GSM Intercoms offer a brilliant solution to communicate with visitors via a landline or mobile phone. The call panel will house a SIM card (Not usually provided, so pick the network with the best coverage in your area) which once programmed will call through a list of stored numbers until answered. A GSM Intercom can also be dialled in to grant access to the entrance it is fitted to.
