Hi Ted,
To start Motion on reboot, I have "@reboot motion" in my crontab.
I wrote a couple simple scripts to operate three camera machines and a
fourth machine (also a Pi Zero) that serves to archive the captured videos.
One script just uses rsync to send the video files to the archive
machine. This runs on the three camera machines, and is started by the
on_movie_end parameter in the config file.
A second script runs once a day on the archive machine, started by cron.
It creates a directory, moves all the video files collected that day to
it, stops Motion on the camera machines, deletes all videos on the
camera machines and retrieves the motion log, then restarts Motion.
The whole setup has worked quite well.
Jack
