A few things worth knowing
The stream repeats so missed frames can be recovered. There is no return channel: stop the sender once the receiver finishes. Color mode and Turbo need good lighting and camera hardware. Files are not encrypted in the visual stream; anyone who can see the code may scan it. Camera access requires HTTPS or localhost.
