variable speed cameras

[Jack960]

Hey all

I am a little bit concerned after driving down the highway today. Driving down the Western ring road, overhead variable speed signs displayed 40km so I slowed to 40. As usual there was some road works ahead (when isn't there on the western). Anyway at the end of the road works there was a truck that had a sign that said something along the lines of end of road works and all lanes opened up. I began accelerating, I was going about 80km when I drove under a sign which had cameras on it. About 100m further the overhead signs displayed 100km. Is there a chance I am going to get done for a 40km over ticket? Because regardless of what the temp signs say I imagine the camera's go off the variable speeds.
