Just circling back around on the S3 cams. I submitted an exhaustive number of bug fix requests + AI algorithm and camera behavior changes on this one. 10 key ones I have been tracking and I'm still working with Dahua on getting these integrated. I can post the issues I found here for reference as well as some under the cover changes to out of the box defaults I've also submitted.
For the out of the box camera settings improvements (non algorithm related) I am currently trialing a beta FW that I'll look to have @EMPIRETECANDY and Dahua push to wider availability soon.
Thanks

I'm sure I wouldn't be the only person curious to the your list of issues.
Glad to hear they are getting feedback form 'ya @Wildcat_1 and rolling 'em into future firmware.
A big Win-Win for the users/community and the vendor.

I installed seven 5442 S3s over a year ago around the perimeter around my house, and now I'm wondering if I should've gone with the 5482s. My cameras are primarily "overview" cameras to detect humans or animals. I feel like the extra MPs would allow me to better make out faces, vehicles, etc. Wildcat's video of nighttime quality of the 5482 shows it's pretty damn good. Change my mind.
I ran a 5442 S2 and 5842 S2 side-by-side for a few weeks. I agree the 5842 was pretty good at night, but the 5442 still beat it. It's a pretty simple tradeoff of prioritizing day performance vs. night performance. When you're greedy like me it's a tough choice.

Let's talk about nighttime performance. If the camera goes to IR anyway, what's the advantage of the 5442?

Same. 5842 S2 isn't bad at all but the 5442 S2 is noticeably better low-light. Especially at the margins of lighting and with movement. Haven't tried the S3 but I'd think the same likely applies. The practical difference in what you can resolve isn't as much as you might think (i.e., it's nowhere near 2X better) and if you introduce more blur or noise then you just have a worse image at higher resolution. Daylight it's great but I really don't see that much difference in what I can resolve between the two.

5442 S3 is clearly better picking up light (IR or white) at night than the S2 FWIW
As others said, buy one and do a side-by-side and see what you think LOL. Personally for me at the distances I was looking at, the 4MP was better with the lower light, even running infrared. Granted mine was the Z4E, but it would be comparable. You can push the 4MP a lot harder than the 8MP in lower light conditions.

This is the way I look at it, and I'm only talking about my specific needs here. For nighttime, I'm primarily concerned about alerts on human behavior (plus animals for fun). I fully expect I won't see their faces clearly to identify them, but more to know they were trespassing and seeing what they were doing and where they were going. I feel that if you wanted to identify faces, license plates, serious levels of detail, you would need a $2k PTZ camera for that purpose. I may go that route at some point if I had a bunch of crime, but I live in a super safe neighborhood.
During the day, however, it would be nice to get crisper detail because there's simply more benign activity I may be interested in.
Not sure if any of that makes sense, but it's a conclusion I'm coming to after getting into this hobby a year ago.

That's a good comparison. Indeed, even in IR mode, the 5442 is crisper.
Since you have the S3s, personally I wouldn't deviate from them.
Maybe you don't have enough experience with 8MP cams yet, but these cameras are not like DSLR cameras and more MP isn't necessarily better.
Many here feel 4MP represents the best overall option.
The 8MP on the 1/1.2" sensors do provide great OVERVIEW to capture color with little light, but until they make those in varifocal, most here including me will be sticking with the 4MP.
But the 8MP on the ideal 1/1.2" sensor doesn't have animals as an option yet.

At the fringes, the 5442 will show an identifiable image where the 5842 will show an unidentifiable blob. And when the 5442 is showing an unidentifiable blob, the 5842 won't know anything is is there at all.
The 5842 S3 Zoom is terrible at night. Stick with the 5442 unless you literally have tons of light. The 8mp 2.8mm is better at night than the ZOOM model, but darker than the 5442 2.8mm (it has a real digital zoom though, blows away the 5442 in good light). Since you have a bunch of 5442s you can always just install 1 of the 5842s for a certain area that needs the higher res in the day. Also in many cases you can get a decent image with the 2441 that you may not even get from the 5442, especially in the day. And on all these cameras you can mod the exposure to say 1/10 and high gains but with the 5842 S3 Zoom it gets very soft so its not much use. To compare I modded an Amcrest $57 mini vandal dome down to 1/10 and it has barely any motion blur but sees twice as bright in low light color (wont compete with the 5442 though). It really varies per camera.
