4.6.1.2 Mobile cameras
Some cameras are operated from vehicles. The database contains some typical

cameras, but as there is no speed limit given, only the proximity is announced.
These cameras are displayed with the following symbol:
4.6.1.3 Built-in cameras

These cameras are displayed with the following symbol:
4.6.1.4 Section control cameras
These cameras work in pairs, and do not measure your current speed but your
average speed between the two cameras. Both will identify your car, and record the
exact time you pass them. The difference between the two points of time will be used
to calculate your average speed.
MioMap will warn you when you approach one of these cameras, but as you pass
by, the warning stays on, and your average speed is measured until you reach
another camera of this type. If your average speed exceeds the speed limit between
the two cameras, you will receive the same special warning sound as with the other
camera types.
Note: In the rare case MioMap cannot register the moment you pass the second
camera (e.g. it is placed at the exit of a tunnel where GPS position is not yet
