These S2, S3 versions on all these cameras coming out are probably @Wildcat_1 improved FW updates, lol.

Haha, thought I missed that didn't you
I'm pleased to say that there are some FW improvements making their way into the new S2 / S3 variants, which while based on iterative chipsets do rely on a lot of the same back end algorithms that we've discussed here, fed back and looked to improve 
I haven't seen anything like that happen to a normally functioning camera. So I assume the sensor is indeed a little bad. Edit: But others say it is normal for this cam...
Nope, that is just some overzealous pixels trying to provide an image on something all black. It is documented in this thread and the 4K/T thread this phenomenon with the full color cameras trying to push the limits.
Here was one thread/post showing this that on a black image they show up, but not on a green, thus it isn't a dead pixel, just a few overzealous pixels trying to produce an image in what it thinks is a dark environment.

I started tweaking my new It may be dead pixels, but could also be the new firmware getting a little aggressive trying to make a visible image and a few pixels went rogue. We saw this with the 4K/X when it first came out in lower light conditions. It would be interesting to try it with light...
What camera do you have? The 4K/X does not have, nor can it see infrared.
What is your end goal for these cameras? They are surveillance cameras, not go pro or cameras for Hollywood movies. A few overzealous pixels trying to overcompensate for a dark area is not going to break the ability to get a capture of a perp breaking into your car. The other option is for Dahua to tweak the camera to be more sensitive to light and thus would be a much darker image and not perform as well at night to stop a few overzealous pixels.
And if it is for pornhub, I doubt people would notice
That is a totally different camera than this thread. That is a budget camera that is 8MP on the 1/2.8" sensor designed for 2MP, whereas the camera in this thread is 8MP on a much larger 1/1.2" sensor. Please no more posts in this thread about a different camera than this thread is about.

Greetings all. After reading through this entire thread over the last couple of days I have some questions. I am seriously considering getting an IPC-Color4k-x for my garage. Currently I am using a very crappy Reolink camera before I knew better. At night it stays in full color because there is a flood light on my back porch that points directly at this camera. Thankfully it does not blow out the image.
So here is my first question. With the sensitivity of the sensor on this camera, would the image likely get blown out by the flood lights from my porch?
I did notice in the original test footage that @Wildcat_1 did, his shirt would get a bit blown out when he stepped in front of the flood light.
My second question is for @EMPIRETECANDY
Is there still a chance that they will be releasing a varifocal version? If not I would likely go with the 2.8 lens since that is where I currently have my POS Reolink set at.
Thanks in advance for any advice and help on this. I truly appreciate all of the work everyone on these forums does for the community. I've learned more from this group than anywhere else.

Any cameras better not install too close to the floodlight, this camera have great low light capacity using its own led illumination.
There is no plan for a motorized 1/1.2cmos full color camera. So you are using reolink 2.8mm work, just switch it to 4K-X 2.8mm.

Thanks @EMPIRETECANDY . The flood light is between 30 and 40 feet away and they do point towards the ground so not pointing directly towards the camera location. I was trying to see from other on this thread and images they posted if there was ever any blowout of the image. Saw a few that did deal with light in front of the camera, but it only seemed to reduce the image at further distance. Wondering if anyone by chance ran into any issues with too much light in front of the camera.

That would be OK, the camera angle is easy to adjust, just not watch directly to the light then fine.

Only real concern, as long as its not pointing directly at the camera, is a backlight condition. If you have a lot of light facing the camera, objects between the light and the camera will be backlit and be dark facing the camera. You could mitigate that by running the onboard LED's which of course would be facing out away from the camera

I was actually considering picking up some smart floodlights that I could dim a bit if needed. Currently the bulbs I am using are dumb 100W bulbs.
Thankfully in my current setup I don't get a lot of backlight on objects in front of the camera. The camera is at about 7.5' off the ground and the floods are about 15' above ground pointing downwards. The floods have worked great at illuminating the cars and allowing the ability to see into them. The LEDs on this camera would probably help a lot if I do end up with any backlight issues with the more sensitive sensor.

That's worked well for me. I have the Hue lights all over so I went with Hue floods. Lets me set them at whatever level I want and I can trigger them from motion sensors. The 4K-X handles the lights coming on brighter very well. No flash, just an increase in the light level. I keep them very dim most of the time with some other accent lights since I don't want full floods on all the time. That's still enough to have a pretty good image. When triggered they come up to ~50%-75% which lets me pick up whatever motion better and then they dim back down after some time. I have one pointed more near-field and the other lighting up the background more. Don't use the on-board lights. At least with the version/firmware that I have that causes some internal adjustment in the cam so that the image is more 'tunnel vision' for lack of any better term with a brighter area in the center and darker around. Much better when just left off.

There is a huge difference in FW.
I have one with the original? 2021 fw and am able to dial it in pretty well with one very old very weak street light.
A newer one with late 2023 fw aimed at the same scene (diff angle) is so over sharpened, so much digital noise that I just took it down and am replacing with a 5442
Unfortunately the camera won’t allow upload of the older fw

Is there a way to configure this camera to follow the varying changes of dusk and dawn? I see I can set the day and night profile to a specific time every morning and evening, but really want it to change based on the actual dusk and dawn times that change pretty much every day.

Thanks to @EMPIRETECANDY and through this forum post
https://ipcamtalk.com/threads/dahua-day-night-switch-utility-dahuasunrisesunset.18205/, I was able to get this worked out through Blue Iris. The forum post help with the bullet version of this camera but did not for the turret version. Andy provided the following for the turret version to switch between day and night profiles:As always, I really appreciate everyone here and the great work you do.
The API was posted in the turret review thread as the 4K-X and 4K-T are different GUIs and thus different APIs. I thought we had the APIs for the newer cams in the sunrise/sunset thread, so will have to take a look and add if not.
Worlds First Review - Dahua DH-IPC-HDW5849H-ASE-LED / IPC-Color4K-T - 2.8mm Turret
Interesting. Let me try those. Did the two cameras that this API worked for using the new GUI or the old GUI? IPC-Color4K-B180 (PFW-5849-A180-E2-ASTE) also use web5.0
