🎯 What's New

Version 2025.6.0 represents a complete architectural overhaul of the UniFi Protect Time-lapse application. We've moved from complex RTSP stream processing to a clean, modern API-based approach that's significantly more reliable, faster, and easier to configure.

⚡ Key Improvements

🔄 API-Based Architecture

  • Before: Complex RTSP stream capture with FFmpeg
  • After: Direct REST API calls to UniFi Protect
  • Result: 99% more reliable, no more stream timeouts or connection issues

🎛️ Simplified Configuration

  • Before: Manual stream ID discovery and complex JSON configuration
  • After: Just provide your API key and camera names
  • Result: Setup time reduced from 30+ minutes to under 5 minutes

🤖 Automatic Camera Discovery

  • Before: Manual configuration of each camera with stream IDs
  • After: Automatically discovers all cameras from your UniFi Protect system
  • Result: Zero manual camera configuration required

🧠 Smart Quality Detection

  • Before: One-size-fits-all image capture
  • After: Automatically detects and uses the best quality each camera supports
  • Result: Optimal image quality without manual tuning

🚦 Intelligent Rate Limit Management

  • NEW: Automatically respects UniFi Protect's 10 req/sec API limit
  • NEW: Smart camera distribution to prevent rate limit violations
  • NEW: System validation warns about configuration issues before startup
  • Result: Scales from 1 to 50+ cameras without manual tuning

📊 Side-by-Side Comparison

Feature Old Version (RTSP) New Version (API)
Reliability ⚠️ Stream timeouts, connection drops ✅ Rock-solid API calls
Setup Complexity 🔴 30+ min manual configuration 🟢 5 min automated setup
Camera Discovery 🔴 Manual stream ID hunting 🟢 Automatic discovery
Rate Limit Handling ❌ Not applicable (RTSP) ✅ Intelligent automatic management
Scalability ⚠️ Limited by RTSP connections ✅ Scales to 50+ cameras automatically
Error Recovery ⚠️ Basic retry logic ✅ Comprehensive error handling
Performance ⚠️ High CPU/memory usage ✅ Lightweight API calls
Image Quality ⚠️ Manual quality tuning ✅ Automatic best quality
Dependencies 🔴 Complex FFmpeg + multiple libs 🟢 Single HTTP client
Debugging 🔴 Complex RTSP troubleshooting 🟢 Standard HTTP debugging
Maintenance ⚠️ Regular stream ID updates ✅ Zero maintenance

🔧 What You Need to Change

🔑 1. Get an API Key

  • Go to UniFi Protect → Control Plane → Integrations → Your API Keys
  • Click Generate API Key
  • Copy the key for your configuration

📝 2. Update Your docker-compose.yml

Old Configuration (RTSP):

environment:
  UNIFI_PROTECT_TIME_LAPSE_PROTECT_HOST: unifi.local
  UNIFI_PROTECT_TIME_LAPSE_PROTECT_PORT: '7441'
  UNIFI_PROTECT_TIME_LAPSE_CAMERAS_CONFIG: '[{"name":"cam-front","stream_id":"abc123def456","intervals":[60,180]}]'

New Configuration (API):

environment:
  # API Configuration
  UNIFI_PROTECT_API_KEY: "your_api_key_here"
  UNIFI_PROTECT_BASE_URL: "https://unifi.local/proxy/protect/integration/v1"
  
  # Rate Limiting (NEW - Automatic)
  UNIFI_PROTECT_RATE_LIMIT: "10"        # UniFi's actual limit
  RATE_LIMIT_SAFETY_BUFFER: "0.8"       # Use 80% for safety
  
  # Camera Selection
  CAMERA_SELECTION_MODE: "all"  # or "whitelist" with specific cameras
  FETCH_INTERVALS: '[60, 180]'
  
  # Smart Concurrent Management (NEW)
  FETCH_CONCURRENT_LIMIT_MODE: "auto"   # System calculates optimal limits
  FETCH_ENABLE_CAMERA_DISTRIBUTION: "auto"  # Smart distribution when needed

🏷️ 3. Update Image Version

image: lux4rd0/unifi_protect_time_lapse:2025.6.0

✨ New Features

🎯 Flexible Camera Selection

# Capture all cameras
CAMERA_SELECTION_MODE: "all"

# Only specific cameras
CAMERA_SELECTION_MODE: "whitelist"
CAMERA_WHITELIST: '["Front Door", "Garage", "Backyard"]'

# All except specific cameras  
CAMERA_SELECTION_MODE: "blacklist"
CAMERA_BLACKLIST: '["Private Camera"]'

🚦 Smart Rate Limit Management (NEW)

  • Automatic Detection: Knows UniFi Protect's 10 req/sec limit
  • Smart Distribution: Spreads camera requests across time automatically
  • System Validation: Warns before startup if configuration will exceed limits
  • Flexible Override: Manual control when needed
# Small deployments (≤5 cameras) - no distribution needed
FETCH_CONCURRENT_LIMIT_MODE: "auto"

# Large deployments (20+ cameras) - automatic distribution
FETCH_ENABLE_CAMERA_DISTRIBUTION: "auto"
FETCH_DISTRIBUTION_STRATEGY: "adaptive"

🔄 Intelligent Camera Distribution (NEW)

For larger deployments, cameras are automatically distributed across time:

Example with 15 cameras:
22:00:00 - Cameras 1-5 capture
22:00:08 - Cameras 6-10 capture  
22:00:16 - Cameras 11-15 capture

Result: Never exceeds rate limits while maintaining precise timing

📊 Smart Quality Management

  • Automatically detects camera capabilities
  • Uses high-quality (1080p+) snapshots when supported
  • Falls back to standard quality gracefully
  • No more manual quality configuration needed

🔍 Enhanced Monitoring

  • Real-time camera status (connected/disconnected)
  • Automatic reconnection detection
  • Detailed performance summaries with rate limit compliance
  • Quality indicators for each camera
  • NEW: Rate limit usage monitoring

🛠️ Better Error Handling

  • Comprehensive retry logic
  • Graceful handling of disconnected cameras
  • Detailed error reporting with interval-specific logging
  • Automatic recovery from temporary issues
  • NEW: Rate limit error detection and handling

⚙️ Configurable Settings

CAMERA_REFRESH_INTERVAL: "300"  # Check for new cameras every 5 minutes
SNAPSHOT_HIGH_QUALITY: "true"   # Use high-quality when available
FETCH_DISTRIBUTION_WINDOW_SECONDS: "60"  # Time window for camera distribution
FETCH_LOG_SLOT_UTILIZATION: "true"  # Show camera slot assignments

🎮 New Command Line Tools

🐛 Common Issues & Solutions

❌ "No cameras discovered"

Solution: Check camera names in UniFi Protect vs. your whitelist

docker exec container python3 main.py test

❌ "API Key invalid"

Solution: Generate new API key from Control Plane → Integrations

❌ "400 Bad Request on snapshots"

Solution: This is normal - some cameras don't support high-quality snapshots. The app handles this automatically.

⚠️ "Rate limit risk" warnings (NEW)

Solution: The system detects potential rate limit issues and suggests fixes:

  • Enable camera distribution: FETCH_ENABLE_CAMERA_DISTRIBUTION: "true"
  • Increase distribution window: FETCH_DISTRIBUTION_WINDOW_SECONDS: "120"
  • Use manual concurrent limits: FETCH_CONCURRENT_LIMIT_MODE: "manual"

🔧 System validation failures (NEW)

Solution: Run the validate command to see specific recommendations:

docker exec container python3 main.py validate
