Frigate NVR Configuration Expert

Comprehensive Frigate NVR configuration assistance with optimized YAML generation, detector setup, and troubleshooting.

BEFORE YOU START

This skill prevents 12+ common errors and saves ~60% tokens on Frigate configuration.

Known Issues This Skill Prevents

1. Bus errors from insufficient shared memory allocation
2. Green/distorted video from incorrect resolution configuration
3. Database locked errors when using network storage for SQLite
4. Missing audio in recordings due to default audio stripping
5. MQTT connection failures from using localhost in Docker
6. Coral TPU not detected due to missing device passthrough
7. High CPU usage from missing hardware acceleration
8. False positives from missing motion masks on timestamps
9. No alerts triggered due to misconfigured required_zones
10. Recording corruption from h265 streams without transcoding
11. go2rtc WebRTC failures from missing STUN configuration
12. Object detection misses from wrong detect stream resolution

Quick Start

Step 1: Create Minimal Configuration

mqtt:
  enabled: false

cameras:
  front_door:
    ffmpeg:
      inputs:
        - path: rtsp://user:pass@192.168.1.100:554/stream1
          roles:
            - detect
    detect:
      width: 1280
      height: 720
      fps: 5

Why this matters: Start with the absolute minimum to verify camera connectivity before adding complexity. Frigate requires explicit detect stream role assignment.

Step 2: Add Hardware-Accelerated Detector

detectors:
  coral:
    type: edgetpu
    device: usb

# OR for Intel with OpenVINO:
detectors:
  ov:
    type: openvino
    device: GPU

Why this matters: CPU detection is not recommended for production. Even a single USB Coral TPU dramatically reduces CPU usage and improves detection latency.

Step 3: Enable Recording with Retention

record:
  enabled: true
  retain:
    days: 1
    mode: motion
  alerts:
    retain:
      days: 14
  detections:
    retain:
      days: 7

cameras:
  front_door:
    ffmpeg:
      inputs:
        - path: rtsp://user:pass@192.168.1.100:554/stream1
          roles:
            - detect
        - path: rtsp://user:pass@192.168.1.100:554/stream2
          roles:
            - record

Why this matters: Use separate streams for detect (low-res) and record (high-res) to optimize performance. Retention modes prevent storage from filling up.

Critical Rules

Always Do

• Use width and height that match your camera's ACTUAL resolution (verify with VLC)
• Set detect fps between 5-10 (higher wastes resources, lower misses events)
• Use separate streams for detect (sub-stream) and record (main stream)
• Allocate adequate shm-size in Docker (64MB minimum per camera)
• Create motion masks for timestamp overlays and areas with constant motion
• Use environment variables for credentials: {FRIGATE_RTSP_PASSWORD}
• Test RTSP URLs in VLC first before adding to Frigate config

Never Do

• Never use localhost or 127.0.0.1 for MQTT inside Docker containers
• Never set detect resolution higher than 1280x720 (wastes detector capacity)
• Never enable recording without specifying retention policy
• Never mount /media/frigate on network storage without relocating database
• Never mix multiple detector types for object detection (e.g., Coral + OpenVINO)
• Never use UDP RTSP transport without explicit configuration (TCP is default)

Common Mistakes

Wrong:

cameras:
  cam1:
    ffmpeg:
      inputs:
        - path: rtsp://192.168.1.100/stream
          roles:
            - detect
            - record
    detect:
      width: 1920
      height: 1080
      fps: 30

Correct:

cameras:
  cam1:
    ffmpeg:
      inputs:
        - path: rtsp://192.168.1.100/substream
          roles:
            - detect
        - path: rtsp://192.168.1.100/mainstream
          roles:
            - record
    detect:
      width: 1280
      height: 720
      fps: 5

Why: Using 1080p@30fps for detection wastes resources. Detection works best at 720p or lower at 5fps. Always use the camera's sub-stream for detection and main stream for recording.

Key settings:

• detect.fps: 5 is optimal for most cameras (reduces detector load)
• detect.width/height: Must match actual camera sub-stream resolution
• record.retain.mode: Use motion or active_objects to save storage
• motion.mask: Define polygons as comma-separated coordinates
• zones.coordinates: Bottom-center of bounding box determines zone presence

Troubleshooting

Camera Shows Offline

Symptoms: Camera fps shows 0, web UI shows offline status

Solution:

# Test RTSP URL directly
ffprobe -rtsp_transport tcp "rtsp://user:pass@ip:554/stream"

# Check Docker logs
docker logs frigate 2>&1 | grep -i "camera_name"

High CPU Usage

Symptoms: CPU consistently above 80%, system becomes unresponsive

Solution:

1. Enable hardware acceleration (see presets above)
2. Reduce detect fps from 10 to 5
3. Lower detect resolution to 720p or below
4. Add Coral TPU for object detection

No Objects Detected

Symptoms: Motion detected but no object events created

Solution:

1. Verify detector is configured and running: check /api/stats
2. Check object filters aren't too restrictive (min_area, threshold)
3. Ensure detect stream resolution is correct
4. Verify objects list includes desired types

Recording Not Working

Symptoms: Events show but no recordings available

Solution:

# Ensure record role is assigned
cameras:
  cam1:
    ffmpeg:
      inputs:
        - path: rtsp://camera/stream
          roles:
            - record  # Must be explicitly set
    record:
      enabled: true  # Must be true

Setup Checklist

Before deploying Frigate, verify:

• Docker and docker-compose installed
• RTSP URLs tested in VLC (note actual resolution)
• Camera credentials ready for environment variables
• Storage volume has adequate space (100GB+ recommended)
• Shared memory size configured (64MB per camera minimum)
• Hardware acceleration device mapped (if applicable)
• Coral TPU device mapped (if using)
• MQTT broker accessible (if integrating with Home Assistant)
• Port 8971 available for web UI
• Firewall allows required ports (8554, 8555 for streaming)
