Open CV face recognition and alarm

How to make it work

1. You need to source your own credentials for firebase and supabase
2. Implementation here is loading a json file but you can manually feed it to the variables in firebaser.py
3. Make sure to run your file with the directory at the largest folder that contains this readme file
4. Install pip in requirements.txt
5. Ensure circuits and devices are properly connected
6. Setup wifi to automatically connect to internet
7. Setup python file to be executed properly

Editing Raspi files

For Internet

1. open terminal

2. sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

3. paste the following for each network ssid you wish to add and save

   network={
       ssid="YOUR_NETWORK_NAME"
       psk="YOUR_NETWORK_PASSWORD"
       scan_ssid=1
       proto=RSN
       key_mgmt=WPA-PSK
       pairwise=CCMP
       auth_alg=OPEN
   }
   

   Explanation

   • ssid: wifi name
   • psk: password optionals
   • scan_ssid: to connect even if hiddne
   • key_mgnmt: WPA-EAP or WPA-PSK or None or SAE
   • pairwise: CCMP or TKIP
   • auth_alg: default OPEN

4. sudo nano /etc/network/interfaces

5. add code below

   auto wlan0
   allow-hotplug wlan0
   iface wlan0 inet dhcp
   wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
   iface default inet dhcp
   

For Wake Up via GPIO

1. open terminal
2. sudo rpi-eeprom-update && sudo reboot
3. sudo -E rpi-eeprom-config --edit
4. add to bottom of the file. gpio_pin 3 is default but can be changed for other pins (like 7). use only power off is you want complete shutdown

   wakeup_gpio=7
   power_off_on_halt=true
   

5. save file and reboot system

For Auto-running python file from boot

1. open terminal
2. create service

   sudo nano /etc/systemd/system/my_script.service
   

3. add contents inside, change execstart into used python interpreter path and script path and working directory

   [Unit]
   Description=My Python Script Service
   After=network.target
   
   [Service]
   ExecStart=/bin/bash -c 'source /home/pi/myenv/bin/activate && /home/pi/myenv/bin/python3 /home/pi/my_script.py'
   WorkingDirectory=/home/pi/
   StandardOutput=inherit
   StandardError=inherit
   Restart=always
   User=pi
   
   [Install]
   WantedBy=multi-user.target
   

4. save and exit file
5. enter following commands. ensure service name is similar

   sudo systemctl daemon-reload
   sudo systemctl enable my-script.service
   sudo systemctl start my-script.service
   

For Reducing Ports (not recommended during development)
