Thanks!

I've built a new Ubuntu 18.04LTS server and installed Apache, PHP, MariaDB and Zoneminder 1.32
I now want to migrate Zoneminder from the old server to the new one without losing any events etc.

Is this an easy/possible thing to do?

Thanks. I've updated the offending fields with NULL

Yes, the three cameras that used to be linked have a value in the LinkedMonitors field.
I have restarted ZM several times since I deleted the linked cameras.

I configured three of my cameras to modect and low res and then linked the high res version of the camera as nodect. I have since changed the config and removed the low res version of the cameras and removed the high res camera link to them. The log file now gives regular warning messages saying the ...

Why do my HikVision cameras do this fairly regularly?

I have a low res camera running modect and a linked high res version of the same camera running nodect. It appears that close-together events triggered by the low res camera are not recorded by the high res camera. For example, if two events are triggered close together, I only get the first one ...

That's correct I believe. All modes apart from "None" are capturing. Capturing doesn't necessarily mean recording.

I think I may have answered my own question. It seems that if I change any config parameters on the low res camera I need to unlink and relink the high res camera to it again. Not sure if there is a good reason for this but it does seem to fix the problem.

Thanks. I've configured that. I have a camera set to low res and modect, a clone of the same camera set to high res and nodect and linked to the low res copy of the camera.
The low res camera picks up movement but the linked high res version doesn't record any events.

Is it possible to detect motion on a low resolution and record events on a higher resolution?

I have a camera without IR and I therefore want to turn off Modect at night. Can I do this via cron?
The nice-to-have would also be to turn it on and off at sunrise and sunset and then it would sync with the changing daylight hours during the year.

thanks

Can I just install Python3 on a Ubuntu 18.04 server running ZM 1.32 or do I have to do something with the running version of Python2 first to ensure that ZM keeps running?

For my purposes, I don't need anything too clever so I've ended up with this short script that does the job nicely. I've set the camera to 1fps to keep the volume of data down a bit. I've set ZM to just record frames and no video. I'm using the camera to record plant growth so I only take one frame ...
