📹 StreamVision

StreamVision is a Node.js-based real-time DVR camera streaming platform that allows users to stream multiple RTSP camera feeds directly in the browser. It's now fully containerized with Docker, making deployment easier than ever. It supports dynamic DVR configurations, lazy loading of streams, and a responsive public viewer page.

🏗 System Architecture

The StreamVision architecture is designed for high-performance RTSP to HLS conversion with minimal latency, utilizing Node.js's scalability features.

1. Workflow Model: The application uses a Master-Worker process model (Node.js cluster module).
   • Master Process: Manages the lifecycle of workers and provides IPC (Inter-Process Communication) handlers to start/stop streams.
   • Worker Processes: Run the Express.js application, handling HTTP requests and serving the UI/API.
2. Ingestion: The system receives raw RTSP streams from DVRs or IP Cameras via TCP (configured in ffmpeg flags for reliability).
3. Processing: When a stream is requested, the Master process spawns a dedicated FFmpeg process. This process is managed by worker_threads and child_process.spawn.
4. Segmentation: FFmpeg converts the RTSP input into HLS (.m3u8) playlists and MPEG-TS (.ts) segments.
   • Segments are 1-second long for near real-time latency.
   • Stale segments are automatically cleaned up to save disk space.
5. Delivery: HLS segments are served via Express static middleware (or Nginx in production) and played back using Hls.js on the frontend.

🚀 Getting Started with Docker (Recommended)

Prerequisites

• Docker
• Docker Compose

1. Clone the Repository

git clone https://github.com/CodeByAmrit/StreamVision.git
cd StreamVision

2. Configure Environment

Create a .env file by copying the template file:

cp .env.example .env

Open .env and fill in your configuration:

Variable	Description	Example
PORT	Web server port	3000
DB_HOST	MySQL hostname	localhost
DB_USER	MySQL username	root
DB_PASSWORD	MySQL password	******
DB_DATABASE	MySQL database name	streamvision
jwt_token	Secret for auth tokens	secure_token_here
STREAM_AUTO_STOP_MINUTES	Auto-stop duration	120

---

🚀 API Documentation

The platform provides several internal and public API endpoints for stream management.

Public Endpoints (No Auth)

• GET /api/public/camera/:id/hls: Returns the active HLS URL for a specific camera.
• GET /public/dvr/:id: Direct link to the public viewing dashboard for a DVR.

Protected Endpoints (Auth Required)

• POST /api/start-stream: Starts an RTSP to HLS conversion session.
  • Body: { "rtspUrl": "rtsp://..." }
• POST /api/stop-stream: Manually terminates a stream session.
  • Body: { "rtspUrl": "rtsp://..." }

---

📊 Monitoring & Logging

StreamVision includes an integrated monitoring client for enterprise-grade observability.

• Metrics: Built-in Prometheus metrics exporter.
• Log Aggregation: Ready-to-use Grafana Loki integration for centralized log search.
• Audit Logs: Every camera/DVR state change is recorded with user attribution in utils/activityLogger.js.

---

📁 PDF Report Generation

Located in utils/reportGenerator.js, this utility allows for generating detailed PDF reports containing:

• Camera uptime and health status.
• System activity and security events.
• Customizable location-based summary statistics.

3. Database Setup

Ensure your MySQL server is running and accessible from the Docker container. Import the database structure using the provided SQL file:

# Example using MySQL CLI
mysql -u your_user -p your_database < database/structure.sql

4. Build and Run the Container

Use Docker Compose to build the image and start the container in the background.

docker-compose up --build -d

The application will now be running on the port you specified in your .env file (e.g., http://localhost:3000).

Managing the Container

• View logs: docker-compose logs -f
• Stop the container: docker-compose down

🔧 Troubleshooting & FAQ

RTSP Stream Not Loading?

• Ensure FFmpeg is installed and in your system PATH.
• Verify the RTSP URL is accessible from your server (try ffplay rtsp://your_url).
• Check Docker logs: docker-compose logs -f streamvision_app.
• Verify database camera configuration (RTSP URL, port, credentials).

HLS Performance Tuning

• Segments are 1-second long by default for low latency. If buffering occurs, adjust -hls_time in utils/streamStore.js.
• Adjust UV_THREADPOOL_SIZE in cluster.js if file I/O becomes a bottleneck.
