GSM intercoms are wireless systems that operate via mobile phone technology. It allows you to speak to visitors to your property and grant them access even if you’re not on the premises. The visitor uses the push button at the gate/door which then makes a call to a mobile phone. A GSM intercom can be linked to several phones and can be answered on or off the premises - even when out of the country!
