ZoneMinder Forums

So I've been using Zoneminder for a long long time. I have been using 1.32 recently for a couple years without too many issues. I installed a new Ubuntu 20.04 server to try and test out 1.36 (installed 1.36.4) only to find that pretty much all my cameras do not work. (the ones that I don't know I haven't tested yet). Using the same configurations I had in 1.32 don't work at all or give some weird errors I don't know what to do with. For example:

Camera: Amcrest 841b v3 (brand new, works great in 1.32)

I've tried a fresh system install a couple times, followed all the walkthroughs on setting it up I could find, no success.

So what's the deal? Why am I having such problems with the brand new version of ZoneMinder when it works in 1.32? Why is this progressing backwards?

Do you have MaxFPS or AlarmMaxFPs set? If so clear them.


Not sure otherwise. Need debug logs.

I have a bunch of Amcrest, can't speak from experience about the others. All my Amcrest are working nicely (with some PTZ issues, but that's unrelated here). My "source" lines in my Amcrest monitors all look like: Please try this, noting the port number.

I've tried it both ways. Can you tell me what logs you need and how to get them?

I have most of them set to port 80, but I've tried your suggestion with no success.

I would be looking at a network issue. I have setup 4 different servers on various versions of ZM and various versions of Ubuntu and lotsa different Amcrest cameras and this has worked on all of them.

Can you ping the cameras? Can you run a browser on the server? Try going direct to the cameras that way, see if you get response. If you cannot run a browser, you probably can use CURL to poke at the camera and see if you get response.

The error that I'm focusing on right now is the "Invalid data found when processing input". Is there a way to get a log of what that data is and why Zoneminder thinks it is invalid? I've tried turning all the logging on to debug and enable debugging, but it doesn't seem to give me any more information than that.

To add more to this - I seem to have the same issue when I tried it with 1.34.26 as well.

What changed from 1.32 to 1.34/36 that broke everything?

Run some tests with ffmpeg or VLC from the server machine.

I found my issue. Seems something changed in my network that by default it got some weird DNS if I don't point it at my local DNS server. This was not how the previous system functioned, but after changing my resolv.conf I've been able to get cameras to start working.

Thanks for all the suggestions and help!
