We have those aswell since 2016 or 2017 I think, they’re stationary at roads that usually have a huge amount of almost non moving traffic.Since there was a slight increase in chatter with photo radar, I thought I’d add this.
This is the Mesta Fusion that’s being used in Edmonton Alberta Canada. It made it’s introduction here February 2018 (Thanks @Dukes ) but it’s something to keep in mind.
It is K band, but uses 6 quick changing K band frequencies. It changes so fast, that all the detectors on the market.... as of today, can not detect it properly... or at all.
It’s primarily used for RLC and “Speed on Green” ( speeding through the intersection) here.
It also has the capabilities to have the guts removed and moved to another enclosure so you’ll never know with 100% certainty if it’s active or not.
As you can see from the video... it is capable of much more.
