3.Download LM-Cam


Download the camera application "LM-Cam".

Only iPhone is supported.



4.Setting up OBS distribution


1.Start the camera application "LM-Cam" and start sending.


2.Start OBS, select "Scene", add "Source", and select "NDI Source".


3.Select the LM-Cam video from "Source name" in the NDI Source property.

If the signal is received successfully, the image will be displayed.


Set Latency mode to "Low" and press OK to display the image.

Please note that the LM-Cam image will not be displayed in the "Source name" unless you are in the same network environment.


In the case of LM-Cam, by setting [Video Encoding] to "HEVC", it is possible to send the same quality of video with up to about 1/10 of the transmission volume compared to Full NDI (100M), so it can be used comfortably even in environments with low network bandwidth.

LM-Cam: Menu → NDI → Video Encoding


If the video is choppy, it is recommended to use "HEVC" which has a lower transmission volume.

HEVC video is not displayed by Windows broadcast software: If HEVC video is not displayed correctly by Windows broadcast software, install "HEVC Video Extensions" to use it. This is not necessary for Mac.


Please note that the LM-Cam video will not be displayed in the "Source name" unless you are in the same network environment.


4.When the image is received from LM-Cam successfully, the image will be displayed.

Insert the image.


5.It is possible to connect multiple cameras in the same way.
