There are security companies (like Smith Thompson in Dallas) that uses cell phone towers. You don't need landline for them. I also have Foscam that emails me whenever movement is detected. Also you can install monitor/security systems that are not monitored. You can still setup codes and arm system when away. It is just that if no one is monitoring the alarms, then no one will call police. But it should still scare away intruders.
