I am working on adding the option to save OCR training images then users can send me the training images so I can retrain the OCR model to improve accuracy. Most likely I will release a new version in a month or two.
If you want a full color option try the EmpireTech IPC-T549M-ALED-S2. This is what I have at my front door. It is not 4k but has a Min. Illumination of 0.0005 Lux@F1.0 (Color, 30IRE) like the EmpireTech IPC-Color4K-T...
If the model work well I will train a YOLOv8 version. We currently do not have a YOLOv8 .NET module, I am using the YOLOv5 .NET module and are getting better performance then the YOLOv8 module.
I am training a model right now that will identify the make/model of vehicles. I am not sure how good it will be most of the model years are about 10+ years old.

The ALPR module uses the license-plate model first to find the license plates in the images sent. If the module does not find any license plates it returns nothing found. If it finds a license plate then it crops the plate and runs OCR on the cropped plate and send the OCR results.
