Time plan settings for Loryta (Dahua)LPR in Config tool

[Barnyardo]

Hello there
I have a couple of Loryta 5241-ze12e LPR cameras I am fine tuning for lighting conditions using the Time plan settings menu in the Config tool. I almost have it nailed down(at least for the month of October. I added a couple of front and low luminance profiles (brown and green bars) to the evening schedules to compensate for folks driving with their lights on and of course the dramatic light change between 6pm and 8pm. When I try and add the same compensation profiles to the morning schedule, it won't let me. I can have a max of four bars (Day/Night/Front light and one more(in my case Low illuminance) on any one month.
Just wondering if anyone has experience in the Time plan settings of the config tool that might know if this is indeed the case. Thought maybe I might be missing a command. See the PNG for a little visual of what I have so far.
Appreciate any insights you might have.
Thanks, Bernard

We have seen based on which camera with the new GUI that it will allow 4 or 5 profiles, so you probably are at the limit.

With that said most of us only do 1 or 2 profiles for LPR.

Thanks Wittaj
I was able to go from night-low luminance-day-front light-low luminance-night.
I checked the clips this morning and everything seems like it is looking okay as it is. Might need a little tuning as the seasons (ie California) unfold.
I do have a question regarding splitting zones on a street that has lots of shade on one side and sunny on the other(or for that matter, a shadow splitting the street in the direction of travel).
Was wondering if this can be compensated within Blue Iris or not.
okay, thanks again.

Within BI the image itself cannot be adjusted, it simply takes whatever video is fed to it. If you are talking about motion detection, yes some of that can be mitigated in BI.

Do keep in mind that of the goal of the LPR camera - to capture plates. Everything else is secondary. So we really don't care about horribly lit images as long as the plate can be read. One of the reasons why some just run it 24/7 in B/W on one profile.

Thanks Wittaj
I was more concerned about a car's License plate coming through the shaded area and into the blinding sun where it gets washed out. Looks perfect in the shade but as the shade moves and shrinks during the day, the window of visibility shortens.
Also I get two way traffic where I can see one car's plates in the shade very well but the traffic going the other way in the sun gets washed out. So yes, it's more of an exposure issue than a trigger issue.
I've compensated the exposure to try and get the best of both worlds.
Thanks again
