Zoneminder is the world's best video surveillance software. It has amazing features. However, one thing is clear, whenever there is a big update, you can be out for months.
That happened to me. I eventually just took a small computer and constantly reinstalled everything until it worked. It has so many parts that it grinds down the poor little thing. I have to stop the process to do maintenance. I finally got it all working.
It's classical Linux in that all the old bugs are new again. Just keep reinstalling everything and it will work one day. Hopefully, it once again lasts for a year or two.
