alarms. Because LIDAR transmits a much narrower beam than does radar,
it is much more accurate in its ability to distinguish between targets and is
also more difficult to detect. AS A RESULT, EVEN THE BRIEFEST AND
WEAKEST LASER ALERT SHOULD BE TAKEN SERIOUSLY.
There are limitations to LIDAR equipment. LIDAR is much more sensitive
to weather conditions than RADAR, and a LIDAR gun’s range will be
decreased by anything affecting visibility such as rain, fog, or smoke. A
LIDAR gun cannot operate through glass and it must be stationary in order
to get an accurate reading. Because LIDAR must have a clear line of sight
and is subject to cosine error (an inaccuracy which increases as the angle
between the gun and the vehicle increases) police typically use LIDAR
equipment parallel to the road or from an overpass. LIDAR can be used
day or night.
HOW SAFETY SIGNALS WORKS
FCC-approved Safety signal transmitters emit microwave radar signals to
indicate the presence of a safety-related concern. Depending on the
frequency location of these signals as set on the transmitter, the outgoing
signal can indicate whether the transmitter is located in a speeding
emergency vehicle, at a road hazard location or at a railroad crossing.
These dual-frequency microwave signals are located in the K-bandwidth
and, as a result, any radar detector which detects K-Band radar will detect
these Safety signals as standard K-Band radar alerts. However, unlike
standard radar detectors, your SOLO is designed to distinguish between a
standard K-Band alert and a Safety signal alert. It will also demonstrate
which type of Safety signal is being received: Emergency Vehicle, Road
Hazard or Railroad.
Since Safety technology is relatively new and the number of transmitters
in operation is not yet widespread, you may not receive Safety signals on
a daily basis and should not be surprised to encounter some emergency
vehicles, road hazards and railroad crossings that are unequipped with
these transmitters and, therefore, fail to provide a signal. As Safety
transmitters become more prevalent (the number of operating transmitters
is growing every day), these Safety signals will become more common.
