GSM Openers & Intercoms
GSM Intercoms are a wireless option that operate through a sim card installed in the intercom housing. Phone numbers can be entered into the sim card and programmed to a digit on the keypad for each customer, when that digit is pushed the GSM will ring that customers phone, either mobile of landline whatever is required.
The door or gate can be opened remotely by the customer from his or her phone keypad.
