Simple Video Chating with WebRTC

I do not know such a system. However, it was possible to switch between online traffic cameras and security cameras.

I’m running your source code on https://artunduzay.com/digitalinspection/index.
Is it possible to show two cameras at the same time as User and Enviroment and add “ull screen” feature?
In this case, the participant can view the camera he wants to watch in full screen.
The microphone will remain the default device.

If you can help me with this, I would be very happy.
I don’t want to take any more of your time.
Thanks in advance,
