The company first markets the police tracking unit to area law enforcement agencies and then appeals to car owners who would install the unit in the hopes their car would be recovered if stolen. For an additional fee, car owners can install a starter- disabler device. The system uses a lighted compass-type device that shows the area in which the stolen vehicle is traveling, a digital printout for information, and a description of the vehicle. The Police Tracking Computer provides the police officer, via the dispatcher, all pertinent information about the stolen vehicle. The LoJack monitor installed in patrol cars has a strength indicator that tells the officer if he is within one mile of the stolen vehicle, allowing time for back-up help to be called.
