Looking for specific streaming service.

Hello Guys! I looking for streaming service with ultra low delay(maximum 2 seconds, i'm living in Poland) and with possibility of creating private streams. Do u know service with that capabilities? I need these two capabilities to make stream from my work(I'm photographer/ cameraman /ovie maker). I need to make a stream from hospital where the doctors will make operation . Also, privacy (it has to hit only specific people who will get the link) and a delay of maximum 2 seconds is required (during the operation the doctors from the rest of the country will discuss about the procedure.) I have a lot of experience in making a film but I have never done such a thing before, so help me please!
