If it's a fixed speed camera, it can be added as a node, but if it's an average speed check, we need to know the start and end points. The cameras at the start of an average speed check aren't speed cameras as such; the entire section needs to be added as an enforcement relation.

I couldn't find any information about this installation online, so if you don't know the end point, I'm afraid we can't add anything here. Also, keep in mind that many average speed checks are indicated by signs before they're operational, as the signs already have an effect!
