As soon as we bought our home (4years ago) I started checking into Alarm companies. What I really liked about this company is that it is a live voice. It is real time. I have set off the alarm a few times and if I was in a home and not suppose to be it would make me run. The other best thing is that there is a safe word and a help word. Thank god I have only ever had to give my safe word. But if I ever need help I know these guys will be there live.
