Wireless trick

Regarding your article on the A9 speed camera project (18 June), apart from being a waste of £2 million, I think they are fake.

At the various sites where they are not yet installed, tubes for cables protrude from manholes, however there is no source of power at these rural sites or means of communicating from one camera to the next.

Unless the whole thing is done by radio I think we are being duped by a major confidence trick.
