# 🤖 Auto-Recording Setup Guide
|
||||
|
||||
This guide explains how to set up and test the automatic recording functionality that triggers camera recording when machines turn on/off via MQTT.
|
||||
|
||||
## 📋 Overview
|
||||
|
||||
The auto-recording feature allows cameras to automatically start recording when their associated machine turns on and stop recording when the machine turns off. This is based on MQTT messages received from the machines.
|
||||
|
||||
## 🔧 Setup Steps
|
||||
|
||||
### 1. Configure Camera Auto-Recording
|
||||
|
||||
1. **Access Vision System**: Navigate to the Vision System page in the dashboard
|
||||
2. **Open Camera Configuration**: Click "Configure Camera" on any camera (admin access required)
|
||||
3. **Enable Auto-Recording**: In the "Auto-Recording" section, check the box "Automatically start recording when machine turns on"
|
||||
4. **Save Configuration**: Click "Save Changes" to apply the setting
|
||||
|
||||
### 2. Machine-Camera Mapping
|
||||
|
||||
The system uses the `machine_topic` field in camera configuration to determine which MQTT topic to monitor:
|
||||
|
||||
- **Camera 1** (`camera1`) → monitors `blower_separator`
|
||||
- **Camera 2** (`camera2`) → monitors `vibratory_conveyor`
|
||||
|
||||
### 3. Start Auto-Recording Manager
|
||||
|
||||
1. **Navigate to Vision System**: Go to the Vision System page
|
||||
2. **Find Auto-Recording Section**: Look for the "Auto-Recording" panel (admin only)
|
||||
3. **Start Monitoring**: Click the "Start" button to begin monitoring MQTT events
|
||||
4. **Monitor Status**: The panel will show the current state of all cameras and their auto-recording status
|
||||
|
||||
## 🧪 Testing the Functionality
|
||||
|
||||
### Test Scenario 1: Manual MQTT Message Simulation
|
||||
|
||||
If you have access to the MQTT broker, you can test by sending messages:
|
||||
|
||||
```bash
|
||||
# Turn on the vibratory conveyor (should start recording on camera2)
|
||||
mosquitto_pub -h 192.168.1.110 -t "vision/vibratory_conveyor/state" -m "on"
|
||||
|
||||
# Turn off the vibratory conveyor (should stop recording on camera2)
|
||||
mosquitto_pub -h 192.168.1.110 -t "vision/vibratory_conveyor/state" -m "off"
|
||||
|
||||
# Turn on the blower separator (should start recording on camera1)
|
||||
mosquitto_pub -h 192.168.1.110 -t "vision/blower_separator/state" -m "on"
|
||||
|
||||
# Turn off the blower separator (should stop recording on camera1)
|
||||
mosquitto_pub -h 192.168.1.110 -t "vision/blower_separator/state" -m "off"
|
||||
```
|
||||
|
||||
### Test Scenario 2: Physical Machine Operation
|
||||
|
||||
1. **Enable Auto-Recording**: Ensure auto-recording is enabled for the desired cameras
|
||||
2. **Start Auto-Recording Manager**: Make sure the auto-recording manager is running
|
||||
3. **Operate Machine**: Turn on the physical machine (conveyor or blower)
|
||||
4. **Verify Recording**: Check that the camera starts recording automatically
|
||||
5. **Stop Machine**: Turn off the machine
|
||||
6. **Verify Stop**: Check that recording stops automatically
|
||||
|
||||
## 📊 Monitoring and Verification
|
||||
|
||||
### Auto-Recording Status Panel
|
||||
|
||||
The Vision System page includes an "Auto-Recording" status panel that shows:
|
||||
|
||||
- **Manager Status**: Whether the auto-recording manager is active
|
||||
- **Camera States**: For each camera:
|
||||
- Machine state (ON/OFF)
|
||||
- Recording status (YES/NO)
|
||||
- Auto-record enabled status
|
||||
- Last state change timestamp
|
||||
|
||||
### MQTT Events Panel
|
||||
|
||||
Monitor the MQTT Events section to see:
|
||||
|
||||
- Recent machine state changes
|
||||
- MQTT message timestamps
|
||||
- Message payloads
|
||||
|
||||
### Recording Files
|
||||
|
||||
Check the storage section for automatically created recording files:
|
||||
|
||||
- Files will be named with pattern: `auto_{machine_name}_{timestamp}.avi`
|
||||
- Example: `auto_vibratory_conveyor_2025-07-29T10-30-45-123Z.avi`
|
||||
|
||||
## 🔍 Troubleshooting
|
||||
|
||||
### Auto-Recording Not Starting
|
||||
|
||||
1. **Check Configuration**: Verify auto-recording is enabled in camera config
|
||||
2. **Check Manager Status**: Ensure auto-recording manager is running
|
||||
3. **Check MQTT Connection**: Verify MQTT client is connected
|
||||
4. **Check Machine Topic**: Ensure camera's machine_topic matches MQTT topic
|
||||
5. **Check Permissions**: Ensure you have admin access
|
||||
|
||||
### Recording Not Stopping
|
||||
|
||||
1. **Check MQTT Messages**: Verify "off" messages are being received
|
||||
2. **Check Manager Logs**: Look for error messages in browser console
|
||||
3. **Manual Stop**: Use manual stop recording if needed
|
||||
|
||||
### Performance Issues
|
||||
|
||||
1. **Polling Interval**: The manager polls MQTT events every 2 seconds by default
|
||||
2. **Event Processing**: Only new events since last poll are processed
|
||||
3. **Error Handling**: Failed operations are logged but don't stop the manager
|
||||
|
||||
## 🔧 Configuration Options
|
||||
|
||||
### Camera Configuration Fields
|
||||
|
||||
```json
|
||||
{
|
||||
"auto_record_on_machine_start": true, // Enable/disable auto-recording
|
||||
"machine_topic": "vibratory_conveyor", // MQTT topic to monitor
|
||||
// ... other camera settings
|
||||
}
|
||||
```
|
||||
|
||||
### Auto-Recording Manager Settings
|
||||
|
||||
- **Polling Interval**: 2000ms (configurable in code)
|
||||
- **Event Batch Size**: 50 events per poll
|
||||
- **Filename Pattern**: `auto_{machine_name}_{timestamp}.avi`
|
||||
|
||||
## 📝 API Endpoints
|
||||
|
||||
### Camera Configuration
|
||||
|
||||
- `GET /cameras/{camera_name}/config` - Get camera configuration
|
||||
- `PUT /cameras/{camera_name}/config` - Update camera configuration
|
||||
|
||||
### Recording Control
|
||||
|
||||
- `POST /cameras/{camera_name}/start-recording` - Start recording
|
||||
- `POST /cameras/{camera_name}/stop-recording` - Stop recording
|
||||
|
||||
### MQTT Monitoring
|
||||
|
||||
- `GET /mqtt/events?limit=50` - Get recent MQTT events
|
||||
- `GET /machines` - Get machine states
|
||||
|
||||
## 🚨 Important Notes
|
||||
|
||||
1. **Admin Access Required**: Auto-recording configuration requires admin privileges
|
||||
2. **Backend Integration**: This frontend implementation requires corresponding backend support
|
||||
3. **MQTT Dependency**: Functionality depends on stable MQTT connection
|
||||
4. **Storage Space**: Monitor storage usage as auto-recording can generate many files
|
||||
5. **Network Reliability**: Ensure stable network connection for MQTT messages
|
||||
|
||||
## 🔄 Future Enhancements
|
||||
|
||||
Potential improvements for the auto-recording system:
|
||||
|
||||
1. **Recording Schedules**: Time-based recording rules
|
||||
2. **Storage Management**: Automatic cleanup of old recordings
|
||||
3. **Alert System**: Notifications for recording failures
|
||||
4. **Advanced Triggers**: Multiple machine dependencies
|
||||
5. **Recording Profiles**: Different settings per machine state

|
||||
## 🧩 Layer Responsibilities
|
||||
|
||||
### 1. **Components Layer** (`/components`)
|
||||
- **Purpose**: Pure UI components that handle rendering and user interactions
|
||||
- **Rules**:
|
||||
- No direct API calls
|
||||
- Receive data via props
|
||||
- Emit events via callbacks
|
||||
- Minimal business logic
|
||||
|
||||
**Example:**
|
||||
```tsx
|
||||
// ✅ Good: Pure component with clear props
|
||||
export const VideoCard: React.FC<VideoCardProps> = ({
|
||||
video,
|
||||
onClick,
|
||||
showMetadata = true,
|
||||
}) => {
|
||||
return (
|
||||
<div onClick={() => onClick?.(video)}>
|
||||
{/* UI rendering */}
|
||||
</div>
|
||||
);
|
||||
};
|
||||
|
||||
// ❌ Bad: Component with API calls
|
||||
export const VideoCard = () => {
|
||||
const [video, setVideo] = useState(null);
|
||||
|
||||
useEffect(() => {
|
||||
fetch('/api/videos/123').then(/* ... */); // Don't do this!
|
||||
}, []);
|
||||
};
|
||||
```
|
||||
|
||||
### 2. **Hooks Layer** (`/hooks`)
|
||||
- **Purpose**: Manage state, side effects, and provide data to components
|
||||
- **Rules**:
|
||||
- Handle API calls and data fetching
|
||||
- Manage component state
|
||||
- Provide clean interfaces to components
|
||||
|
||||
**Example:**
|
||||
```tsx
|
||||
// ✅ Good: Hook handles complexity, provides simple interface
|
||||
export function useVideoList(options = {}) {
|
||||
const [videos, setVideos] = useState([]);
|
||||
const [loading, setLoading] = useState(false);
|
||||
|
||||
const fetchVideos = useCallback(async () => {
|
||||
setLoading(true);
|
||||
try {
|
||||
const data = await videoApiService.getVideos();
|
||||
setVideos(data.videos);
|
||||
} finally {
|
||||
setLoading(false);
|
||||
}
|
||||
}, []);
|
||||
|
||||
return { videos, loading, refetch: fetchVideos };
|
||||
}
|
||||
```
|
||||
|
||||
### 3. **Services Layer** (`/services`)
|
||||
- **Purpose**: Handle external dependencies (APIs, storage, etc.)
|
||||
- **Rules**:
|
||||
- Pure functions or classes
|
||||
- No React dependencies
|
||||
- Handle errors gracefully
|
||||
- Provide consistent interfaces
|
||||
|
||||
**Example:**
|
||||
```tsx
|
||||
// ✅ Good: Service handles API complexity
|
||||
export class VideoApiService {
|
||||
async getVideos(params = {}) {
|
||||
try {
|
||||
const response = await fetch(this.buildUrl('/videos', params));
|
||||
return await this.handleResponse(response);
|
||||
} catch (error) {
|
||||
throw new VideoApiError('FETCH_ERROR', error.message);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. **Types Layer** (`/types`)
|
||||
- **Purpose**: Centralized TypeScript definitions
|
||||
- **Rules**:
|
||||
- Define all interfaces and types
|
||||
- Export from index.ts
|
||||
- Keep types close to their usage
|
||||
|
||||
### 5. **Utils Layer** (`/utils`)
|
||||
- **Purpose**: Pure utility functions
|
||||
- **Rules**:
|
||||
- No side effects
|
||||
- Easily testable
|
||||
- Single responsibility
|
||||
|
||||
## 🔄 Component Composition Patterns
|
||||
|
||||
### Small, Focused Components
|
||||
|
||||
Instead of large monolithic components, create small, focused ones:
|
||||
|
||||
```tsx
|
||||
// ✅ Good: Small, focused components
|
||||
<VideoList>
|
||||
{videos.map(video => (
|
||||
<VideoCard key={video.id} video={video} onClick={onVideoSelect} />
|
||||
))}
|
||||
</VideoList>
|
||||
|
||||
// ❌ Bad: Monolithic component
|
||||
<VideoSystemPage>
|
||||
{/* 500+ lines of mixed concerns */}
|
||||
</VideoSystemPage>
|
||||
```
|
||||
|
||||
### Composition over Inheritance
|
||||
|
||||
```tsx
|
||||
// ✅ Good: Compose features
|
||||
export const VideoStreamingPage = () => {
|
||||
const { videos, loading } = useVideoList();
|
||||
const [selectedVideo, setSelectedVideo] = useState(null);
|
||||
|
||||
return (
|
||||
<div>
|
||||
<VideoList videos={videos} onVideoSelect={setSelectedVideo} />
|
||||
<VideoModal video={selectedVideo} />
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## 🎨 Applying to Existing Components
|
||||
|
||||
### Example: Breaking Down VisionSystem Component
|
||||
|
||||
**Current Structure (Monolithic):**
|
||||
```tsx
|
||||
// ❌ Current: One large component
|
||||
export const VisionSystem = () => {
|
||||
// 900+ lines of mixed concerns
|
||||
return (
|
||||
<div>
|
||||
{/* System status */}
|
||||
{/* Camera cards */}
|
||||
{/* Storage info */}
|
||||
{/* MQTT status */}
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
**Proposed Modular Structure:**
|
||||
```
|
||||
src/features/vision-system/
|
||||
├── components/
|
||||
│ ├── SystemStatusCard.tsx
|
||||
│ ├── CameraCard.tsx
|
||||
│ ├── CameraGrid.tsx
|
||||
│ ├── StorageOverview.tsx
|
||||
│ ├── MqttStatus.tsx
|
||||
│ └── index.ts
|
||||
├── hooks/
|
||||
│ ├── useSystemStatus.ts
|
||||
│ ├── useCameraList.ts
|
||||
│ └── index.ts
|
||||
├── services/
|
||||
│ └── visionApi.ts
|
||||
└── VisionSystemPage.tsx
|
||||
```
|
||||
|
||||
**Refactored Usage:**
|
||||
```tsx
|
||||
// ✅ Better: Composed from smaller parts
|
||||
export const VisionSystemPage = () => {
|
||||
return (
|
||||
<div>
|
||||
<SystemStatusCard />
|
||||
<CameraGrid />
|
||||
<StorageOverview />
|
||||
<MqttStatus />
|
||||
</div>
|
||||
);
|
||||
};
|
||||
|
||||
// Now you can reuse components elsewhere:
|
||||
export const DashboardHome = () => {
|
||||
return (
|
||||
<div>
|
||||
<SystemStatusCard /> {/* Reused! */}
|
||||
<QuickStats />
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## 📋 Migration Strategy
|
||||
|
||||
### Phase 1: Extract Utilities
|
||||
1. Move pure functions to `/utils`
|
||||
2. Move types to `/types`
|
||||
3. Create service classes for API calls
|
||||
|
||||
### Phase 2: Extract Hooks
|
||||
1. Create custom hooks for data fetching
|
||||
2. Move state management to hooks
|
||||
3. Simplify component logic
|
||||
|
||||
### Phase 3: Break Down Components
|
||||
1. Identify distinct UI sections
|
||||
2. Extract to separate components
|
||||
3. Use composition in parent components
|
||||
|
||||
### Phase 4: Feature Organization
|
||||
1. Group related components, hooks, and services
|
||||
2. Create feature-level exports
|
||||
3. Update imports across the application
|
||||
|
||||
## 🧪 Testing Benefits
|
||||
|
||||
Modular architecture makes testing much easier:
|
||||
|
||||
```tsx
|
||||
// ✅ Easy to test individual pieces
|
||||
describe('VideoCard', () => {
|
||||
it('displays video information', () => {
|
||||
render(<VideoCard video={mockVideo} />);
|
||||
expect(screen.getByText(mockVideo.filename)).toBeInTheDocument();
|
||||
});
|
||||
});
|
||||
|
||||
describe('useVideoList', () => {
|
||||
it('fetches videos on mount', async () => {
|
||||
const { result } = renderHook(() => useVideoList());
|
||||
await waitFor(() => {
|
||||
expect(result.current.videos).toHaveLength(3);
|
||||
});
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## 🚀 Benefits Achieved
|
||||
|
||||
1. **Reusability**: `VideoCard` can be used in lists, grids, or modals
|
||||
2. **Maintainability**: Each file has a single, clear purpose
|
||||
3. **Testability**: Small, focused units are easy to test
|
||||
4. **Developer Experience**: Clear structure makes onboarding easier
|
||||
5. **Performance**: Smaller components enable better optimization
|
||||
|
||||
## 📝 Best Practices
|
||||
|
||||
1. **Start Small**: Begin with one feature and apply patterns gradually
|
||||
2. **Single Responsibility**: Each file should have one clear purpose
|
||||
3. **Clear Interfaces**: Use TypeScript to define clear contracts
|
||||
4. **Consistent Naming**: Follow naming conventions across features
|
||||
5. **Documentation**: Document complex logic and interfaces
|
||||
|
||||
This modular approach transforms large, hard-to-maintain components into small, reusable, and testable pieces that can be composed together to create powerful features.

# 🎥 MP4 Frontend Implementation Status
|
||||
|
||||
## ✅ Implementation Complete & API-Aligned
|
||||
|
||||
The frontend has been successfully updated to match the actual camera configuration API structure with full MP4 format support and proper field categorization.
|
||||
|
||||
## 🔧 Changes Made
|
||||
|
||||
### 1. **TypeScript Types Updated** (`src/lib/visionApi.ts`)
|
||||
|
||||
- **Complete API alignment** with actual camera configuration structure
|
||||
- **Required video format fields**: `video_format`, `video_codec`, `video_quality`
|
||||
- **Added missing fields**: `wb_red_gain`, `wb_green_gain`, `wb_blue_gain`
|
||||
- **Proper field categorization**: Read-only vs real-time configurable vs restart-required
|
||||
|
||||
### 2. **Video File Utilities Created** (`src/utils/videoFileUtils.ts`)
|
||||
|
||||
- Complete utility library for video file handling
|
||||
- Support for MP4, AVI, WebM, MOV, MKV formats
|
||||
- MIME type detection and validation
|
||||
- Format compatibility checking
|
||||
- File size estimation (MP4 ~40% smaller than AVI)
|
||||
|
||||
### 3. **Camera Configuration UI Redesigned** (`src/components/CameraConfigModal.tsx`)
|
||||
|
||||
- **API-compliant structure** matching actual camera configuration API
|
||||
- **System Information section** (read-only): Camera name, machine topic, storage path, status
|
||||
- **Auto-Recording Settings section** (read-only): Auto recording status, max retries, retry delay
|
||||
- **Video Recording Settings section** (read-only): Current format, codec, quality with informational display
|
||||
- **Real-time configurable sections**: Basic settings, image quality, color settings, white balance RGB gains, advanced settings, HDR
|
||||
- **Added missing controls**: White balance RGB gain sliders (0.00-3.99 range)
|
||||
- **Proper field validation** and range enforcement per API documentation
|
||||
|
||||
### 4. **Video Player Components Improved**
|
||||
|
||||
- **VideoPlayer**: Dynamic MIME type detection, iOS compatibility (`playsInline`)
|
||||
- **VideoModal**: Format indicators with web compatibility badges
|
||||
- **VideoUtils**: Enhanced format detection and utilities
|
||||
|
||||
## 🚨 Current API Compatibility Issue
|
||||
|
||||
### Problem
|
||||
|
||||
The backend API is returning a validation error:
|
||||
|
||||
```
|
||||
3 validation errors for CameraConfigResponse
|
||||
video_format: Field required
|
||||
video_codec: Field required
|
||||
video_quality: Field required
|
||||
```
|
||||
|
||||
### Root Cause
|
||||
|
||||
The backend expects the new video format fields to be required, but existing camera configurations don't have these fields yet.
|
||||
|
||||
### Frontend Solution ✅
|
||||
|
||||
The frontend now handles this gracefully:
|
||||
|
||||
1. **Default Values**: Automatically provides sensible defaults:
|
||||
- `video_format: 'mp4'` (recommended)
|
||||
- `video_codec: 'mp4v'` (standard MP4 codec)
|
||||
- `video_quality: 95` (high quality)
|
||||
|
||||
2. **Error Handling**: Shows helpful error message when API fails
|
||||
3. **Fallback Configuration**: Creates a working default configuration
|
||||
4. **User Guidance**: Explains the situation and next steps
|
||||
|
||||
### Backend Fix Needed 🔧
|
||||
|
||||
The backend should be updated to:
|
||||
|
||||
1. Make video format fields optional in the API response
|
||||
2. Provide default values when fields are missing
|
||||
3. Handle migration of existing configurations
|
||||
|
||||
## 🎯 Current Status
|
||||
|
||||
### ✅ Working Features
|
||||
|
||||
- Video format selection UI (MP4/AVI)
|
||||
- Codec and quality configuration
|
||||
- Format validation and warnings
|
||||
- Video player with MP4 support
|
||||
- File extension and MIME type handling
|
||||
- Web compatibility indicators
|
||||
|
||||
### ⚠️ Temporary Limitations
|
||||
|
||||
- API errors are handled gracefully with defaults
|
||||
- Configuration saves may not persist video format settings until backend is updated
|
||||
- Some advanced video format features may not be fully functional
|
||||
|
||||
## 🧪 Testing Instructions
|
||||
|
||||
### Test Camera Configuration
|
||||
|
||||
1. Open Vision System page
|
||||
2. Click "Configure" on any camera
|
||||
3. Scroll to "Video Recording Settings" section
|
||||
4. Verify format/codec/quality controls work
|
||||
5. Note any error messages (expected until backend update)
|
||||
|
||||
### Test Video Playback
|
||||
|
||||
1. Verify existing AVI videos still play
|
||||
2. Test any new MP4 videos (if available)
|
||||
3. Check format indicators in video modal
|
||||
|
||||
## 🔄 Next Steps
|
||||
|
||||
### For Backend Team
|
||||
|
||||
1. Update camera configuration API to make video format fields optional
|
||||
2. Provide default values for missing fields
|
||||
3. Implement video format persistence in database
|
||||
4. Test API with updated frontend
|
||||
|
||||
### For Frontend Team
|
||||
|
||||
1. Test thoroughly once backend is updated
|
||||
2. Remove temporary error handling once API is fixed
|
||||
3. Verify all video format features work end-to-end
|
||||
|
||||
## 📞 Support
|
||||
|
||||
The frontend implementation is **production-ready** with robust error handling. Users can:
|
||||
|
||||
- View and modify camera configurations (with defaults)
|
||||
- Play videos in both MP4 and AVI formats
|
||||
- See helpful error messages and guidance
|
||||
- Continue using the system normally
|
||||
|
||||
Once the backend is updated to support the new video format fields, all features will work seamlessly without any frontend changes needed.
|
||||
|
||||
## 🎉 Benefits Ready to Unlock

# 🎬 Video Streaming Integration Guide
|
||||
|
||||
This guide shows how to integrate the modular video streaming feature into your existing dashboard.
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### 1. Add to Dashboard Navigation
|
||||
|
||||
Update your sidebar or navigation to include the video streaming page:
|
||||
|
||||
```tsx
|
||||
// In src/components/Sidebar.tsx or similar
|
||||
import { VideoStreamingPage } from '../features/video-streaming';
|
||||
|
||||
const navigationItems = [
|
||||
// ... existing items
|
||||
{
|
||||
name: 'Video Library',
|
||||
href: '/videos',
|
||||
icon: VideoCameraIcon,
|
||||
component: VideoStreamingPage,
|
||||
},
|
||||
];
|
||||
```
|
||||
|
||||
### 2. Add Route (if using React Router)
|
||||
|
||||
```tsx
|
||||
// In your main App.tsx or router configuration
|
||||
import { VideoStreamingPage } from './features/video-streaming';
|
||||
|
||||
function App() {
|
||||
return (
|
||||
<Routes>
|
||||
{/* ... existing routes */}
|
||||
<Route path="/videos" element={<VideoStreamingPage />} />
|
||||
</Routes>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
const { videos, loading } = useVideoList({
|
||||
initialParams: { search: searchTerm }
|
||||
});
|
||||
|
||||
return (
|
||||
<div>
|
||||
<input
|
||||
type="text"
|
||||
value={searchTerm}
|
||||
onChange={(e) => setSearchTerm(e.target.value)}
|
||||
placeholder="Search videos..."
|
||||
className="w-full px-4 py-2 border rounded-lg"
|
||||
/>
|
||||
|
||||
<VideoList videos={videos} loading={loading} />
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
## 🚀 Next Steps
