How to run one scene in background continuously and pass some values to main scene

Hi i am new to unity but i know bit about C# and java coding, i am developing an application.
i want to know is it possible to run a scene in background , the scene running in background get some values from the hardware (Note : both scene are using same hardware ) and pass it to main scene
Eg: both scene get main and the running in background scene get streaming from camera simultanuously

A unity scene doesn’t really “run”, it just gets loaded or unloaded and when loaded objects and behaviours in it are processed each frame from the engine.

Sounds like what you’re looking for is a thread.

Thanks for your knowledge kindly will you please help me how to load a scene in background ?
