I replace an older Dahua with IR with this IPC 4K Colot 8mp. I setup Manual Exposure Profiles for Day and Night and set the Illuminator to Off. (I don’t want the white lights on). For some reason it doesn’t automatically switch from Day to Night Profile when it get dark. My older Dahua would switch automatically. There is a nearby light on the garage that is on but I don’t think that is the issue since it was on with the older camera. Is there some automatic day/night switch I am missing in this software?

What do you expect/want it to do at night that its not?
Go to B&W? (you know it doesnt have and cant see IR right?)
Do you have the Day/Night tab set to Black and White for Night?

I don't think the 4K-T can switch profiles without setting up a time plan schedule/setting or sending a command to do it via the API (what I do).
As @bigredfish says, this camera doesn't emit IR and can't see it either. So using it in black and white is of little help. The only reason I need it to switch profiles at night is the street lamp in front of my house is an older high pressure sodium light that emits a horrible yellow. I have to manually white balance the camera for the night profile or the entire video is a horrible yellow color.

I typically run very different profiles night and day on most of my cameras. And like you say, a true day/night schedule profile
Daytime I'll run 0-2 exposure, sometimes WDR if necessary etc...
Night almost always has to run a slower shutter for example

Both are set to Color with different Exposure, Brightness, and Contrast settings.

You need to set up a schedule profile for day and night and force it
Choose Customized scene at top
Then use the day/night colored bars to set your schedule.
(You'll need to verify your settings on each profile (day/night) by using the drop down. When you hit refresh it will go back to the profile you're in at the current time. So if you're adjusting Night, make sure and always go back to the drop down and choose Night before making your settings)

It's also helpful to do a Google search of sunrise/setset times for your location (including when daylight saving/stadard times start and end). Type in the values for each month in the plan, and it will look something like this.

Thanks.
Do you have the 8K? If so would you mind sharing your Exposure settings for Day and Night. I realize ours will be different but just curious.
When I had a couple of the older PTZ's (SD39225XA-HNR), I disliked having to alter the day/night settings each month using IE, so the little bit of pain of about 1/2 hour, entering the values for the schedule for these cams, seems not nearly as difficult. Someday I think I'll write an AppleScript to do it.^^^^
Yes thats the better way.
I'm lazy
As an example, the first pic is the settings for one of my 4K-X cameras, and the second pic is the settings for a 4K-T camera.

Great settings. Thanks for sharing. I am working on getting rid of some jagged lines that are bugging me.
The jagged lines are a result of a higher resolution and bitrate and sharpness and the size of the image.
We have many posts over the years with similar questions and almost every situation it is like this with a fence. But it can be seen with brick walls and house siding as well, and sometimes like in your situation.
I can do that with my neighbors fence based on the size I make the image on the screen. I can actually make that happen with every camera if I make the image small or large enough to cause it.
You can mitigate it some by changing the size of the image on the screen, changing the resolution of the camera stream, and lowering sharpness and lowering bitrate.
The 4K cameras on the 1/1.2" sensor seem to be more prone to this phenomena as well.

I can tell you that with both my T as shown and my two X bullets, Firmware can make a huge difference.
BUT not like you think.
The later 2024 FW sucks. Its even more oversharpened and noisy.
This Turret is running
V3.120.0000000.14.R, Build Date: 2023-02-27
And the Bullets run MUCH better with FAR fewer artifacts and noise with the original 2021 FW. DO NOT UPDATE TO 2024 FW

I'm not following when you say "changing the size of the image on the screen"? Do you mean Resolution?
And IMHO these cameras need a higher bitrate, minimum of 12,000 KB/s and do fine at 16,000. At 8192 they suck.
And yes they are as most Dahua cameras, highly over sharpened from the factory

Your .png is only 2MB, Mine is almost 8MB
Your resolution is crazy low 1334x753 - mine is 3840x2160
No, change the actual size of the image on the screen. Make it bigger or smaller.
Like in multi-cam view, the jagged may show, but not in full-screen, or vice versa.
And yes these cameras need a higher bitrate, but if the jagged lines bother someone too much, they may have to lower the bitrate to soften it more if dropping the sharpness results in too much soft.
Here is another thread of the 4K/T with the same issue that we are discussing here that shows how little changes can have a big impact and that the jagged lines are actually a result of the higher resolution when comparing the 4K to the 720P substream.

I use Sunwait to do it. It adjusts for sunset/sunrise based on location.
