Ring doorbell 3 pro

I upgraded from a ring doorbell to ring doorbell 3 Pro. Both were battery operated. The night vision on the original ring doorbell seems so much better than the 3. The 3 is giving an almost pitch black picture past about 2 metres, whereas the original was so much clearer. The 3 is in exactly the same location as the original ring and wondered why the night quality is so much worse on the newer model
