Speci?cally, the current available equipment can be
categorized as localized alarm system protection, car
location systems and ?eet management systems. The
localized alarm protection systems activate a warning
device such as a siren when the car is broken into. Gen
erally speaking this type of system is effective only if the
car owner or the police are in the vicinity. Other people
tend not to get involved in this situation and in many
cases car alarm sounds are not being acted on by the
police. The pros are that they are inexpensive and in
some cases the warning device deters theft. The cons
are that if the owner is not around there is a high likeli
hood that no action will be taken to apprehend the
intruder. Also if the owner is around and is able to get
to the vehicle he may be risking personal injury or
worse, by the intruder. Car location systems will iden
tify the location of the car after the fact, that is some
time after the intrusion is detected and the car is driven
away from its parking spot. A good example of such a
system is disclosed by US. Pat. No. 4,177,466 to Rea
gan. While there is a relatively high likelihood that the
car will be eventually located, this type of system suf
fers from some distinct practical shortcomings, some of
which are technical and some of which are political.
The pros are that there is a relatively high livelihood
that the stolen car will be located and returned to the
rightful owner. The cons are that the car owner must
notify the police that his car is missing before the police
can take any search action. The problem is that if the
owner is not around it may take sometime before he
becomes aware that the car is missing and by then the
car may be extensively vandalized. Furthermore such a
system does not prevent nor deter stealing. Also be
cause the system such as disclosed by the Reagan patent
is based on esoteric infrastructure requiring very spe
cialized antenna sites and equipment, it is quite expen
sive. Furthermore the state police are very reluctant to
?nance such a system. As such the system is available
only in Massachusetts and even there the inventor had
to donate the required equipment to the police before
they were willing to use it. Furthermore, the car loca
tion system as disclosed in the Reagan patent utilizes
location stations having location indicators, the latter
comprising proximity detectors and/or radio direction
?nders. These location stations may be placed at ?xed
locations or carried by driver-operated ?nder vehicles.
