I have been using the 5241 for many years strictly for LPR duties. I have had day time dialed in since I got it but night time is hit or miss. I am trying to set the night mode to B&W and when I do that, it just changes back to auto. I have tried this in IE 11 and Chrome but it does not seem to save. I have tried switching to "Full Time", hit save, go back to the night profile, switch to B&W, hit save. Then change back from full time to "Day/Night". And it reverts back to auto instead of B&W.

I use the "schedule" profile.
While I think the "Day/Night" profile will work, the problem is that it decides when to change based on the light sensor. When it does, its often too dark for the camera to focus properly and you end up with an out of focus LPR cam. The same can happen changing from Night to Day.
Using the Schedule, I set the Night profile to come on approx 45 minutes before sunset and back to day 30 minutes after sunrise. This insures adequate light to focus. Yes I have to adjust this 3-4 times per year to account for the seasons. Its not a precise thing that has to be done more frequently than that, and it takes 5 minutes.
The alternatives are
1- Leave it in B&W both day and night. If only for LPR, it shouldnt matter in most scenes.
2- Use the SunriseSunset utility

interesting problem.
I think I'm running "Night" profile full time. with Ir Illumination set to auto. and I'm trying to think if I selected B&W...but i must have because it's B&W 24/7. The main result is that it's not focus hunting anymore.
My other cams can get a look at the vehicle. Esp, if they drive around back and get lit up by 3 cams in back.

So what happens in the 45 minutes before sunset when your cam goes to night profile and its not 'dark' yet? Does it still capture plates? The issue with mine is if it switches over before it's actually dark, then I don't think I get any captures because of the high (1/2000) exposure setting. Its dark and I don't think it reflects IR during daylight? Does that make sense?

It does, just not as well. I have IR on manual 100. Let me grab some caps and let’s see!

So starting while still good daylight to about 45 min after sunset (which is 20:17 currently) from last night.
We had storms popping up in the area from about 6pm on so light conditons were all over the place with lightning, dark clouds, light again, dusk, etc
Notice also my angle sucks in that the street runs due east/west and at dusk the camera is staring into the west sun which also means very dark on the plates going away from it.
Notice the 2nd capture (last one on day schedule) is not great, still in color (I had it changing at 19:30)

And for reference, here's the 5442 6mm overview camera, which has not changed to night settings yet and is struggling, matched to captures 3,4,5, and 6 above
So pictures 3,4 and 5 are all on night profile but its still semi daylight? As soon as I switch to night profile I go dark due to exposure setting.

I did have HLC on for night. I'll turn that off and see how it goes.

My daytime and nighttime focus/zoom are slightly different so I have a rule setup in my home automation system (Hubitat) that changes both the profile and the focus/zoom based on sunset and sunrise.
Yep, either use the utility or the commands in BI. Both options are presented here:
Dahua day/night switch utility - DahuaSunriseSunset
I wanted to use stronger noise reduction at night and weaker during the day, but Dahua seems to have made a mess of the profile management. On most cameras, there doesn't seem to be a way to have the camera switch automatically between Day and Night profiles when the camera changes between...
Personally I use the utility.

Another quick test series from last night. bad storms again, but the 'transition period" shows good results and camera holds focus well after dark.
Sunset 20:17 - series begins at 19:40, camera switches to night profile at 19:30

I monitor 4 LPR cams but the other 3 get very little traffic. Two are in much darker areas but all run the same base settings with a little more gain and/or Iris on the dark ones.
