If my system reports to derby City using my phone line, what happens if my phone line is cut or out of service?

That is a great question! Fortunately, Derby City Security has very flexible communication paths. You can either add a cellular radio as added line security or you can use an Ethernet connection as your main communication path. With the cellular radio there is no line to cut and it works under any conditions. These radios can be backups or primary communicators. With these options you can even eliminate your traditional phone line and enjoy further monthly savings.
