NodeJS server for OpenALPR.

openalpr-server's Issues

Update for latest php forms version

Hi Mate, thanks for this - I needed to update to the following to get it to work. I also removed the "data" element so I could use this as an LPR endpoint for AgentDVR.

If anyone wants a free alpr for AgentDVR then use this. Wonder if search results pick up comments?

And sorry - code tags not working for some reason....

New feature: Support POSTing image data

Rather than providing a URL that downloads the image, also support accepting image data over a POST request.

Concurrent requests unsupported

If you make two requests at the same time, you get the following error response:
