GSM technology has come a long way since the first mobile phone. We can now offer a GSM intercom removing the need for signal cabling from the entry panel to the property, especially useful when the distance from the gate to your house is a large distance requiring larger diameter wires.
These panels are the intercom equivalent of a mobile phone, calling preprogrammed telephone numbers when the call button is pressed. The receiver of the call can open the gates by entering a code into the telephone.
Prior to installation of a GSM intercom you will need to ensure that the signal of your chosen sim provider is strong,. These units will work with a contract phone or pay as you go, the choice is yours.
Obviously this intercom offers you a greater operating flexibility than the hardwired intercoms as you can have the panel ring your mobile phone.
