Basics Of Car Tracking Systems

Each year, over 1 million vehicles are stolen in the U.S.
Most of them are either never retrieved or found only after having been stripped
for parts. Decades ago, if your car or truck were stolen, you were forced to
rely upon the diligence of your local police department. By the time they found
it, it was often damaged or stripped past the point of repair. Today, millions
of drivers have invested in auto tracking units. If taken, the vehicle can be
tracked instantly and recovered before it sustains damage.
In this article, I'll explain how these systems work and how they help the
police locate stolen vehicles. Then, I'll describe a few additional benefits
that may encourage you to purchase one.
How They Track Your Vehicle
We've talked about GPS devices in the past, including the technology that allows
them to function properly. Auto tracking systems use GPS technology and combine
it with cellular functionality to monitor location and movement. You may
remember that most GPS receivers require a signal from 4 satellites in order to
pinpoint location. Your auto tracker only needs 3 to work. Once the 3 signals
are received, the cellular technology built into the system sends your vehicle's
coordinates to the service which monitors its whereabouts.
There are some hurdles, however. For example, the satellites which send the
signals are often unable to penetrate concrete. So, if a thief has parked in the
lower levels of a concrete garage, the tracker may not work. Also, there are
plenty of "black out" spots which lack cellular coverage. Even if your tracking
system receives the 3 satellite signals, it may not be able to transmit the
coordinates to your monitoring service.
Reasons To Buy A Tracker
The obvious reason to buy an auto tracking system, of course, is to provide the
police with one more tool with which to locate your vehicle in the event that
it's stolen. But, there are other advantages. For example, the popular LoJack
unit allows you to track your car's movement on your laptop. If you're a parent
with a teenage child who borrows your car for the evening, you can confirm his
or her whereabouts easily. Some systems can even be programmed to email you
automatically when your car arrives at a predetermined location.
Another advantage of equipping your car with a tracker is that your insurance
rates will decrease. Auto insurers consider the potential theft of a vehicle to
be a significant financial risk. A tracking unit that leads to a quick recovery
reduces that risk, which rewards you with lower rates.
These systems aren't cheap; they can cost several hundreds of dollars. However,
they may save you thousands of dollars over the long haul.
