Automatically Start/Stop Motion Activated Camera When Cellphone Not On Local Network
Note: This Systemd service will detect if your mobile phone is on the local network using ping, therefore, it should have a static IP address when it connects to your Wi-Fi network.

Commands to start the service and check its status:
systemctl --user enable surveillance-system.timer --now systemctl --user start surveillance-system.timer --now systemctl --user list-timers systemctl --user status surveillance-system -
I hade issues where the phone would not connect to Wi-Fi fast enought when I was in range of the router, and it helped when I did this:
In LineageOS 18.1 > Network & internet > Wi-Fi > Wi-Fi preferences > toggle On: Turn on Wi-Fi automatically: “Wi-Fi will turn back on near high-quality saved networks, like your home network”. (unfortunately, this requires location to be turned ON, also)

This will be achieved using the great softwares motion and ffmpeg.

Setup pass on multiple computers
Instructions:
-
Create GPG Key
gpg --full-generate-key gpg -k gpg --export-secret-key 6002450973C62F2FD9F8353101C4ECCB53ACCE05 > key-gpg-pws.privateNote: Copy the private key to all of your devices.
-
Initialize git repository on first computer and gitlab (create new project on gitlab first)
pass init 6002450973C62F2FD9F8353101C4ECCB53ACCE05 pass git init pass git remote add origin ssh://git@gitlab.com/username/pws pass insert email/gmail.com pass insert forum/reddit.com pass git push origin master -
Setup additional computer
gpg --import 6002450973C62F2FD9F8353101C4ECCB53ACCE05 git clone ssh://git@gitlab.com/username/pws ~/.password-store
Compatible client list can be found at: https://www.passwordstore.org/ (including ones for Android and iOS)
Note: I will probably go with Bitwarden or KeepassXC instead because this one would not encrypt the paths to the passwords…

If the internet is not working in your Gnome Boxes/qemu virtual machine guest after replacing the firewalld service with the iptables.service in the host OS, it might be because the iptables rules relating to the virbr0 interface and the 192.168.122.0/24 network are missing.

Start motion software on Linux computer
-
Start the Bash script on the Linux computer for monitoring for new image files in /tmp/motion/ and automatically emailing them to you.
You should now be getting 1 email per image captured when motion is detected.
I changed the camera resolution to 1280x720 and the motion config setting “treshold” to 750, to increase sensitivity.

- Using a sharpie, identify Ziplock bags with palm type, date, etc…
- Add humid dirt to Ziploc bags (not too wet or the seeds will rot)
- Add seeds to bags
- For queen palm seeds, I have had better luck so far with orange seeds that just fell off the tree (as opposed to green seeds that I cut off the tree).
- Set the bags on a shelf at room temperature (they don’t need light)
- Wait from 1 to 6 months (no need to add water if you keep Ziplock bags sealed)
- Transplant germinated seeds to pots
The sprouted seeds should look similar to this:
