Your iPhone as a two-camera rig
- Front and back cameras at once, live on the phone and in OBS Studio.
- Each camera is its own source:
<phone name> (iPhone Front)and<phone name> (iPhone Back). - Phone mic audio is optional and rides on the first camera feed.
- Local network only. Video goes straight from your phone to your own computer. Nothing goes to ServiceAi.

Quick answers
Do I need OBS Studio?
DualCam works with OBS Studio and with any other NDI® receiver on your network.
Does my video go to ServiceAi?
No. Video and audio go only over your local network to the receiver you connect. There is no ServiceAi server and no account.
Can I use 4K?
Yes, with one camera. Two cameras at once use 720p or 1080p.
Is the phone's microphone included?
Only if you turn it on. Phone mic audio rides on the first camera feed.
Where do my recordings go?
Files > On My iPhone > DualCam, or the iCloud Drive folder you picked in the app.
Is the computer control page safe?
It is off by default and has no password. Anyone on the same Wi-Fi can open it while it is on, so turn it on only on networks you trust.
