I built an iOS app that turns an iPhone into an OMT camera source for vMix. As far as I can tell it's the first OMT camera app on the App Store, so I wanted to share it here in case it's useful.

It shows up automatically in the OMT source list — no IP config, just discovery on the LAN. It streams HD up to 4K, supports multi-lens zoom (0.5x / 1x / 2x), quality hot-switch while live, a tally indicator with torch feedback for the talent, and thermal management so it doesn't throttle during long sessions.

I'd be glad to hear what vMix users think, especially anyone currently using NDI camera apps — what works, what's missing, what you'd want from an OMT source. Happy to answer any technical questions about OMT vs NDI from the iOS side.

I've just published a short demo (1:15) showing OMTake in action with vMix:

OMTake — iPhone as a wireless OMT camera for vMix

It covers the full workflow: open the app, add an OMT source in vMix, and the iPhone shows up automatically on the network — no IP address to type. Also shows multi-lens zoom, the tally light with torch feedback, live quality switching, and how thermal management keeps the stream broadcast-safe on long sessions.

Since the last update, v1.3 also brought persistent settings and smoother stop/restart.

As always, feedback is very welcome — especially on what you'd like to see next. A few features already on the list: separate exposure/focus controls, configurable white balance, and orientation lock.
