Bob Engelhardt explained :
The device should have cameras facing all directions, to catch the people
sneaking up on it with a baseball bat G.

Bob

In New South Wales Australia we have had speed cameras for many years
but recently "they" have been installing these multi function cameras
in place of what used to be simple Red Light cameras.

Most of the old speed cameras already have seperate picture cameras
mounted away and higher to catch vandals.

"They" are talking of introducing "avaerge speed" cameras on some
country roads to catch you if your journey time is too quick.
