This is the source code that I use for my DIY Security system in my home.
My home had an ADT BHS-4000 system originally.
(Sorry for horrible camera quality)
This system still had its original sensors and everything, it was just simply unplugged. Around 2022, I replaced the main board with an Orange PI PC+, and that's when this project began. The window sensors simply pass through power when they are closed, and vice versa.
I bought a simple GPIO breakout board, and connected all of the sensors to there.

Build solution in Visual Studio 2022, publish secsys project for your SOC architecture, and create /usr/lib/systemd/system/secsys.service:
[Unit]
Description=Starts security system
After=multi-user.target
[Service]
ExecStart=/bin/bash /secsys/run.sh
[Install]
WantedBy=multi-user.target
Copy the published files to /secsys/ and create /secsys/run.sh:
#!/bin/bash
export DOTNET_ROOT=/root/.dotnet
export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools
# Start systemwide Audio server. This is done on boot to prevent noises from speaker
systemctl start pulseaudio
# Start controller
/secsys/SecuritySystem
# Cleanup
systemctl stop pulseaudio
After that, create /musics/ and /musics/annc/ directories and install mpv. Enable and start the secsys service. I recommend to set pulseaudio dameon to run globally.
