The app will initially detect whether you're within 10 km radius of the nearest AES cameras. Once your distance is less that 1 km, the app will use google map to determine the distance to the nearest AES cameras, making sure to alert you of relevant AES cameras and ignoring cameras not in your path.
The app require TTS to be installed.
This is still alpha, so test, test test.
Requires enabling GPS on your phone. Bonus - speedometer (that depends on strong GPS signal)
