There is an alternative to Coyotte which will, alas, become paying if you haven't already.
Trapster is a free software that allows you to be alerted in real time of the position of mobile or fixed speed cameras. The principle is always the same as for other speed camera warning software: users who see a speed camera or an unmarked car report it with a simple click on their phone screen.
The next driver who will pass in front of the same speed camera will then receive an alert which he can confirm in the same way.
The 2 drivers then gain an additional level of credibility on Trapster's online platform which centralizes and dispatches speed camera alerts.
