OK, point taken!
I am going to try this.. Thank you @bigredfishThat same problem is what made me play with Customized Range on Manual Exposure. Start around 0-2 and see how it works..
LOL, I been doing that hahaI have a dumb idea...More Camera's....
What makes me laugh is, if the shutter is set to 0 ms, how is any photo taken. If I'm not mistaken 1/1000 = 0.001 seconds, 1/500 = 0.002 seconds, therefore 1 & 2 ms.Sorry for a dumb question .. What I have not understood is what is it means any chart like in ms..
0~2 is that like 1/1000 - 1/2000 ?
Luckily, I have a second cam (LPR-W) pointing in the other direction. The washout is only an issue for cars traveling NW on that street. Cars that travel in the opposite direction and those that turn onto that street from the side street do not have that problem. So if the car has a front plate, I get it on LPR-W.I have a dumb idea...More Camera's
More cameras is NEVER a dumb ideaI have a dumb idea...More Camera's....
At night I agree. It’s a mess and you have to use a fixed manual value.The problem I had with a range for the shutter speed for my LPR was then it was taking photos every time the shutter changed because it would then cycle through an autofocus and of course then it would be a complete blur when a car came through at that time.
We just have to recognize that for LPR purposes that not every situation is going to be perfect, so we have to find the balance for our system. For some it is an issue at dusk/dawn times frames, others it is a washout with a morning or evening sun, and others it is a cloudy day.
Yeah I use it on one of my 4 LPR cams. But because of a tree shadow, I have the opposite problem. On dark rainy days my fixed 1/2000 got too dark for a color image.Luckily, I have a second cam (LPR-W) pointing in the other direction.

Would any of the backlight options help?
@bigredfish I'll try the customized range tomorrow afternoon. It's too late for today.
A trick I think I learned from @Wildcat_1 ?
set to manual, choose your fixed exposure - say 1/2000
Then while still on manual, click the rate drop down and scroll all the way down and select Customized Range
It will do the calculation and insert the right fraction for you!
