If you have regular landline “copper line” voice telephone service (Plain Old Telephone
Service), or if you have (Voice over Internet Protocol)  landline telephone service, from facilities-based private Internet Service Providers, (such as Comcast or Fios), your alarm system will communicate fine.

However, if you have telephone service from a non-facilities-based public Internet Service Providers (such as Vonage, T-Mobile, MetroPCS, Magic-Jack, Clear, or Skype) your alarm system will not communicate properly. For a detailed explanation of the “reasons why”, go to our home webpage and click on “Telecommunication Issues.”

If you do-not have any landline telephone service at all, your alarm can communicate through the internet, through specially designed “internet style” alarm communicators.

If you are concerned about the line security of telephone or internet providers, cellular is for you.

What if the “internet is down” or if a burglar cuts your incoming telephone line or incoming internet service where it enters the house?  Cellular alarm communicators are not tethered to any incoming telephone or internet lines.  With cellular, alarm signals can be received at the Central Monitoring Station despite any intentional or unintentional interruptions of telephone or internet service.
