How Does Police Laser (LIDAR) Work?
LIDAR is an acronym for Light Distance And Ranging. A LIDAR gun
emits a highly focused beam of invisible light, in the near infrared region
of light that is centered at 904nm of wavelength and is only about 22
inches (56cm) in diameter at 1000 feet (300m). Unlike RADAR which
directly determines a vehicle's speed by measuring its Doppler shift,
LIDAR calculates speed by observing the changing amount of time is
takes to "see" reflected pulses of light over a discreet amount of time.
7. Saving new co-ordinates
If in the unlikely event that you pass the location of a safety camera and
your Snooper Evolution does not provide you with an alert, the unit gives
you the opportunity to store the coordinates of the location manually.
Simply park safely as close as possible to the site and press and hold the
'New Location' button (button 3) for approximately two seconds. If the
voice setting on your unit is switched on the unit will confirm 'User data
stored' and the screen will display 'Save M' and the number of the
location in your unit's memory. The next time that you perform a
download you will get the opportunity to upload the new site for
verification. If the new coordinate is verified successfully the coordinates
will be added to our master database. Once you have uploaded a
coordinate to our database please delete it from your unit's memory
before uploading any further information.
If during the period before you perform your next download, you pass the
site again your Snooper Evolution will now alert you to the new location.
As the unit does not know what type of system you are passing the unit
will display 'User Pnt' and give either a voice alert stating the location as
a 'Risk zone' or your chosen audible alert. Your unit can hold up to 99
coordinates in its memory
Trouble Shooting - Saving new co-ordinates
When you attempt to save a new coordinate but the display reads 'Weak
Sgn' it means that your Snooper Evolution is not receiving sufficient
signal strength to plot the position. Please ensure that the Snooper
Evolution built-in GPS antenna has a clear view of the sky, the unit is
