Thanks Ip recorder you can turn on 2 kinect at same time.
Then, you need “somthing” between Notch and Iprecorder,
In my case I use Processing to get the image from the two kinects and send it to NOTCH like a SPOUT.
Thake in consideration NOTCH don´r support two SPOUT signal.
In my case was a dificult process that requires many test.
