LPR Analysis Event Webhook JSON package

Hi,

Can somebody give me an example of the JSON content received when an LPR Analysis event happens (A license plate is recognized) and sent to the Webhook endpoint?

I have only seen the JSON for the generic event - but i need what extra fields are in the LPR Event JSON package

Am I really the only one using Webhooks to receive LPR Events from XProtect???

:wink:

Well…., a few hints

As described in this manual Administrator manual - Milestone XProtect® Webhooks 2025 R2 the payload of the HTTP POST is an application/json object with Event as BaseEvent (serialized to JSON) of the event that triggered the rule.

However, I see no LPR Event sub-classed of BaseEvent as documented here: MIP SDK Documentation .

My final hint would be to try it out (!) potentially by implementing some of the platforms or code samples in the referenced Webhooks Administrator manual.

Hi Hans, well I wanted to try out the LPR Event message locally on my developer PC - but it seems I cannot “Test” such an event

I need to attach cameras to the computer in order to make a LPR Test event?

Is this really true?

Yes, LPR works in a way where the events have a camera as “source”.

How can I attach a simple camera and make it look at a license place in order to test a real LPR Event JSON package?

One possibility is the StableFPS driver which is a good tool, and further along the way I could envision you having a video of vehicles that can be detected.
