the whole system requires less than 5W of power. That makes the camera warm to the touch, but within safety operating requirements. PanaCast 2 processes 4.15 megapixels per second output resolution.  Other cameras have essentially no processing in them so tend to run cooler.
