Security Alarm Connection Options for Monitoring

Monitored alarms have traditionally communicated using copper landlines but new technology and the introduction of fibre has revolutionized alarm monitoring. As more people opt to remove landlines in favour of naked broadband and VoIP phone systems, communication units have been developed to enable alarms to communicate via the internet and cellular networks. There are several factors that determine what communication options are available to you, and which type best suits your needs.


Any copper phone or fax line that is connected to an alarm system will remain a reliable way for the alarm to communicate for monitoring. If you have changed to a fibre landline you may have had the option to install an adaptor that enables older phones, modems and alarms to continue working over fibre. Traditional phones and alarms do not work over fibre unless an adaptor is supplied.


IP stands for ‘Internet Protocol’. IP units use your own internet connection so require no additional monthly monitoring charges, but it is vulnerable to the reliability of that connection. It can only be used in buildings where it’s possible to run a cable from the alarm panel to the modem. This type of unit is often the most affordable, but depending on how far cable must be run, installation costs can add up.


These units use 4G, 3G or GPRS mobile networks to send signals. Mobile network units cost slightly more but can be wireless so installation time may be reduced. There are two sim cards in the units and one or both can be activated so the alarm system can utilize whichever network is available. This unit won’t be affected by a brief power cut as it can run off the back-up battery installed in the alarm. There is a small additional monthly fee for monitoring if you choose this type of unit; however it remains much more affordable when compared to phone line rental fees.
