Thanks genius3000 & kirjoitti for your suggestions using web control.
If I got your right you are suggesting something like this:
## Start Configfile snippet
# add at configfile of camera-1: (camera-1 is Motion-detect-master-camera)
# At Start of event of camera-1:
# Start with "motion web control" event for camera-2:
# {IP}:{port}/{camid}/action/eventstart Trigger a new event.
on_event_start??? curl http://localhost:8080/2/config/eventstart
# At ende of event of camera-1:
# Stop with "motion web control" event for camera-2:
# {IP}:{port}/{camid}/action/eventend Trigger the end of a event.
on_event_end? curl http://localhost:8080/2/config/eventend
## End Configfile snippet
As I am only interested in events of camera-2 that get triggered by webcontrol,
I could configure the motion-detection of camera-2 that it is never starting a
event from its own,
maybe by giving it a mask-image that is completely black....
mask_file /etc/motion/Mask_kamera2.pgm
What I didn't understood is the "multiple triggers logic" that genius3000 is
mentioning.
Does it means a logic that avoids that the event gets triggered multiple times ?
e.g. that cam-2 is starting a event on its own and gets additionally
via webcontrol a signal to start cam-2 event ?
Anyway, I will test it out, but the suggested sollutions sounds already great,
thanks a lot!!!
genius3000:
I am actively using this with the scripts.
Not through on_event_start though, I am utilizing inotify
- i.e. Script trigger to the first image stored by motion.
Using inotify I can avoid multiple triggers logic that is
needed with on_event_start.
I am using ALL for the url {IP}:{port}/ALL/action/eventstart1.8.2022 6.23

I have never done this but in theory you should be able to use the
mentioned "on_event_start" and "on_event_end" along with the
webcontrol (interface set to 1). Have a read through the guide
section -
https://motion-project.github.io/motion_config.html#OptDetail_Webcontrol.
Snippets of the event start and end using this:
? {IP}:{port}/{camid}/action/eventstart Trigger a
new event.
? {IP}:{port}/{camid}/action/eventend Trigger the
end of a event.
Safest thought would be to have camera1 trigger the event start/end
of camera2 in this manner. I'm not sure how motion may react if you
happen to externally trigger an event while one is already happening
(could test it out). With some external scripting one could track
motion/event states and react accordingly, still using the
webcontrol.

A alternative to the above would be:
- Any motion at camera1 should trigger the recording process of BOTH cameras
(camera1 and camera2) .
