New M1 camera's?

[ratboiler]

Left for work a little later than normal on the M1 heading from junction 13 (Bedford) to Luton sevices, I note that there are small camera's on grey posts every 50yds or so, they stop or are not yet erected just before the services. Any idea what sort they are?

They are hard shoulder monitoring camera's. So if a vehicle is is parked on the hard shoulder, they will not implement hard shoulder running.
