More new speed cameras!

Just noticed today 2 new speed cameras, both heading west on the A4, 1st one outside the Natural History Musuem on the corner of Cromwell Place, 2nd one just before the junction with Earls Court Road. Like the new one i spotted last week on Cheyne Walk, there are still no white lines painted on the road, so I’m assuming all 3 haven’t been activated yet. I’ve also spotted a sneaky, forward facing camera up in the trees on the south side of Shepherds Bush Green, again no white lines painted on the road.(thought cameras had to be clearly visible and not concealed?)

Anyone know of any others that have went up recently that i’ve missed?
