NDI Camera: Easy Streaming

Review by eFreeware

Most camera apps treat the phone as the destination: you record to it, or you send a clip somewhere after the fact. NDI Camera does the opposite. It makes the phone itself a source, publishing live video and audio onto an NDI network so other software can pick it up. That single idea is what separates it from the general-purpose camera apps, and it is also the reason it will not appeal to everyone.

I think it is best suited to people who already have NDI somewhere in their setup: a live production, a studio, a classroom, a church service, a webinar, a conference stream. If your workflow already speaks NDI, adding a phone as an extra angle takes a button press rather than a new piece of hardware. If NDI means nothing to you yet, this app is a specialized tool rather than a general upgrade for your phone's camera.

Turning a phone into an NDI source

The core promise is straightforward: the phone becomes a professional live-streaming camera on your network, sending high-quality, low-latency video and audio. The developer lists MS Teams, Skype and Zoom among the destinations it can feed, which tells you the app is meant for both broadcast-style production and everyday video calls where a phone camera is better than a webcam.

There is one hard requirement to check before buying. The app needs support for NDI 4 or newer, so the receiving software or network has to be at that level. That is not a heavy ask for anyone already running NDI.

What appeals to me is the flexibility argument. Phones are everywhere, they have decent optics, and they are easy to move. Using one as an additional vantage point, or as a second angle in a presentation, is a much cheaper route than buying another camera and running more cable. The developer frames this as bringing new dimensions to broadcasts, webcasts and presentations, and that is a fair description of what the app is built for.

Control over how the picture is sent

The app does not just push whatever the sensor sees. You can choose between high, medium and low bandwidth modes, which matters when the network is shared or when several sources are running at once. Lower bandwidth trades quality for headroom; higher bandwidth gives you a better picture when the connection can take it. Having that choice in the app rather than in the receiving software is convenient.

On the framing side there is a grid overlay, autofocus and pinch-to-zoom, plus a switch between the front and rear cameras. An on-screen connection meter gives you a read on how the link is holding up, and a tally display shows preview and on-air status, which is the kind of feedback a presenter notices immediately when it is missing.

The tally light is the detail that tells you this was designed by people who work in live production. Knowing whether your feed is live or still in preview is basic information in a studio, and having it on the phone screen saves someone having to relay it over a radio. Version 1.7 added multiple tally modes and a modernized interface, along with a fix so the viewfinder shows the full video height.

The recent update also added a More menu in the bottom-right corner for streaming statistics, About information, PTZ control, and settings for a discovery server and sender monitoring. PTZ covers zoom, exposure and camera switching, with camera switching handled through preset recall, and the exposure slider is now continuous rather than stepped. For anyone running a multi-camera setup, that is a meaningful set of additions rather than cosmetic polish.

What the app costs

NDI Camera is a paid app at $19.99. There are no ads and no in-app purchases, so the price you see is the whole cost of the software. For a tool that slots into professional production work, that is a modest one-off figure.

It is worth comparing that price against the alternatives rather than judging it on its own. A dedicated hardware camera, or a capture device that turns a phone into a source, generally costs more than this, and a paid video-production application typically costs more as well. The trade-off is that the money buys a focused tool, not a broad editing or streaming suite.

The install base is small by consumer standards, over 10,000 installs, and the average rating sits at 3.3 from 926 ratings. That tells me this is a niche utility with a mixed reception rather than a mass-market app, which is consistent with the specialized job it does. The app was released in November 2020 and has been updated as recently as March 2026, so it is an actively maintained tool rather than a one-off experiment.

Alternatives worth weighing

If your goal is simply to make a phone camera look better in a video call, a general-purpose camera app or the built-in camera of your conferencing tool will usually be enough, and neither asks you to understand NDI. The advantage of NDI Camera appears when the phone has to become a proper source in a production, not just a nicer webcam.

The app concentrates on turning a phone into an NDI source for streaming setups. The app is built around sending a signal to something else, and its value depends on that something else existing.

If you are already committed to NDI, the comparison is less about other apps and more about other sources. A dedicated camera gives you better optics and mounting options; a phone gives you portability, a screen, and a price you have probably already paid. NDI Camera is the piece that lets the phone join the same workflow as the rest of your gear, which is a narrower but more useful role.

A focused tool for NDI workflows

I would recommend NDI Camera to people who run NDI-based productions and want an inexpensive, portable extra angle, and to presenters or teachers whose video calls would benefit from a phone camera feeding the same system as their other sources. The bandwidth modes, tally display, grid overlay and PTZ controls are the features that make it feel like production equipment rather than a novelty.

The conditions are clear. You need NDI 4 or newer, you need a destination to send to, and you need to be comfortable paying $19.99 up front with no ads or purchases involved. The 3.3 average rating suggests the experience has not pleased everyone, so it is worth checking that your setup matches the requirements before committing.

For the right user, the appeal is simple: the phone in your pocket becomes one more camera on the network, with the controls to make that feed usable. For everyone else, it is a specialist app doing a specialist job, and there is no harm in leaving it to the people who need exactly that.

What's new in version 1.83

Updated to support the 16KB page size requirement. Added a 'More' menu on the bottom-right to enable showing streaming statistics, open About info, enable PTZ control, and set discovery server and sender monitoring. PTZ control of zoom, exposure, and camera switching. Camera switching is done through preset recall. Exposure slider control is now continuous instead of stepped.
