Hi,
Noticed last night a set of fairly small rear facing cameras with yellow marking on them just after the Blackwall Tunnel southbound exit, just before the 1st exit if memory serves me well, up high on the left hand side.I can only find this thread which is due an answer soon

Anybody know if they’re speed related and live, they look smaller than the average cameras put in for the barrier repairs
