Avg. speed cameras at A34 at Milton, Oxfordshire
Discussion
A colleague noticed something rather unusual about the bright yellow average speed cameras on the northbound approach to the Milton Park intersection of the A34 - they appear to have no power cables to the camera units. They have a wireless aerial sticking out, but that's it. Not to be confused with the blue traffic monitoring cameras which do appear to have power cables.
They look similar to those described on the "New Street Furniture" slide of this presentation by Vysionics:
http://www.20splentyforus.org.uk/Its_Time_For_20/P...
This describes "A new generation of columns/mounts" which are of "lightweight construction", "Smaller but distinctive" and "Passively safe". They have a "SPECS3 VECTOR fully integated module" with "No roadside cabinet"
In the SPECS3 VECTOR specification sheet on the Vysionics web site, it talks of 48VDC or 90-240VAC supplied via a column box providing 48V DC to the camera unit. 25W typical consumption. Different cameras shown have very distinctive black flexible conduit between the column and the camera.
The new generation 'Street furniture' cameras have a very lightweight and thin looking U bracket and no cable or apparent means of power delivery between the column and the camera.
(edit) There are wires from the gantry to the cameras, its just that they are much thinner than the type with the thick black flexible conduit. The 'Argos catalogue' school of marketing phtography obviously applies.
