What is a GSM Alarm Dialler?

GSM Alarm Diallers are fairly new to the market (i.e. the last 8 years or so) but in that time have shown themselves to be very useful and convenient either as an alternative to a standard Alarm Dialler or as a backup device.

In situations where it is not practically or financially viable to get a land line installed or where there is a high chance someone might try to block the line a GSM Dialler can be ideal.

A GSM Alarm Dialler is essentially the same as Landline Version but accepts a sim card and uses the GSM networks to make and receive alarm calls rather than PSTN land lines.

Not all GSM Diallers are equal most are very cheap and are not designed to cope with commercial or industrial use, nor will they have the features a business might require i.e. multiple dial out lists for different staff rotas. For example the Commercial M30 Autodialler by Packs Infotel can use both Landlines and the GSM network, i.e. The M30 can use the GSM networks all the time or the M30 can use the Land Line networks and only switch to the GSM / Mobile networks if the land line fails.

 

But you do need to be bare in mind that GSM / Mobile networks are typically less reliable than a fixed land line, as they are more susceptible to weather and local conditions and have a smaller network capacity. E.g. during peak times the mobile networks often become clogged and fall over. Governments also have the power to turn off or disrupt the GSM and or Mobile networks in an emergency.

Because of this if you application is critical we would recommend where ever possible to use a land line as the primary medium and use the GSM networks as a backup.
