Package Description for License Plate Recognition (LPR)

Real-time recognition events are received from a camera using either the VAPIX or ONVIF protocol. These events provide relevant information related to license plate recognition, without including the actual image data. To learn more about the usage and implementation of these protocols, you can refer to the Axis VAPIX Library at https://www.axis.com/vapix-library/#/ and explore the "Event Data Streaming" section.

When subscribing to the LPR events, the following data is sent to the subscriber:
