npm run dev

Build for production

npm run build ```

🌐 Static IP Configuration

Windows

1. Open Network Settings: Windows Key + R -> ncpa.cpl
2. Right-click your network adapter -> Properties
3. Select "Internet Protocol Version 4 (TCP/IPv4)" -> Properties
4. Use these settings: IP address: 192.168.1.10 Subnet mask: 255.255.255.0 Default gateway: 192.168.1.1 DNS: 8.8.8.8, 8.8.4.4

Raspberry Pi OS (Linux)

Method 1: For newer versions (using dhcpcd)

1. Edit dhcpcd configuration: bash sudo nano /etc/dhcpcd.conf

2. Add these lines: bash interface eth0 # or wlan0 for WiFi static ip_address=192.168.1.11/24 static routers=192.168.1.1 static domain_name_servers=8.8.8.8 8.8.4.4

3. Restart networking: bash sudo service dhcpcd restart

Method 2: For older versions (using interfaces)

1. Edit the interfaces file: bash sudo nano /etc/network/interfaces

2. Add these lines for Ethernet (eth0): bash auto eth0 iface eth0 inet static address 192.168.1.11 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4

Or for WiFi (wlan0): bash auto wlan0 iface wlan0 inet static address 192.168.1.11 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

1. Restart networking: bash sudo /etc/init.d/networking restart

2. If using WiFi, make sure your WiFi credentials are in /etc/wpa_supplicant/wpa_supplicant.conf: bash sudo nano /etc/wpa_supplicant/wpa_supplicant.conf Add: network={ ssid="Your_WiFi_Name" psk="Your_WiFi_Password" }

📌 GPIO Pin Configuration

• Smoke Detector: GPIO 17 (Physical Pin 11)
• Alarm Bell: GPIO 18 (Physical Pin 12)

🚀 Usage

1. Start AI Service on your high-performance computer
2. Start RPi Server on your Raspberry Pi
3. Start Frontend application
4. Access the dashboard at http://localhost:5173

🔧 Configuration

Default ports: - AI Service: 5001 - RPi Server: 5000 - Frontend: 5173

Update the connection settings in: - ai-service/config.py - rpi-server/config.py - frontend/src/config.ts

🔍 System Monitoring

Access the dashboard to: - 👀 View real-time camera feed - 📊 Monitor smoke detector status - 🔄 Check system uptime - 🎛️ Control alarm system - 📝 View event logs

⚠️ Troubleshooting

1. Camera not detected ```bash

   Check camera

   v4l2-ctl --list-devices ```

2. GPIO Permission Issues ```bash

   Add user to gpio group

   sudo usermod -a -G gpio $USER ```

3. Network Connectivity ```bash

   Test connections

   ping 192.168.1.10 ping 192.168.1.11 ```
