Not a spy Camera

I had seen a number of these while walking around Amsterdam, I wasn’t sure what they were, they looked like cameras, but nothing like the cameras in London. I was sure they weren’t for “spying” on anyone. What were they?

I didn’t think i would find out……until…..

I was watching MegaWorld: Netherlands on Discovery Canada.

I enjoy construction shows, especially shows that feature places I have been.

During the segment about the subway in Amsterdam they talked about how important it was to make sure that none of the old buildings get damaged or shift when the new tunnels are dug.

What do they use, but these cool little “cameras” looking at mirrors placed on various buildings; making sure nothing has shifted or moved.

The system seems to be working. When I was there nothing seemed out of place….well…except for all the holes to dig the subway tunnels.
