Anyone know what the black slim rectangular cameras are on the lamp posts everywhere?

Does anyone know what these slim rectangular cameras are on the lamp posts popping up everywhere?

Googled it and cannot find a single image that looks like what i'm talking about.

Some are stating ANPR but then the images they use don't look like what i've seen.

Never got the chance to photograph one as i've always been driving.

Done a drive past in the locations i've seen them with google street view but the images must be old so they don't show.
