1. Protocol Overview

   • WebSocket vs HTTP

   • Persistent connections

   • Bi-directional communication

   • Real-time updates

2. Key Features

   • Low latency

   • Binary support

   • Message framing

   • Connection management

💡 Pro Tip: Use heartbeat messages to maintain connection stability and detect disconnections early.

Connection Setup

Establishing Connection

1. Connection Code

   const ws = new WebSocket('wss://ws.airys.com/v1/stream');
   
   ws.onopen = () => {
     console.log('Connected to Airys WebSocket');
     ws.send(JSON.stringify({
       type: 'auth',
       token: 'your_api_token'
     }));
   };
   
   

2. Authentication

   • Token-based auth

   • Connection params

   • Secure handshake

   • Session management

Connection Management

1. Error Handling

   ws.onerror = (error) => {
     console.error('WebSocket error:', error);
     reconnect();
   };
   
   ws.onclose = (event) => {
     console.log('Connection closed:', event.code);
     if (event.code === 1006) {
       reconnect();
     }
   };
   
   

2. Reconnection Strategy

   • Automatic retry

   • Exponential backoff

   • Connection state

   • Health checks

Event Handling

Message Types

1. System Events

   {
     type: 'system',
     event: 'status',
     data: {
       status: 'online',
       timestamp: 1645678900
     }
   }
   
   

2. Camera Events

   • Stream start/stop

   • Quality changes

   • Error notifications

   • Status updates

Event Processing

1. Message Handling

   ws.onmessage = (event) => {
     const message = JSON.parse(event.data);
     switch (message.type) {
       case 'face_detected':
         handleFaceDetection(message.data);
         break;
       case 'stream_status':
         updateStreamStatus(message.data);
         break;
     }
   };
   
   

2. Event Subscription

   • Topic subscription

   • Event filtering

   • Priority handling

   • Queue management

Stream Management

Video Streaming

1. Stream Control

   // Start stream
   ws.send(JSON.stringify({
     type: 'stream_control',
     action: 'start',
     camera_id: 'cam_123'
   }));
   
   

2. Quality Control

   • Adaptive bitrate

   • Resolution control

   • Frame rate adjustment

   • Bandwidth management

Data Streaming

1. Real-time Data

   • Face detection events

   • Analytics data

   • Status updates

   • Performance metrics

2. Stream Processing

   • Data buffering

   • Frame processing

   • Event correlation

   • State management

Advanced Features

2. Message Optimization

   • Binary protocols

   • Message compression

   • Batch processing

   • Priority queues

Security Features

1. Secure Communication

   • TLS/SSL

   • Message encryption

   • Access control

2. Monitoring

   • Connection metrics

   • Performance stats

   • Error tracking

   • Usage analytics

Frequently Asked Questions

Q: How do I handle connection drops?

A: Implement automatic reconnection with exponential backoff. See Connection Management.

Q: What's the maximum message size?

A: Default limit is 1MB. For larger data, use chunking or dedicated file transfer endpoints.

Q: How many concurrent connections are supported?

A: Standard tier supports 100 concurrent connections. Enterprise accounts have customizable limits.
