If you are considering buying a speed camera detector we would suggest buying the best one you can afford, but for the most part they are reliant on the quality of the data they receive, so when considering various brands it is important to read the fine detail to determine which kinds of speed traps they can detect and how they receive information. It is also worth bearing in mind that navigation apps such as Waze and Google Maps can be configured to show speed camera alerts as well as your current speed and the speed limit on your current road.
