- **Purpose**: Test if the camera connection is working
- **SDK Function**: `CameraConnectTest()`
- **Use Case**: Diagnose connection issues
- **HTTP Method**: POST
- **Response**: `CameraTestResponse`
### 2. Reconnect (`/cameras/{camera_name}/reconnect`)
- **Purpose**: Soft reconnection to the camera
- **SDK Function**: `CameraReConnect()`
- **Use Case**: Most common fix for connection issues
- **HTTP Method**: POST
- **Response**: `CameraRecoveryResponse`
### 3. Restart Grab (`/cameras/{camera_name}/restart-grab`)
- **Purpose**: Restart the camera grab process
- **SDK Function**: `CameraRestartGrab()`
- **Use Case**: Fix issues with image capture
- **HTTP Method**: POST
- **Response**: `CameraRecoveryResponse`
### 4. Reset Timestamp (`/cameras/{camera_name}/reset-timestamp`)
- **Purpose**: Reset camera timestamp
- **SDK Function**: `CameraRstTimeStamp()`
- **Use Case**: Fix timing-related issues
- **HTTP Method**: POST
- **Response**: `CameraRecoveryResponse`
### 5. Full Reset (`/cameras/{camera_name}/full-reset`)
- **Purpose**: Complete camera reset (uninitialize and reinitialize)
- **SDK Functions**: `CameraUnInit()` + `CameraInit()`
- **Use Case**: Hard reset for persistent issues
- **HTTP Method**: POST
- **Response**: `CameraRecoveryResponse`
### 6. Reinitialize (`/cameras/{camera_name}/reinitialize`)
- **Purpose**: Reinitialize cameras that failed initial setup
- **SDK Functions**: Complete recorder recreation
- **Use Case**: Cameras that never initialized properly
- **HTTP Method**: POST
- **Response**: `CameraRecoveryResponse`
## Recommended Troubleshooting Workflow
When a camera has issues, follow this order:
1. **Test Connection** - Diagnose the problem
```http
POST http://localhost:8000/cameras/camera1/test-connection
```
2. **Try Reconnect** - Most common fix
```http
POST http://localhost:8000/cameras/camera1/reconnect
```
3. **Restart Grab** - If reconnect doesn't work
```http
POST http://localhost:8000/cameras/camera1/restart-grab
```
4. **Full Reset** - For persistent issues
```http
POST http://localhost:8000/cameras/camera1/full-reset
```
5. **Reinitialize** - For cameras that never worked
```http
POST http://localhost:8000/cameras/camera1/reinitialize
```
## Response Format
All recovery operations return structured responses:
### CameraTestResponse
```json
{
"success": true,
"message": "Camera camera1 connection test passed",
"camera_name": "camera1",
"timestamp": "2024-01-01T12:00:00"
}
```
### CameraRecoveryResponse
```json
{
"success": true,
"message": "Camera camera1 reconnected successfully",
"camera_name": "camera1",
"operation": "reconnect",
"timestamp": "2024-01-01T12:00:00"
}
```
## Implementation Details
### CameraRecorder Methods
- `test_connection()`: Tests camera connection
- `reconnect()`: Performs soft reconnection
- `restart_grab()`: Restarts grab process
- `reset_timestamp()`: Resets timestamp
- `full_reset()`: Complete reset with cleanup and reinitialization
### CameraManager Methods

- `reconnect_camera(camera_name)`: Reconnect specific camera
- `restart_camera_grab(camera_name)`: Restart grab for specific camera
- `reset_camera_timestamp(camera_name)`: Reset timestamp for specific camera
- `full_reset_camera(camera_name)`: Full reset for specific camera
- `reinitialize_failed_camera(camera_name)`: Reinitialize failed camera
### State Management
All recovery operations automatically update the camera status in the state manager:
- Success: Status set to "connected"
- Failure: Status set to appropriate error state with error message
## Error Handling
The system includes comprehensive error handling:
- SDK exceptions are caught and logged
- State manager is updated with error information
- Proper HTTP status codes are returned
- Detailed error messages are provided
## Testing
Use the provided test files:
- `api-tests.http`: Manual API testing with VS Code REST Client
- `test_camera_recovery_api.py`: Automated testing script
## Safety Features
- Recording is automatically stopped before recovery operations
- Camera resources are properly cleaned up
- Thread-safe operations with proper locking
- Graceful error handling prevents system crashes
## Common Use Cases
1. **Camera Lost Connection**: Use reconnect
2. **Camera Won't Capture**: Use restart-grab
3. **Camera Initialization Failed**: Use reinitialize
4. **Persistent Issues**: Use full-reset
5. **Timing Problems**: Use reset-timestamp
This recovery system provides robust tools to handle most camera-related issues without requiring system restart or manual intervention.

- ✅ Concurrent recording and streaming
- ✅ Error handling
### Manual Testing
1. Start the system: `python main.py`
2. Open `camera_preview.html` in browser
3. Start streaming for a camera
4. Trigger recording via MQTT or manual API
5. Verify both work simultaneously
## 🔄 Concurrent Operations
The system supports these concurrent operations:
| Operation | Recording | Streaming | Notes |
|-----------|-----------|-----------|-------|
| Recording Only | ✅ | ❌ | Normal operation |
| Streaming Only | ❌ | ✅ | Preview without recording |
| Both Concurrent | ✅ | ✅ | **Independent connections** |
### Example: Concurrent Usage
```bash
# Start streaming
curl -X POST http://localhost:8000/cameras/camera1/start-stream
# Start recording (while streaming continues)
curl -X POST http://localhost:8000/cameras/camera1/start-recording \
-H "Content-Type: application/json" \
-d '{"filename": "test_recording.avi"}'
# Both operations run independently!
```
## 🛠️ Configuration
### Stream Settings (in CameraStreamer)
```python
self.preview_fps = 10.0 # Lower FPS for preview
self.preview_quality = 70 # JPEG quality (1-100)
self._frame_queue.maxsize = 5 # Frame buffer size
```
### Camera Settings
The streamer uses the same camera configuration as recording:
- Exposure time from `camera_config.exposure_ms`
- Gain from `camera_config.gain`
- Optimized trigger mode for continuous streaming
## 🚨 Important Notes
### Camera Access Patterns
- **Recording**: Blocks camera during active recording
- **Streaming**: Uses separate connection, doesn't block
- **Health Checks**: Brief, non-blocking camera tests
- **Multiple Streams**: Multiple browsers can view same stream
### Performance Considerations
- Streaming uses additional CPU/memory resources
- Lower preview FPS reduces system load
- JPEG compression reduces bandwidth usage
- Frame queue prevents memory buildup
### Error Handling
- Automatic camera resource cleanup
- Graceful handling of camera disconnections
- Stream auto-restart capabilities
- Detailed error logging
## 🔍 Troubleshooting
### Stream Not Starting
1. Check camera availability: `GET /cameras`
2. Verify camera not in error state
3. Check system logs for camera initialization errors
4. Try camera reconnection: `POST /cameras/{name}/reconnect`
### Poor Stream Quality
1. Adjust `preview_quality` setting (higher = better quality)
2. Increase `preview_fps` for smoother video
3. Check network bandwidth
4. Verify camera exposure/gain settings
### Browser Issues
1. Try different browser (Chrome/Firefox recommended)
2. Check browser console for JavaScript errors
3. Verify CORS settings in API server
4. Clear browser cache and refresh
## 📈 Future Enhancements
Potential improvements for the streaming system:
- 🔄 WebRTC support for lower latency
