Pick the right connection for your needs. Use USB for the most stable and lowest‑latency video. Use Wi‑Fi for quick, cable‑free calls on a strong 5GHz network.

Rule of thumb: If you’re streaming or presenting, choose USB. For casual calls near your router, Wi‑Fi on 5GHz is usually fine.

When to use USB vs Wi‑Fi

Choose USB if you need…
  • Lowest latency for streaming or gaming overlays
  • Stable image for long meetings and recordings
  • Lower risk of interference and dropped frames
Choose Wi‑Fi if you want…
  • Simple, cable‑free setup for quick calls
  • Freedom to position your phone as a camera
  • Good router proximity and a clean 5GHz channel

Optimize USB connection

  • Use a data‑capable USB cable; avoid charge‑only cables.
  • Prefer USB 3.x ports on your PC; try another port if detection fails.
  • Unlock your phone and trust the PC if prompted (especially on iOS).
  • Keep the phone powered; disable aggressive battery savers.
  • In apps, start with 1280×720 @30fps; increase to 1080p if stable.

Optimize Wi‑Fi connection

  • Use 5GHz near the router; avoid walls and interference.
  • Close heavy streaming/downloads on your network.
  • Reduce resolution to 720p if you see stutters or artifacts.
  • Position the phone with a clear line of sight to the router.
  • Restart your video app after starting Iriun on phone and PC.

Privacy & power tips

  • On Wi‑Fi, Iriun streams locally; use trusted networks.
  • For maximum privacy and lowest latency, use USB.
  • Keep your phone charged or connected to power for long sessions.

Connectivity troubleshooting

  • Not detected: Start Iriun on phone then PC; restart your video app. Try a different USB port or cable.
  • Black screen on Wi‑Fi: Move closer to the router, switch to 5GHz, or use USB.
  • Permissions: Windows → Settings → Privacy & security → Camera → Allow apps to access.
  • Still stuck? See Troubleshooting or perform a clean reinstall.
