How to talk with an IP cam to get ANPR data?

[Angrigo]

I have an IP cam and I would like to retrieve the license plate when it see something.
Through its web panel I can see it does it but I can't retreive picture, info, programatically.
I tried using ONVIF but I can't manage to subscribe to the event and looking to onvif device manager my event is not triggered. I did not take a look to the SDK because I would like a web based software so I tried: - NodeJS - PHP - Python
The web panel looks like this. image

How can I subscribe to the "recognize plate" event?

the camera is ITC237-PW1B-IRZ from Dahua
