This intercom knows no limits, in distance that is. It uses a mobile phone Sim to call a number and enables you to talk to your visitors at the gate/barrier and open it from your telephone. Divert functions allow the call to be diverted if the main line is not answered. Peace of mind that your visitors will always be able to gain access.Download Our GSM Intercom Guide
