6.5.10.1 Camera types
There are different types of Road Safety Cameras.
Icon Type Description
Fixed Some speed cameras
stand by the roadside, looking in one direction,
measuring one or both directions of the traffic. Th
ey measure your
current speed. For these speed cameras
you can specify the
controlled traffic direction and the speed limit.
Alpine Navigation
Software warns you when you approach these speed cameras
in the
measured direction. If your speed exceeds the spe
ed limit near the
speed camera
, Alpine Navigation Software plays a special warning
sound.
Mobile Some speed cameras are operated from vehicles. They do not a
lways
work and they are not set to check a preset speed limit.
The warning is
similar to fixed speed cameras
, but as there is no speed limit given,
only the proximity is announced.
Built-in
Some speed cameras are built into traffic lights.
They work like fixed
speed cameras, but they are difficult to spot.
The warning for proximity
and speeding is the same as for the fixed speed cameras.
Section control
These speed cameras
work in pairs, and do not measure your current
speed but your average speed between the two speed cameras.
Both
identify your car and record the exact time you pass them.
They use
the difference between the two points in time to calculate your average
speed.
Alpine Navigation Software warns you when you approach one of
these speed cameras
, but as you pass by, the warning stays on, and
your aver
age speed is measured until you reach another speed
camera of this type.
If your average speed exceeds the speed limit
between the two speed cameras
, you receive the same special
warning sound as with the other speed camera types.
In the rare case Alpine N
avigation Software cannot register the
moment you pass the second speed camera
(for example, it is placed
at the exit of a tunnel where GPS position
is not yet available) the
warning continues.
Just tap the speed camera symbol displayed on
the screen to stop the warning.
Tap again to display the second route event
with the possibility to open
the Itinerary.
Red light
These cameras check if you obey traffic lights.
The warning is similar
to mobile speed cameras
: as there is no speed limit given, only the
proximity is announced.
6.5.10.2 Camera directions
A speed camera can measure the speed of one direction of the traffic, both directions, or even several
directions in an intersection, when they are mounted on a rotating base. The same directions apply to
red light cameras. Alpine Navigation Software warns you only if you drive in a measured or possibly
measured direction. The measured direction of the camera appears with the following symbols:
Icon Description
The camera checks speed in the direction into which you are driving.
