GSM Intercom 

These GSM Intercoms are popular for locations where Wireless Technology struggles to work over the required distances.

These GSM Intercoms use mobile phone technology (SIM Cards) are can be used in any location to communicate with visitors and if needed to remotely operate a Lock or Automatic Gate/Door provided there is a suitable Mobile Phone Signal and a Power Supply.

The standard sized SIM Cards can be 'PAYG' or Contract, and we recommend you use a network that has a strong signal at the proposed location of the Intercom.

It does require a power supply in the form of a plug in transformer or direct feed from a Automatic Gate or Door circuit board.

They would normally be used in applications where the Caller Station is to far away from the House or Office to be able to use Wireless Intercom such as the UltraCom, they will also allow you to potentially open a Gate using a mobile phone from anywhere in the world.

We can supply GSM Audio Intercoms for single dwellings up to 99 Apartments !!
