Using marker to create location-like lens

So I have a poster, when you aim at the poster the lens starts

Behavior -> On Marker Found

Then I want to create a 3d scene where you can look around 360

-- 

When I add things to the scene, they don't stick to the markers orgin and are stuck to the camera / move with the camera. 

Is it possible to create a scene the camera is allowed to move around in?

example: you look at the poster and then fireworks start exploding all around you and you can spin around looking at the firework show going all around you
