iPhone Cameras

pMix can use iPhones as wireless camera sources over your local Wi-Fi network. The iPhone runs the pMix camera companion app, and the iPad discovers and connects to it automatically.

Setup

  1. Install the pMix Camera app on your iPhone
  2. Ensure both the iPhone and iPad are on the same Wi-Fi network (5 GHz recommended)
  3. Open the pMix Camera app on the iPhone
  4. On the iPad, tap + on an empty slot and choose iPhone Cam
  5. Select your iPhone from the discovered devices list

The connection is established automatically. You’ll see the iPhone’s camera feed appear in the source slot within a few seconds.

How it works

The iPhone captures video using its hardware encoder and streams it to the iPad using WebRTC peer-to-peer transport. This provides:

  • Low latency — Typically 100–200 ms end-to-end
  • Hardware encoding — H.264 via the iPhone’s VideoToolbox encoder
  • Encrypted transport — DTLS-SRTP encryption is always on
  • Audio included — The iPhone’s microphone audio is captured and delivered alongside video

Multi-camera sync

When using multiple iPhones, pMix automatically synchronizes the feeds. The app measures the network delay to each camera and adjusts timing so all feeds present at the same moment — no manual configuration needed.

Remote camera control

Once connected, you can control the iPhone camera directly from the iPad:

  • Zoom — Pinch or use the zoom slider
  • Focus — Tap to focus, or enable manual focus
  • Exposure — Adjust exposure compensation
  • White balance — Auto or manual temperature/tint
  • Torch — Toggle the flashlight
  • Camera switch — Toggle front/back camera
  • Ultra-wide — Switch to the ultra-wide lens (if available)

See Camera Control / PTZ for more details.

Screen sharing

The iPhone can also share its screen instead of the camera feed:

  1. In the pMix Camera app, switch to Screen mode
  2. Start the iOS screen broadcast
  3. The iPad receives the iPhone’s screen content with audio

This works in the background — you can use other apps on the iPhone while sharing.

Network recommendations

  • Use 5 GHz Wi-Fi — 2.4 GHz has too much latency and interference for reliable video
  • A dedicated router or access point for your production is ideal
  • Keep the iPhone within reasonable range of the Wi-Fi access point
  • For multi-camera setups, a Wi-Fi 6 router handles the bandwidth demands better
