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.

Dunno, all the motorised ones that I have looked at stay where the
last where when not powered. In other words the motor moves them
it doesn’t have to be powered to stay in a position. Stepper motor etc.
