Teletrak was a better but more expensive system. It is a monthly expense, about $50. Using GPS, they can track your car. Used on commerical big rigs all the time.
Another system thats been out awhile was designed for tracking your kids. AllTrack (or something like that) allows you to use a laptop to find your kids or property. However, you are limited in how many times you can use the system. You pay yearly. Use to be like $125 for 12 uses. Size of an Ipod, you can hide anywhere.
