+# 🤖 AI Agent Video Integration Guide
+
+This guide provides comprehensive step-by-step instructions for AI agents and external systems to successfully integrate with the USDA Vision Camera System's video streaming functionality.
+
+## 🎯 Overview
+
+The USDA Vision Camera System provides a complete video streaming API that allows AI agents to:
+- Browse and select videos from multiple cameras
+- Stream videos with seeking capabilities
+- Generate thumbnails for preview
+- Access video metadata and technical information
+
+## 🔗 API Base Configuration
+
+### Connection Details
+```bash
+# Default API Base URL
+API_BASE_URL="http://localhost:8000"
+
+# For remote access, replace with actual server IP/hostname
+API_BASE_URL="http://192.168.1.100:8000"
+```
+
+### Authentication
+**⚠️ IMPORTANT: No authentication is currently required.**
+- All endpoints are publicly accessible
+- No API keys or tokens needed
+- CORS is enabled for web browser integration
+
+## 📋 Step-by-Step Integration Workflow
+
+### Step 1: Verify System Connectivity
+```bash
+# Test basic connectivity
+curl -f "${API_BASE_URL}/health" || echo "❌ System not accessible"
+
+# Check system status
+curl "${API_BASE_URL}/system/status"
+```
+
+**Expected Response:**
+```json
+{
+  "status": "healthy",
+  "timestamp": "2025-08-05T10:30:00Z"
+}
+```
+
+### Step 2: List Available Videos
+```bash
+# Get all videos with metadata
+curl "${API_BASE_URL}/videos/?include_metadata=true&limit=50"
+
+# Filter by specific camera
+curl "${API_BASE_URL}/videos/?camera_name=camera1&include_metadata=true"
+
+# Filter by date range
+curl "${API_BASE_URL}/videos/?start_date=2025-08-04T00:00:00&end_date=2025-08-05T23:59:59"
+```
+
+**Response Structure:**
+```json
+{
+  "videos": [
+    {
+      "file_id": "camera1_auto_blower_separator_20250804_143022.mp4",
+      "camera_name": "camera1",
+      "filename": "camera1_auto_blower_separator_20250804_143022.mp4",
+      "file_size_bytes": 31457280,
+      "format": "mp4",
+      "status": "completed",
+      "created_at": "2025-08-04T14:30:22",
+      "start_time": "2025-08-04T14:30:22",
+      "end_time": "2025-08-04T14:32:22",
+      "machine_trigger": "blower_separator",
+      "is_streamable": true,
+      "needs_conversion": false,
+      "metadata": {
+        "duration_seconds": 120.5,
+        "width": 1920,
+        "height": 1080,
+        "fps": 30.0,
+        "codec": "mp4v",
+        "bitrate": 5000000,
+        "aspect_ratio": 1.777
+      }
+    }
+  ],
+  "total_count": 1
+}
+```
+
+### Step 3: Select and Validate Video
+```bash
+# Get detailed video information
+FILE_ID="camera1_auto_blower_separator_20250804_143022.mp4"
+curl "${API_BASE_URL}/videos/${FILE_ID}"
+
+# Validate video is playable
+curl -X POST "${API_BASE_URL}/videos/${FILE_ID}/validate"
+
+# Get streaming technical details
+curl "${API_BASE_URL}/videos/${FILE_ID}/info"
+```
+
+### Step 4: Generate Video Thumbnail
+```bash
+# Generate thumbnail at 5 seconds, 320x240 resolution
+curl "${API_BASE_URL}/videos/${FILE_ID}/thumbnail?timestamp=5.0&width=320&height=240" \
+  --output "thumbnail_${FILE_ID}.jpg"
+
+# Generate multiple thumbnails for preview
+for timestamp in 1 30 60 90; do
+  curl "${API_BASE_URL}/videos/${FILE_ID}/thumbnail?timestamp=${timestamp}&width=160&height=120" \
+    --output "preview_${timestamp}s.jpg"
+done
+```
+
+### Step 5: Stream Video Content
+```bash
+# Stream entire video
+curl "${API_BASE_URL}/videos/${FILE_ID}/stream" --output "video.mp4"
+
+# Stream specific byte range (for seeking)
+curl -H "Range: bytes=0-1048575" \
+  "${API_BASE_URL}/videos/${FILE_ID}/stream" \
+  --output "video_chunk.mp4"
+
+# Test range request support
+curl -I -H "Range: bytes=0-1023" \
+  "${API_BASE_URL}/videos/${FILE_ID}/stream"
+```

+## 🚨 Error Handling
+
+### Common HTTP Status Codes
+```bash
+# Success responses
+200  # OK - Request successful
+206  # Partial Content - Range request successful
+
+# Client error responses  
+400  # Bad Request - Invalid parameters
+404  # Not Found - Video file doesn't exist
+416  # Range Not Satisfiable - Invalid range request
+
+# Server error responses
+500  # Internal Server Error - Failed to process video
+503  # Service Unavailable - Video module not available
+```
+
+### Error Response Format
+```json
+{
+  "detail": "Video camera1_recording_20250804_143022.avi not found"
+}
+```
+
+### Robust Error Handling Example
+```python
+def safe_video_operation(client, file_id):
+    try:
+        # Validate video first
+        if not client.validate_video(file_id):
+            return {"error": "Video is not valid or accessible"}
+        
+        # Get video info
+        video_info = client.get_video_info(file_id)
+        
+        # Check if streamable
+        if not video_info.get('is_streamable', False):
+            return {"error": "Video is not streamable"}
+        
+        return {"success": True, "video_info": video_info}
+        
+    except requests.exceptions.HTTPError as e:
+        if e.response.status_code == 404:
+            return {"error": "Video not found"}
+        elif e.response.status_code == 416:
+            return {"error": "Invalid range request"}
+        else:
+            return {"error": f"HTTP error: {e.response.status_code}"}
+    except requests.exceptions.ConnectionError:
+        return {"error": "Cannot connect to video server"}
+    except Exception as e:
+        return {"error": f"Unexpected error: {str(e)}"}
+```

+### Configuration Parameters
+- **`enable_caching`**: Enable/disable intelligent byte-range caching (default: True)
+- **`cache_size_mb`**: Maximum cache size in MB (default: 100)
+- **`cache_max_age_minutes`**: Cache entry expiration time (default: 30)

+- **`conversion_quality`**: Video conversion quality: "low", "medium", "high" (default: "medium")

+- **FFmpeg**: Optional, for video format conversion (graceful fallback if not available)
+- **Storage**: Sufficient disk space for video files and cache
+- **Memory**: Recommended 2GB+ RAM for caching and video processing
+
+## 🔐 Authentication & Security
+
+### Current Security Model
+**⚠️ IMPORTANT: No authentication is currently implemented.**
+
+- **Open Access**: All video streaming endpoints are publicly accessible
+- **CORS Policy**: Currently set to allow all origins (`allow_origins=["*"]`)
+- **Network Security**: Designed for internal network use only
+- **No API Keys**: No authentication tokens or API keys required
+- **No Rate Limiting**: No request rate limiting currently implemented
+
+### Security Considerations for Production
+
+#### For Internal Network Deployment
+```bash
+# Current configuration is suitable for:
+# - Internal corporate networks
+# - Isolated network segments
+# - Development and testing environments
+```
+
+#### For External Access (Recommendations)
+If you need to expose the video streaming API externally, consider implementing:
+
+1. **Authentication Layer**
+   ```python
+   # Example: Add JWT authentication
+   from fastapi import Depends, HTTPException
+   from fastapi.security import HTTPBearer
+
+   security = HTTPBearer()
+
+   async def verify_token(token: str = Depends(security)):
+       # Implement token verification logic
+       pass
+   ```
+
+2. **CORS Configuration**
+   ```python
+   # Restrict CORS to specific domains
+   app.add_middleware(
+       CORSMiddleware,
+       allow_origins=["https://yourdomain.com"],
+       allow_credentials=True,
+       allow_methods=["GET", "POST"],
+       allow_headers=["*"]
+   )
+   ```
+
+3. **Rate Limiting**
+   ```python
+   # Example: Add rate limiting
+   from slowapi import Limiter
+
+   limiter = Limiter(key_func=get_remote_address)
+
+   @app.get("/videos/")
+   @limiter.limit("10/minute")
+   async def list_videos():
+       pass
+   ```
+
+4. **Network Security**
+   - Use HTTPS/TLS for encrypted communication
+   - Implement firewall rules to restrict access
+   - Consider VPN access for remote users
+   - Use reverse proxy (nginx) for additional security
+
+### Access Control Summary
