Private road 'speed camera'

[rockford22]

Today I ended up down a road which subsequently became marked as private (painted in white lettering on the road). This road leads to a large multi national refinery and is a dead end it a mile or so further down.

Driving to find a suitable place to turn I passed what looked like a private speed camera. A quarter the size of a gatso, rectangular, painted yellow and with a single large lens facing against direction of travel. At the base was a waterproof box secured with a padlock. It had no wording or logos on it. The road was marked with the usual 30mph signs and even had a little safety camera sign below it.

Is there any way this can be used as enforceable evidence?

Why would the council erect safety camera warning signs on a private road?

Thanks for replies - I had thought it could perhaps be used for internal discipline but had not seen in practice. The road itself is well sighted and straight with just fields either side....I am curious how it could be worth company investment to police a speed limit.

Perhaps ANPR anti fly tiping makes more sense given the remote location but camera looked unlike anything I have seen in the UK before.

(For any doubters I was in a 1.4 Polo seeking a national trust car park with a car full of dogs, not out to find the next top road )
