New type of speed cams?

[4vxc]

driving through W.Gosford today there was a checker plate box sitting on an angle in the medium strip of the Hwy facing traffic and what looked like lenses were visible. Heading further up the hill towards the F3 was another metal box attached to a pole with two black lines crossing the road just past it. A friend saw a sign saying something about 24hr camera's. Is this some new type of speed camera?
