Built-In Cameras; Section Control Cameras - HP 914c - iPAQ Business Messenger Smartphone Navigation Manual

Built-in cameras

Some cameras are built in traffic lights. They work like fixed cameras, but they are
difficult to spot. The warning for proximity and speeding is the same as for the fixed
cameras.
These cameras are displayed with the following symbol:

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.
HP iPAQ Trip Guide 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 HP iPAQ Trip Guide 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 available) the warning will continue. Just tap the camera symbol
displayed on the screen to stop the warning.
