Didn't notice. Both were like the old one at The Spa Hotel - rectangular boxes with a camera slot on top of a square pole. Pointed at equidistant lines about 30 metres ahead.
On a related issue, I noticed a new speed detection van parked at a Very sly place inbound on the M!/N1 just after the Coolock junction. As you go up the hill from the tunnel entrance, the speed limit reduces to 60 Km/hour and behind the next wall on the drivers left hand side was the white van on revenue collection duty. It is stunts like this that gives speed detection a bad name. And no, I was under the speed limit at the time. You have been warned.
