So I've been doing more camera research since coming to this site and have been getting some helpful advice. I was pretty much set on getting the IPC-HDW4231EM-AS given the great low light performance. However I came upon the IPC-HDW4830EM-AS 8mp 4K camera and found it enticing. The sensor is slightly larger at 1/2.5" vs 1/2.8" but is also cramming more megapixels in there. Also it is only DWDR compared to true WDR on the 2mp brother. So am I taking a large hit low light quality chasing the megapixel race? I've seen people say that 2mp is all you need and any more that only worsens low light without giving you that much better picture. Am I crazy for having 4K lust and should stay "settled" with a solid 1080p setup? Also I'm not factoring cost in the scenario so just assume the price difference is negligible.
