How to get alerts about Speed Monitoring Cameras in GPS Maps Application?

I am using Here Maps (Here WeGO), but I do not get any warnings about speed monitoring cameras. I would also like to pay for such a service. The application well informs already if you drive too fast. I know there are some GPS devices which can give such alerts. I think TomTom, at least. Testing xavier_fakerat's proposal --- I see now interaction with CamerAlert but have not tested when driven. It took some time for the program to relocate to Baltics from London. But - Start here maps. Start then CamerAlert second time. The app crashes. It alerts all the time about unupdated maps although I just updated them. I will go with Sygic. OS: Android Oreo 8.0 Phone: OnePlus 3T Region: Sweden, Finland, Norway, Baltics Maps: Here We Go Maps, rarely Google Maps (because no easy offline use)
