It is true that there are only so many frequencies. But with modern 
alarm systems this is irrelevant. All current systems (unless they are 
total junk) use digitally-encoded signals with millions of unique 
codes. Moreover, most of them use "rotating code" schemes that protect 
against "captured" codes and other spoofing techniques.

The days when an airplane flying overhead could cause your garage door 
to open are long gone.
