Employee Pictures

To add employee pictures:

1. Create Image Directory:

   Create: static/img/ directory
   

2. Add Picture Files:

   Place images in: static/img/employee_name.jpg
   

3. Update Configuration:

   {
     "name": "John Doe",
     "mac_address": "aa-bb-cc-dd-ee-ff",
     "picture": "static/img/john_doe.jpg"
   }
   

How It Works

MAC Address Detection

The system uses the arp -a command to scan for devices on the local network. When an employee's device (identified by MAC address) is detected:

1. First Detection: Marked as "Time In"
2. Continuous Presence: Status remains "Present"
3. Temporary Absence: Marked as "On Break" if gone for short period
4. Extended Absence: Marked as "Time Out" if gone for extended period
5. 5:00 PM Timeout: Automatically marked as "Timed Out" at office closing

Status Logic

• Present: Device currently detected on network
• Absent: Device not detected and no previous activity today
• On Break: Device temporarily not detected but was present earlier
• Timed Out: Device not detected after 5:00 PM or extended absence

Data Storage

• SQLite Database: Stores all attendance events and employee data
• CSV Logs: Daily attendance summaries exported to logs/ directory
• JSON Files: Configuration and employee data in human-readable format

Security Features

Password Protection

• Admin Authentication: Required for adding new employees
• Password Hashing: Secure bcrypt hashing for stored passwords
• Default Password: 1122 (changeable through web interface)
• Session Security: No persistent login sessions for security

Data Privacy

• Local Storage: All data stored locally, no cloud transmission
• Offline Operation: No internet connection required
• Encrypted Passwords: Admin passwords securely hashed
• Access Control: Employee management requires authentication

Troubleshooting

Common Issues

"Permission Denied" Errors

• Windows: Run Command Prompt as Administrator
• Linux/macOS: Use sudo python main.py
• Alternative: Use non-admin mode (limited network scanning)

No Employees Detected

1. Verify MAC addresses in employees.json
2. Check if devices are connected to same network
3. Ensure WiFi is enabled on employee devices
4. Run python main.py --status to check configuration

Web Interface Not Loading

1. Check if port 5000 is available
2. Try different port: python main.py --port 8080
3. Verify firewall settings
4. Check console for error messages

Database Errors

1. Delete attendance.db to reset database
2. Restart application to recreate tables
3. Check file permissions in project directory

Network Scanning Limitations

Non-Admin Mode

When running without administrator privileges:

• Limited network scanning capabilities
• May not detect all devices
• Reduced accuracy in some network configurations
• Employee management features work normally

Admin Mode (Recommended)

• Full network scanning capabilities
• Accurate device detection
• Complete attendance tracking
• All features fully functional
