→‎Speed and Red Light Cameras: Returned accidentally removed text
Further note''Do not add an additional cameras in an attempt to produce the speed alert'', configurations that have as a second camera within approx. 400 metres will not generate an alert on the app. Therefore, intersections with both speed and red light camera configurations should be simplified to the above camera setup with excess cameras removed.
The resulting user experience is that the camera provides a consistent red-light warning. This convention will be revised if/when the app is changed to provide both warnings for a dual-function camera [ per forum discussion].
