# Multi-Camera Simulation Guide
|
||||
|
||||
This guide explains how to simulate 4 cameras using a single webcam for testing the LPR integration in a realistic multi-camera environment.
|
||||
|
||||
## 🎯 Purpose
|
||||
|
||||
Simulate 4 real-world cameras to test:
|
||||
- Multiple camera streams with car detection
|
||||
- LPR integration across different cameras
|
||||
- Session management for multiple simultaneous detections
|
||||
- Database updates from different camera sources
|
||||
|
||||
## 🚀 Quick Start
|
||||
|
||||
### Windows
|
||||
```bash
|
||||
# Option 1: Use batch file (opens 4 terminal windows)
|
||||
start_4_cameras.bat
|
||||
|
||||
# Option 2: Manual start (run each in separate terminal)
|
||||
python multi_camera_simulator.py 1
|
||||
python multi_camera_simulator.py 2
|
||||
python multi_camera_simulator.py 3
|
||||
python multi_camera_simulator.py 4
|
||||
```
|
||||
|
||||
### Linux/macOS
|
||||
```bash
|
||||
# Option 1: Use shell script (opens 4 terminal windows)
|
||||
./start_4_cameras.sh
|
||||
|
||||
# Option 2: Manual start (run each in separate terminal)
|
||||
python3 multi_camera_simulator.py 1
|
||||
python3 multi_camera_simulator.py 2
|
||||
python3 multi_camera_simulator.py 3
|
||||
python3 multi_camera_simulator.py 4
|
||||
```
|
||||
|
||||
## 📡 Camera URLs
|
||||
|
||||
Each simulated camera will have unique URLs:
|
||||
|
||||
| Camera | HTTP Snapshot | RTSP Stream | Visual ID |
|
||||
|--------|--------------|-------------|-----------|
|
||||
| 1 | `http://10.101.1.4:8080/snapshot` | `rtsp://10.101.1.4:8550/stream` | Yellow border |
|
||||
| 2 | `http://10.101.1.4:8081/snapshot` | `rtsp://10.101.1.4:8551/stream` | Magenta border |
|
||||
| 3 | `http://10.101.1.4:8082/snapshot` | `rtsp://10.101.1.4:8552/stream` | Green border |
|
||||
| 4 | `http://10.101.1.4:8083/snapshot` | `rtsp://10.101.1.4:8553/stream` | Blue border |
|
||||
|
||||
## 🎨 Visual Differentiation
|
||||
|
||||
Each camera adds visual branding to help distinguish streams:
|
||||
|
||||
- **Camera 1**: Yellow border + "CAMERA 1" text
|
||||
- **Camera 2**: Magenta border + "CAMERA 2" text
|
||||
- **Camera 3**: Green border + "CAMERA 3" text
|
||||
- **Camera 4**: Blue border + "CAMERA 4" text
|
||||
- **All**: Timestamp with camera ID
|
||||
|
||||
## 🔧 Configuration Options

|
||||
|
||||
## 🏗️ CMS Configuration
|
||||
|
||||
Configure each camera in your CMS with these settings:
|
||||
|
||||
### Camera 1
|
||||
```
|
||||
Camera Identifier: webcam-camera-01
|
||||
Snapshot URL: http://10.101.1.4:8080/snapshot
|
||||
RTSP URL: rtsp://10.101.1.4:8550/stream
|
||||
Snapshot Interval: 2000

||||
```
|
||||

|
||||
```
|
||||
|
||||
## 🧪 Testing LPR Integration
|
||||
|
||||
With 4 cameras running, you can test:
|
||||
|
||||
1. **Multiple simultaneous detections** - Cars detected by different cameras
|
||||
2. **Session isolation** - Each camera gets separate session IDs
|
||||
3. **LPR processing** - License plate results for different cameras
|
||||
4. **Database updates** - Multiple car records with different session IDs
|
||||
|
||||
### Test Scenario
|
||||
1. Start all 4 cameras
|
||||
2. Connect all 4 to detector worker
|
||||
3. Show car to webcam (all cameras see it)
|
||||
4. Each camera should get separate session ID
|
||||
5. Send LPR results for each session ID
|
||||
6. Verify database updates for each camera
|
||||
|
||||
## 🔧 Troubleshooting
|
||||
|
||||
### Port Already in Use
|
||||
If you see port conflicts:
|
||||
```bash
|
||||
# Check what's using the port
|
||||
netstat -an | findstr :8080
|
||||
netstat -an | findstr :8550
|
||||
|
||||
# Use different base ports
|
||||
python multi_camera_simulator.py 1 --base-port 9080 --rtsp-base-port 9550
|
||||
```
|
||||
|
||||
### Webcam Access Issues
|
||||
```bash
|
||||
# Try different webcam indices
|
||||
python multi_camera_simulator.py 1 --webcam-index 1
|
||||
|
||||
# Check available cameras
|
||||
python -c "import cv2; print([i for i in range(10) if cv2.VideoCapture(i).isOpened()])"
|
||||
```
|
||||
|
||||
### FFmpeg Issues
|
||||
```bash
|
||||
# Disable RTSP if FFmpeg unavailable
|
||||
python multi_camera_simulator.py 1 --no-rtsp
|
||||
```
|
||||
|
||||
## 💡 Pro Tips
|
||||
|
||||
1. **Start cameras in order** (1, 2, 3, 4) for easier tracking
|
||||
2. **Use different terminals** for each camera to see individual logs
|
||||
3. **Check status endpoints** for health monitoring:
|
||||
- `http://10.101.1.4:8080/status`
|
||||
- `http://10.101.1.4:8081/status`
|
||||
- etc.
|
||||
4. **Monitor logs** to see which camera is processing which detection
|
||||
5. **Test LPR with unique session IDs** from each camera
|
||||
|
||||
This setup provides a realistic multi-camera environment for comprehensive LPR integration testing! 🎉
