GSM Intercoms

GSM - Wireless audio intercoms


GSM intercom panels are mobile phones built inside an entry panel. They need only a power supply. When the call button is pressed, it calls the stored number (the householder). If the landline is busy, or unobtainable, it calls a 2nd number, and even a third. Once connected, the householder can open the door or gate by pressing a prescribed key on their phone.

Various finishes are available. Modular panels on apartment blocks may have over 20 call buttons, each programmed to a different set of numbers.

A unique feature of GSM intercoms is using caller ID as an access code. Friends and family who know the intercom's SIM card number only have to dial it to open the gate. The line is dropped as soon as the intercom recognises the caller.
