Do I need a conventional telephone line for your alarm system to work?

On new installations, we generally DO NOT use a wired telephone line connection any more.  Every day at least one of our customers does away with a landline telephone connection.  Today’s technology allows us to utilize the cellular data network and/or the internet to send alarm signals.  Cellular has the advantage that there are no outside lines that can be cut or tampered with.  A combination of internet and cellular is the absolute best for assured alarm transmission in the event of a compromise attempt.
