I'm a fan of compustar alarms, but to answer you, AM is shorter range, and line-of-sight.
FM is longer range, and works better if you're obstructed from direct view of the vehicle, like inside the house, behind a hill, etc.
think of it like radio stations. AM craps out in tunnels. FM generally doesn't.
