I was hoping that I could get some help fine tuning my LPR (HFW5241E-Z12E) I've been going from good to bad trying the suggestions that I seen in other posts. One night it looks good and I can read a plate but the next night I can't even see a plate on a car. I did have problems maintaining a focus point but I got that worked out using the DahuaSunriseSunset app and I used the suggestion of refelective tape to focus the camera. I live on a Cul de Sac so I only get a few tries a night but I will drive my car up and down the road to check changes. Thanks in advance!

Being on a cul-de-sac, I would drop the FPS down or if you want to run at 25 then up the bitrate. I get plates at 8FPS and they move past my house.

Turn off Smart IR.

Drop sharpness way down. Like try 20. I think that is your biggest problem.

Match the 3D and 2D - try 35

Contrast usually is a little higher than brightness

you could try manual shutter of .75 which is 1/2 way between 1/1000 ( 1.0) and 1/2000 ( .5) (1/1500)=.75

I'm not sure of the distance, it focused just past the start of the Cul-de-sac. The zoom is 1140 and the focus is 920

Keep dropping sharpness. I run one of mine at like 4
Do you keep your sharpness at the same level during day time? Or do you run the night profile at all times? I recently got the IPC-B5442E-Z4E from Andy and I am trying to maximize readability of license plate captures.

It is pretty low for day and night. I figure since all I care about are clean plates, I want the plate to pop off the screen and taking all that sharpness dots out of it gives a nice clean plate.

THe sharpness during the day is 50, I don't have any issues reading plates during the day.
