Send LPR (License Plate Recognition) data through the Milestone XProtect system to a Client API Gateway.

When Milestone LPR makes detections it sends analytics events to the XProtect VMS. We have a sample that shows how to extract these events. From there I guess you would know how to send the data to your gateway.

The Alarm and Events Viewer sample can do this (notice the LPR Events option)- https://doc.developer.milestonesys.com/html/index.html?base=samples/componentsamples/alarmeventviewer/readme.html&tree=tree_2.html

Can you explain how to send LPR data to our gateway?

No, sorry, I have no idea what your gateway is. If you have questions about Milestone’s gateway (or APIs) I can answer or get answers here at Milestone. Might you have another forum, or people in your network, on how to send to your gateway?
