Thanks guys, the flea 3 uses the ICX618 1/4" sensor. I will put that in the review.
Greg the camera that Anthony is using is a trial as I understand it but also better than the flea3. More light sensitive with faster frame rates. I don't know anything about the specs on that camera and I don't really want to discuss it here in a thread that is about the flea3. I would suggest contacting Anthony and asking him about that camera.
