Are all ours working?

In NZ they have many more camera boxes than cameras they place boxes on each side of school zones and just like a clearly marked police car they put drivers on their best behavior b/c you never know when it is that boxes turn.

My understanding is that, in the US and Canada, many cameras are owned by private companies which have contracts with state, province or local governments to operate these cameras. They get paid by a percentage of the fine governments collected. So, governments don't have to put up lots money to buy and install cameras to begin with.

So, my guess is, if you see a camera in the US or Canada, they probably are real, and very profitable as well. Because these companies have surveyed many locations to minimize the cost and maximize profit.

Of course, the traffic courts still have the final say on whether guilty or not on any given violation photo.

Looks like this one was not a dummy one.
