Belt and braces Welsh speed detection?

[MC Bodge]

On the westbound A55 this morning, at the average speed monitored zone near Rhuallt, I was surprised to see a speed(?) camera van with its rear windows open in the lay-by at the bottom of the hill. Nobody was appearing to be exceeding the limit.

Both seem more than a little pointless individually, but if it was a speed camera van, having both simultaneously appears ridiculous.

Well, at least it wasn't on another road.

They do this kind of thing for many reasons -

If its the downhill section they will be looking for people point and brake tailgaiting through the average speed section, people moving around not tracked by the fixed infrastructure get caught but most likely they are looking for non-speeding offences because the vans have cameras to look for you using you phone, not wearing seatbelts and stuff like that.

Seeing as there were two majorly disruptive RTCs in that area yesterday perhaps it shouldn't surprise us.

Which must have been caused by breaking the speed limit

Not necessarily. They don't just check for speed - read Craig's post above. Oh, and have a yourself.
