user manual - functional summary




NDICam registers an NDI service on the Bonjour Network as soon as it launches. You can rename the NDI source name in the settings.


By default audio and video are sent, but you can turn off 'Enable Audio' to send video only.


The NDI On Off Slider in the main view allows you to freeze the NDI stream whilst you reposition the camera.


The lightening bolt icon allows control of the flashlight (where available).


The Camera switch icon allows real time switching between front and back cameras (where available).


Touch the image to set focus and exposure, hit the padlock icon to lock focus and exposure (where focus lock is available). Hit the lock again to turn off focus lock, or just tap the screen to re-focus.


The Quality vs Speed slider allows scaling of the image to suit device and network performance.


Pinch to Zoom in and Out (where available).


Prevent Sleep Mode can flatten your battery quickly.


Tally Flash links the  flash to receiver tally - cover with a red gel for a handy tally light.


If certain buttons are missing it is because the device does not support that mode.


NOTE:  When using NDICam 4.10 or later - which adds support for NDI4 and the NDI Discovery Service, make *certain* that your iOS device can reach the discovery server you have specified.  If you enter anything into the NDI4 Discovery Server field (and restart the NDI Cam app) - it will NO LONGER publish the NDI Cam stream using mDNS (Bonjour) - even if it cannot reach the discovery server.  If you experience problems, delete the entry in the discovery server field and completely restart the NDICam app.





Before doing anything else Turn off the firewall on your computer. Its nearly always to blame.  You can turn it back on and adjust settings once you get everything working.


Make certain the NDICam app is running and with the LIVE slider illuminated blue.


Restart the NDICam app by double clicking your phones home button and swiping the app up.  Then restart the NDICam app.


1) Please look at your wifi network in the iPhone settings and check the IP address.  Select the Settings app on your iPhone,  and click on Wifi (or Ethernet if you have a lightening to ethernet connection). Select the network connection and it will show you the IPv4 address.  This is the local IP address of the iPhone.


2) From a terminal or cmd prompt in your computer, you should be able to PING that address.  Open the TERMINAL app on macOS or cmd on Windows and enter :

'ping ' followed by the IP address of the iPhone.  Eg:   ping

Ping should respond with a series of replies.  If it can't reach the phone it will time out. If you cannot ping the phone  then there is a network issue.  There is no way anything is going to work if you can’t ping the iPhone - so take a closer look at your networking, r and contact your WIFI router vendor or computer supplier for assistance


3) if the PING works OK, it can be useful to use a bonjour browser app to check if it can see the NDI source being announced - this is how OBS finds the iPhone app.

Windows: https://hobbyistsoftware.com/bonjourbrowser

Mac:  https://apps.apple.com/us/app/discovery-dns-sd-browser/id1381004916?mt=12

You should see the iPhone as a type: _ndi._tcp.

If you dont see that - then the bonjour discovery isnt working, probably because your phone and computer are in different network subnet ranges.

In this case - provided the PING worked OK, you can force OBS to see the iPhone using NDI Access Manager

- Launch NDI Access Manager (from Newtek NDI tools for Windows or Mac)

- In the Remote Sources tab, create a new entry for an NDI Source and enter the IP address of the iPhone you found earlier.

Now you MUST restart the OBS app and any other NDI software to register the change, and have another try.

It also a good idea to try and see the iPhone app with NDI Monitor on Mac or NDI Studio Monitor on Windows.


Unless you know what you are doing, make sure the NDI4 Discovery Server field in the NDICam settings is EMPTY.  Restart the NDICam app by double clicking your phones home button and swiping the app up.  Then restart the NDICam app.


Thousands of people are using NDICam every day, and it *DOES* work.  If you are unable to see the iPhone as an NDI Source, or you see the source, but no video flows, there is a local issue on your system, it's not a problem with the NDICam app - so you will need to look closely at your networking, firewall and other connections and settings outside of the NDICam App.


OBS NDI Plug in Bug : A previous version of the NDI Plug in for OBS has a bug which can cause OBS to crash when adding an NDI Source. This has nothing to do with NDICam, and is a bug in the OBS NDI Plug in.  We understand this bug has now been fixed, and updating the NDI plug in for OBS to the latest version should resolve this issue.
