Ok... while not the same thing (but close) I have used this device (and still do) on two bikes. My ST1300A and my Goldwing.
It works. Has reasonable range and has a couple of options.
As far as range goes, if I can see the bike from my motel room window, I am in range.
In my house, I am about 50 feet from the bike in the garage and I am in range.
I purchased this after my ST got "moved" one night by someone I think was a disgruntled friend of a young lady I was acquitted with.
Meet the SRX Hands-free motorcycle alarmhttps://ridescorpio.com/scorpio-secure/Like I said one of the units I have is right at 12 plus years old. It still works although the disloyal (LCD I think) has some issues but, I can still turn the alarm on and off and get alarms from the unit.
It allows for both motion (i.e. bike on side stand is move to a vertical position as well as proximity alerts.
Don't know how good it would be for a car but its an option.
