Events from ANPR camera

[booke02]

Your simple code can help me started with monitoring licence plate data from an ANPR camera. I am not very familiar with python, but hopefully I will manage. I am running on Debian 12 (bookworm)

1. In your main you reference "package io.trzcinski.hikvision" - how can I find that package?
2. You also import "okhttp3.*" but apt install does not find such a package. apt search refers to libokhttp-java and libokhttp-signpost-java so I am guessing that I need those packages - correct?
3. Will I have issues with "import javax.xml.parsers.DocumentBuilderFactory" and "import java.io.ByteArrayInputStream" as well?

Hoping that you can help me,

Thanks,

Keith
