is there any way of controling a handheld camera in notch? with an iphone? like unreal engine, you can use your iphone to get a handheld shot very easy. is there anything like this to implement hardware camera in notch? i cannot afford the ncam package. is there a future plan to implement a more cheap avaiable normal camera or motion sensor ? 
You can use Zigsim pro to get position and rotation data to Notch via OSC.
With TouchDesigner and a Vive tracker for about $99

Use an exposable camera and load the notch block in TouchDesigner…In Touch map the CH of the Vive to a Camera Component then Drag that to the camera of the Notch Block…
In fact you could even use the Iphone to control the cam in Touch…
