Claude 7dc9a762a0 frigate.sh: interactive camera wizard generates go2rtc + cameras config
Previously Frigate always wrote a placeholder config.yml the operator had
to hand-edit to add cameras. Now install_frigate prompts to add cameras
one at a time (name, RTSP IP/port/user/password/path, optional sub-stream,
enabled, notifications), matching the go2rtc + cameras structure used in
production frigate configs:

- Each camera gets a go2rtc stream entry (+ optional _sub for detection)
  and a cameras: block with ffmpeg inputs/roles, detect, notifications
- RTSP credentials/IPs are written to .env as FRIGATE_* variables (first
  camera gets FRIGATE_RTSP_USER/PASSWORD, later cameras get numbered
  suffixes _1, _2, ... to avoid collisions) and referenced in config.yml
  via Frigate's {FRIGATE_VAR} substitution syntax — secrets never appear
  in the YAML directly
- docker-compose.yml now includes env_file: .env so those vars actually
  reach the container for substitution to work
- Skipping all camera prompts falls back to the original starter
  config.yml for manual editing, preserving existing behavior
- README and DRY-RUN summary updated to reflect the new flow

# Frigate NVR
AI-powered network video recorder with real-time object detection for
security cameras. Detects people, cars, animals, and more.
- Web UI: http://localhost:5000
- RTSP restream: port 8554
- WebRTC: port 8555
- Recordings: \`$FRIGATE_MEDIA\`
- Config: \`config/config.yml\` — cameras configured during install ($CAM_INDEX added)
- Credentials: \`.env\` — RTSP user/pass/IP per camera as FRIGATE_* variables
## Manage
\`\`\`bash
cd $FRIGATE_DIR
docker compose up -d # start
docker compose down # stop
docker compose logs -f # logs
docker compose pull && docker compose up -d # update
\`\`\`
## Adding/editing cameras later
Re-run the installer (\`sudo ./setup.sh frigate\`) to add more cameras through
the same wizard, or edit \`config/config.yml\` and \`.env\` by hand — camera
credentials in config.yml use Frigate's \`{FRIGATE_VAR}\` substitution syntax,
resolved from \`.env\` at container startup.
## First steps
1. Review \`config/config.yml\` — adjust detection zones, masks, retention
2. Start Frigate: \`docker compose up -d\`
3. Open http://localhost:5000 to view cameras and configure detection zones
## Hardware acceleration
- Intel/AMD GPU: uncomment the \`devices: [/dev/dri/renderD128]\` block
- Google Coral TPU: set \`detectors.default.type: edgetpu\` + add USB device
- Docs: https://docs.frigate.video/configuration/hardware_acceleration
