In a village near me there is a lamp-post in a 30 mph zone which has
a rectangular metal "tube" about 1 foot long by 6" square which is
pointing straight down at the road surface by the post. There is also
another device alongside, again pointing at the road. There are no
road markings like you get with speed cameras. I presume the larger
device is a camera and the smaller one is a light. The cameras are
angled so steeply that they could not see the number-plate of a car.
There is also a box on the lamp-post which may be some form of
control module.

Ignore the curvature of the lamp-post: it's distortion from the lens
in my dashcam: I had to wait until I was close to the lamp-post to
get the largest image, and that's when it's on the edge of the frame
where distortion is greatest.

Any ideas? I'm intrigued.

My guess would be a CCTV system that is not yet in use.

Why two separate devices tho ?* Surely yours don’t normally
have two and given they are different size, not very likely
to be one for each direction when in use unless they just
happen to have changed models and somewhere has to
have a mismatched pair.

The industrial estate where I used to have my factories had five
different cameras covering the entrance area - one B&W night camera and
one colour day camera facing in each direction plus a high definition
camera taking numberplates of vehicles entering (ANPR was not then
usual). They were not all of the same design.

And why point them at the ground
instead of just disabling them in the control unit ?

I assume that they are motorised and simply droop when not powered.
