 The October 1992 issue of Car Audio & Electronics has an article about
 carjacking and alarms.  Here is a quick rundown:

 1:  HOFCO PASSIVE HOLD-UP SYSTEM by Hofco Auto Security
     A hidden switch must be pressed within a certain time after the
     engine has started or after any door has been opened and closed
     while the engine is running.  The car will be disabled shortly
     thereafter.  A valet mode is included.

 2:  STOP THIEF by West Coast Car Audio
     A passive device that will disable the car within 20 seconds of
     engine start or if doors are opened after engine is running if
     hidden switch is not pressed.  If restart is tried, the car horn
     will start sounding.

 3:  SENTRY TOP-300 by KTK Engineering
     A passive device that will activate an inside piezo siren within
     30 seconds of engine start if hidden switch is not pressed.  That
     is followed by 30 seconds of lights flashing which is then followed
     by the underhood siren and engine kill.  Total time to engine kill
     is 90 seconds but if siren wires are cut, engine kill is activated
     immediately.
   
 4:  THE CARJACKER by ?
     An active device that requires the driver to push a button to start
     a time that will disable the car after 2 minutes.

 5:  CRIMESTOPPER's 9200M series of alarms (including the 9228MX,HP9235,
     HP9255) can be combined with the 785 "data link" and remote starter.
     Requires separate remote control to activate alarm.  After activation,
     siren will sound 2 minutes later followed 8 seconds later by activation
     of anti-hijack output.  The circuit could be used to control sirens,
     fuel cut-off, ignition disable, or other carjacking deterrents.
     WARNING!  Crimestopper advises against the use of toxic substances,
               biological or chemical agents, or explosive devices.  Damn! ;)

 6:  ALPINE offers an option to their 8080 Security System called the 8316
     Comunicator linked through the 8336 Security Data Interface that will
     allow the car owner to activate numerous functions via the Alpine 
     9542 Celluar Phone.  The Alpine celluar phone can also communicate
     directly with most other security systems.
 
 7:  CALLGAURD by Clifford.
     Offers the same features as the Alpine system but offers such extra
     features as disabling the engine only when the car comes to a stop
     like at a red light or stop sign and will call any preprogrammed
     number and with a synthesized voice, will announce the theft of your
     vehicle and its license plate number.

 8:  POSSE by Adaptive Vehicle Systems
     A pager activated device that will disable you car, flash lights, and
     sound the siren when it receives a special code.  A nation-wide,
     satellite based system that works wherever a paging system is located.
     Just dial a 1-800 number, punch in you secret code, and if your car
     is anywhere in North America, it will be "paged".

 9:  TELETRAC VEHICLE TRACKING SYSTEM by PacTel
     Audiovox, Code-Alarm, Kenwood, Mitsubishi, and Samsung offer electronic
     devices that work with the Teletrac system to locate your car anywhere
     in North America.  The system is accurate to within 100 feet.
     

 Hope this helps.
