Essex, Brentwood, A1023 Shenfield Road heading southbound (just after Middleton Hall Lane junction) there is a 30mph fixed speed camera.

However this camera pings “Speed camera ahead” warning regardless of your speed - I even had it go off when I was crawling in traffic at 5mph. My understanding of the many other cameras I encounter on my travels is that Waze only sounds “Speed camera ahead” if you are approaching(?) / exceeding the speed limit.
Map Editor shows this as a 30 mph camera, so I don’t expect it to ping if I’m approaching at, say, 5 mph. Am I correct in this understanding?
Thanks,
The speed shown on the icon is only a picture and nothing to do with the speed of the camera, WME uses the same icon for every speed camera.
If you select the camera the info panel (left hand side) shows this camera doesn’t have a speed set and is at default 0 mph so you will get a sound warning at all times.
I’m sure a local L3+ editor will be along shortly to correct this error 
Set to 30mph but it may take a few days before this updates on your sat nav.
