LoJack is one of the
vehicle tracking systems out in the market developed and manufactured by LoJack Corporation. Its name, LoJack, is a rather comical derivative of the term "hijack".
LoJack is an extremely effective form of a vehicle tracking system. It markets itself as 90% effective in terms of vehicle recovery rate, and actual tests seem to support this statement. One particular study showed that the use of LoJack and other similar systems not only prevents carjackers from getting away but also decreases the occurrence of car thefts in general.
