## Usage

### Starting the Application

#### Web Interface Mode (Default)
```bash
python main.py
```
Access the web interface at: http://localhost:5000

#### Console Mode
```bash
python main.py --console
```

#### Custom Port
```bash
python main.py --port 8080
```

#### System Status
```bash
python main.py --status
```

### Web Interface Features

#### Dashboard Overview
- **System Status**: Current monitoring state and employee count
- **Statistics Cards**: Real-time counts of present, absent, on break, and timed out employees
- **Employee Status**: Live employee cards with status badges and time information
- **Recent Events**: Timeline of latest attendance events

#### Employee Management
1. **Adding Employees**:
   - Click "Add Employee" button
   - Fill in employee name and MAC address
   - Optionally add picture path
   - Enter admin password (default: 1122)
   - Click "Add Employee"

2. **Searching Employees**:
   - Use the search box to find employees by name or MAC address
   - Results update in real-time

3. **Changing Admin Password**:
   - Click "Settings" button
   - Enter current password and new password
   - Click "Change Password"

#### Monitoring Controls
- **Start Monitoring**: Begin attendance tracking
- **Stop Monitoring**: Pause attendance tracking
- **Refresh Data**: Manually update all data
- **Export CSV**: Download daily attendance summary

### 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**:
   ```json
   {
     "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
