NDICam is the original NDI iPhone camera built by NDI broadcast infrastructure developers GallerySienna, mature and feature rich, now with both Full NDI and NDI HX2 modes.

The NDI (Network Device Interface) protocol connects to professional vision mixers and other devices, and delivers a high quality, low latency connection. NDICam is compatible with VMC, TC1, TriCaster, VMix, Wirecast and dozens of other professional IP video systems which support NDI.

- Simple to use - nothing to configure on your iOS device
- Switch between front and rear cameras during broadcast
- Auto Focus, AF Lock and Tap to Focus
- Auto Exposure, AE Lock and Tap to Expose
- Illumination light on/off
- Audio Mute Control
- Manual Naming of NDI Stream source
- 4 quality / performance levels to suit your device and network, plus NDI HX Option
- Pinch to zoom (where zoom is supported)
- Auto-lens mode for multi-lens cameras
- On screen live / preview tally plus optional use of camera flash as talent tally (with red gel cover).
- Option to prevent iOS device sleep
- Select 25FPS or 29.97FPS standard rate.
- Choice of Full NDI or NDI HX2 compression modes (HX2 at 2 to 20 mBit)

Front and Rear cameras can be selected at the touch of a button and NDICam features a 4 position quality vs frame rate slider to deliver optimum video suited to the quality of your wifi connection and your iPhone's processing performance. Depending on your iOS device, compression mode selected and Wifi network performance NDICam supports up to 1080 full HD resolution.

Control of flashlight, touch to focus, focus lock, pinch to zoom and audio enable are also included. You can even use the phone's torch as a Tally Light, by covering it with a red gel.

Note: Depending on the performance of your iOS device and your WIFI network, you may not see full frame rates when operating at maximum 1080 resolution with a full HD camera. Using HX2 mode will help if the bottleneck is your WIFI network.

Note: NDI is a high bandwidth protocol designed for local area Gigabit networks. In order to see good results you will need a fast, uncontested wifi connection. If you see slow frame rates, try improving the wifi environment, with a better router, less interference, directional antenna or maybe switch to 5GHz if you are on 2.4GHz. Use HX2 mode for lower bandwidth requirements.

NDICam is also compatible with wired ethernet connections to iOS devices which can help deliver smooth video compared to a poor quality Wifi network. Good results have been seen with lightning to ethernet adaptors.

You can now specify an NDI4 discovery server in the application settings. Note that you will need to restart the app for any changes to take effect. Specifying a discovery server will disable the standard mDNS (Bonjour) advertisement for the NDI Cam source, so your iOS device must be able to reach the discovery server one the network. If you experience problems - delete the Discovery Server entry and restart the app.

NB: NDI HX2 mode requires an NDI 4 compatible receiver.

Bad App+ Update

UPDATE: After getting in touch with Sienna (the company that makes this app) they quickly got in touch with Newtek and their app developer, and even CC me on the email! It turns out the “Newtek NDI Video monitor” is is not compatible with this app which runs NDI 1.x . They do have a newer version of the app that does work, and I was told they will try to schedule an update soon. 5 star customer service experience!

Begin original Review:
All NDI camera apps should be compatible with all other NDI apps because they use the same standard. This app works great with the Sienna monitor app, but fails to work with the Newtek NDI Video monitor app for Mac. Because it doesn’t work with the Newtek app, I’m not sure it would work with the Tricaster TC1 that I operate. I will update this review if anything changes and also try the other app by Newtek. But overall first impressions are not impressive.

Some confusion here

I just bought this app, installed on my iPhone XS Max, went through the step to use it with OBS but it didn’t work. In troubleshooting I deleted it to install again only to see 9.99 what I should see Get. I I’m now on my iPad what it installed with no issue.

I need to use thing on my iPhone. Fix this please

Developer Response ,

Hi YaGaYaW. NDICam works fine on iPhone XSMax. If you can't see the source, its mostly likely your networking configuration. Please follow the troubleshooting in the manual :

Works with OBS! (Only $10 instead of $20 for NewTek NDI Camera)

It's (currently) half the price of the app that everyone is telling OBS users to get if they want to use their iPhone as a webcam in OBS! The same plug-in works for this app as well.

Just a little heads up.

As for the actual app, I presume it is very similar to the other NDI app I mentioned. It is very network heavy and that can really increase the number of frames dropped. I did turn off the audio feed and the video improved quite a bit. If your 5GHz WiFi signal is strong on your computer and your phone, the video quality can be really good. I wouldn't say "crystal clear," but I was impressed, at least after I got the wifi sorted out.^^
