Stavanger Airport now has live cameras!
From giving it a go, I can say that the live streaming is very fast.
The site also shows a live ATC map centred on Stavanger, taken from the excellent FlightRadar24 site. Below this, there’s an arrivals and departures board from the airport, showing what movements are due.
