Axis License Plate Verifier analytics
In Progress
We have a customer with an Axis camera, named Front Driveway, running the Axis License Plate Verifier (ALPV) and creating bookmarks in NxWitness. However all the bookmarks just say "ALPV.AllPlates at Front Driveway (IPNUMBER)". Are there ways to use variables in the tag creation to insert into the bookmark the OCR'd tag number and the cropped thumbnail of the tag which is generated by the Axis camera?
According to the Axis API documentation the camera should be sending something like this sample data with the "text" field holding the license plate number.

Regarding the thumbnails, the ALPV software settings has an option to Do not send images through HTTP POST, which implies that it is sending images by default, but I don't know how those might be transmitted or received.

Hi Jeff Jones,
Currently, the limitations are known.
The good news is that our developers are improving this feature, and we aim to provide this feature in a 5.0 patch. Unfortunately, I'm not able to provide you with an accurate release date.

Hi Jeff Jones,
Currently, there are no updates, and we still aim to provide this feature in a 5.0 patch, but which one isn't clear at this moment, since we encounter some challenges which might result in postponing the feature to avoid it blocks all progress.

Hi Jeff Jones,
I'm really sorry to bring you this news, but I just got some disappointing news.
We weren't able to add the LPR functionality into the 5.0 engine. Our integration team will start to write an entirely new engine for the LPR functionality, but as a consequence we have to postpone the Axis LPR integration and won't be able to deliver it in a 5.0 patch.

Dear Scott Barrett,
I hope this message finds you well. I would like to provide you with an update regarding your inquiry. Unfortunately, the situation remains unchanged at the moment, and we do not anticipate any immediate changes in this matter.
I would like to take this opportunity to inform you that we aim to delivering a solution in version 5.1 or 5.1 patch.
