Hi, I'm not really sure because I have a shitty internet connection. Is the screen surveillance only a screenshot of the screen or it's a live continuous stream?

The Screen Surveillance sends at first a screenshot of the desktop, this could take a little bit with a slow internet connection. But then it sends only the changed parts of the next screenshot and so it looks like a stream. This should be fast enough, even for slow internet connections.

@MaxXor thanks. What protocol or technology are you using to produce it?

See this file: https://github.com/MaxXor/xRAT/blob/master/Client/Core/Helper/Helper.cs#L60
I use a technology to compare the last screenshot with the new one and then the method eliminates the pixels which are the same. In the end the client sends only the changed pixels to the server and the server overlays the changed pixels on the last screenshot. You should check out the code to fully understand it.
