Are these new digital speed cameras? They're in some very unlikely
places if they are. I saw one in Rosalynn Hill, NW3 today. Going up!

SPECS cameras, I'd guess. They come in pairs, and are a known distance
apart. Those who make the journey between the two cameras at less than
the minimum time possible for compliance with the limit have their
details recorded digitally.
