The GSM-doorbell to remotely open your door
10 October 2006 by axxxr
Already on the market in the Netherlands, the Waleli GSM doorbell is a clever application for GSM mobile phone technology, allowing people to answer their doorbell, talk to visitors, and even open the door, whether they are at home or not. All via their GSM mobile phones.
The GSM Doorbell looks like any other doorbell you might find on a house. When a caller pushes the GSM Doorbell, it rings the resident’s mobile phone via the international GSM network. The visitor can talk to the resident via the small intercom panel next to the bell push.The GSM doorbell can also be linked to an electronic door release, allowing the resident to unlock the front door from the mobile phone keypad, using a secret code.
