Boxes on light poles - freeway and forrest highway
Posted: Fri Jun 24, 2016 10:35 pm
Hi.
Just wondering if anyone knows what the small white boxes are on the freeway and Forrest Highway light poles are.
The boxes are maybe 5m agl and about 120x120x120mm.
The tilt of the box seems to be important. I cant see any lens or window on them.
They seem to be around intersections so my guess is a movement sensor of some kind.
Anyone know?
Over.
Chhhhhhhhht
