home alarm systems?
What is the point of having a home security alarm system, all a thief would have to do is cut the outside telephone line and than when it triggers the alarm company would not get notified, and no police would respond.

Greetings..
Most modern systems use a line signal that when it is dropped (like a cut line) triggers the alarm at the monitoring station.
Some still use dialers….but they have your mentioned short fall.
Now ya know…
