Hey.

• On iOS, this is very likely not supported due to iOS' constraints. Per <Camera> component we use a single AVCaptureSession, and you can only have one of those active at the same time I think. If you want to stream data from multiple Cameras on iOS you would need to create an AVMultiCamCaptureSession or whatever it is called, which has an entirely different API and isn't easy to add to VisionCamera at all.
• On Android, this might be supported. Depends on the HAL implementation (aka your phone), so might work on some Samsungs, might not work on some Huaweis - I don't know.

In short; just try it, and see what happens. If it doesn't work, it doesn't work.

We could build this feature specifically for your app through my consulting agency, but that is very likely really complex.
