What is important to note is that it requires AI
Port for processing

It used to be that LPR only worked well during daytime in UniFi Protect. Now the latest update to UniFi Protect has released and comes with Night Time Plate Detection for all third party cameras (make sure you pay the $200 royalty to Ubiquiti)

Fortunately it is not bogging down UniFi Protect and seems to be gathering detections better than Blue Iris 6

Camera of choice for LPR is any Dahua Z12E

Sorry fat fingered it…
DOESNT work… it’s trash

6.2.83
5.1.8 Port


I don’t even get “motion” alerts. Set the motion to highest sensitivity and it doesn’t pick anything up at night. During the day it works beautifully

Working fine for me | Go to settings and make sure LPR Night Vision is on
I still find Blue Iris having 97% Confidence Interval, but both systems are working simultaneously

Wittaj might be onto something. Unrelated but similar.....>I was tinkering with License plate reading in AI from BI. I wondered if My plates may be too small even though they are clearer than Arjuns.
Of course I probably have some setting wrong, but no time lately to mess with. So who knows.
Snow is really messing with plate reading tonight.

Try my custom license plate model it should work better then the default BI model.

Thread 'Blue Iris Version 6 License Plate Custom Model'

After using the built-in ALPR I found the model used to detect the license plate did not perform well at night. I trained a new plates.onnx model that performs well now during the day and at night. Below is the link to the new model. To use the new model save the model in folder C:\BlueIris\AI\models. Then after saving the model restart Blue Iris service.

Recommended min confidence setting
Day 80%
Night 85%

@MikeLud1 ‘s custom plate model is working better than UniFi Protect, that is for certain

Also I noticed my camera zooming a little out a couple of mm’s after sunset. I have corrected the positioning however need to retweak the focus setting.
