cameras（cameras 视频）

Scope

This skill:

• ✅ Generates camera capture commands
• ✅ Guides integration with security systems
• ✅ Provides troubleshooting for camera issues

User-driven model:

• User provides camera credentials (RTSP URLs, passwords)
• User runs capture commands
• User installs required tools

This skill does NOT:

• ❌ Store camera credentials
• ❌ Run captures automatically without user request
• ❌ Access cameras without user-provided access info

Requirements

Required:

• ffmpeg — for capture and recording

Optional (user installs if needed):

• gphoto2 — for DSLR/mirrorless control
• v4l2-ctl — for USB cameras on Linux

Quick Reference

Core Rules

1. User Provides Camera Access

When user requests capture:

User: "Snapshot from my front door camera"
Agent: "I need the RTSP URL. Format: rtsp://user:pass@ip/stream
        Provide it or set CAMERA_FRONT_URL in env."
User: "rtsp://admin:pass@192.168.1.50/stream1"
→ Agent generates: ffmpeg -i "URL" -frames:v 1 snapshot.jpg

2. Common Commands

# Snapshot from RTSP (user provides URL)
ffmpeg -i "$RTSP_URL" -frames:v 1 snapshot.jpg

# Record 10s clip
ffmpeg -i "$RTSP_URL" -t 10 -c copy clip.mp4

# Webcam snapshot (macOS)
ffmpeg -f avfoundation -i "0" -frames:v 1 webcam.jpg

# Webcam snapshot (Linux)
ffmpeg -f v4l2 -i /dev/video0 -frames:v 1 webcam.jpg

3. Protocol Reference

4. Integration Patterns

With Home Assistant:

GET /api/camera_proxy/camera.front_door

User provides HA URL and token.

With Frigate:

• MQTT: frigate/events for alerts
• HTTP: /api/events/{id}/snapshot.jpg

5. Security

• Never log camera URLs with credentials
• Recommend user stores URLs in env vars
• RTSP streams may be unencrypted — warn about LAN security
