iPhone Camera Connection Issues

If your iPhone camera isn’t appearing in pMix.studio’s source picker or won’t connect, work through these steps.

iPhone not appearing in discovery

Check the basics

  • Both the iPhone and iPad must be on the same Wi-Fi network
  • The pMix Camera app must be open and active on the iPhone (not in the background)
  • Make sure you’re on a 5 GHz or 6 GHz Wi-Fi band, not 2.4 GHz

Network requirements

pMix.studio uses Bonjour (mDNS) to discover iPhones on the network. Some networks block this:

  • Guest networks or client isolation — Many routers isolate devices on guest networks so they can’t see each other. Use the main network instead
  • Public/enterprise Wi-Fi — Networks in offices, hotels, and coffee shops often block device-to-device communication. Use a dedicated router
  • VPN — If either device has a VPN active, it may prevent local network discovery. Disable the VPN for production

Try refreshing

  • In pMix.studio, pull down on the source picker to refresh the discovery list
  • On the iPhone, close and reopen the pMix Camera app
  • Toggle Wi-Fi off and back on for both devices
  • If things still look weird, restart both the iPhone and the iPad as a quick sanity check. It sounds obvious, but it fixes a surprising amount of stubborn camera and discovery nonsense.

iPhone appears but won’t connect

Check the connection

  • The iPhone may be connected to a different subnet (e.g., 192.168.1.x vs 192.168.0.x)
  • Try pinging the iPhone’s IP address from another device to verify basic network connectivity

Firewall and permissions

  • On the iPhone, ensure the pMix Camera app has Local Network permission (Settings → Privacy & Security → Local Network)
  • On the iPad, ensure pMix.studio has Local Network permission

Restart the connection

  1. Remove the iPhone source from the slot on the iPad
  2. Close the pMix Camera app on the iPhone completely (swipe up from app switcher)
  3. Reopen the pMix Camera app
  4. Re-add the iPhone source on the iPad
  5. If it still refuses to behave, restart the iPhone and the iPad before digging deeper. As a sanity check, this is often worth doing early.

Connected but poor quality or high latency

Use 5 GHz or 6 GHz Wi-Fi

2.4 GHz Wi-Fi adds significant latency and is susceptible to interference. Always use 5 GHz or 6 GHz for live production.

Recommended Wi-Fi bands:

  • ✅ 6 GHz (Wi-Fi 6E) — Best performance, lowest latency, minimal interference (requires Wi-Fi 6E compatible devices)
  • ✅ 5 GHz — Excellent for production, widely supported
  • ❌ 2.4 GHz — Avoid for live production (high latency, congestion, interference)

Reduce network congestion

  • Other devices streaming video (Netflix, YouTube) on the same network consume bandwidth
  • A dedicated router for your production eliminates this problem

Check signal strength

  • Keep the iPhone within reasonable range of the Wi-Fi access point
  • Walls and obstacles reduce signal quality

Watch for the bad-Wi-Fi indicator

If the iPhone source shows a bad-Wi-Fi indicator, the app has detected that network conditions are hurting the stream — usually a mix of packet loss, rising round-trip time, or falling bitrate. Move the iPhone closer to the access point or switch bands.

Monitor health stats

Open the Health Stats panel in pMix.studio to check:

  • Packet loss — Should be under 0.1%. Higher values indicate network problems
  • Frame rate — Should match your expected rate (typically 30 fps)
  • Latency — Under 150 ms on LAN, 100–200 ms on remote networks

Auto-reconnection

If an iPhone camera disconnects (e.g., the iPhone goes to sleep, leaves Wi-Fi range, or the app is backgrounded), pMix.studio will automatically attempt to reconnect using exponential backoff. When the iPhone becomes available again, the connection is restored without manual intervention.

If auto-reconnection doesn’t work:

  1. Make sure the pMix Camera app is in the foreground on the iPhone
  2. Remove and re-add the source on the iPad
