The other day I noticed a strange new grey box on a lamp-post in a village near where I live. Cunningly it was attached over the lamp-post's identification tag.
The following day, I noticed another on a rusty old signpost a little way down the road. What are these boxes for? The label, "DANGER High voltage", doesn't give anything away. I'd be surprised if an old signpost pole had a high voltage electricity supply, but the back of the box does appear to have a sealed gland connecting it to the post so I guess it's possible.
Any clues, please let me know.
Update:
According to the helpful folks in cam.misc (thanks!) these boxes are probably radar or microwave speed or proximity detectors. It looks like the council is conducting a survey of vehicle speed.
