Hi Mike,
We’ve had issues at Humber on some of our Code Blue Stations. Most of the time, it’s an issue with the stability of the network connection especially when they are installed outdoors. I think the hardware of the Code Blue Station itself is robust, but the traffic on the network in which the station is connected to may cause some issue. The data cable of most of our Code Blue Stations are Cat6 and if the distance run is close to the limit of 90 meters, it could cause some connection issues.
I hope this helps.
