The product
The GSM-doorbell, what?s in a name? You can talk to a visitor at your front door through your mobile phone and even let them in remotely with your mobile phone.

• We forgot our home keys. Luckily we had our mobile phone with us.
• I love gadgets, the GSM-doorbell is my latest catch.
• I?m letting the cleaner in while I?m at the office.
• People don?t have to know I?m on holiday.
• I?d rather not put a key underneath the doormat.
• I just want to know what goes on at my doorstep while I?m away.

Is there a need? In the future everybody will be able to open their front doors from a distance. While the benefits are already so obvious! The GSM-doorbell provides more freedom of movement, knowing everything is under control at home.

How it works
After installing the GSM-doorbell life goes on as usual for the resident: When a visitor rings the doorbell the normal bell rings. The resident can however also choose to have the doorbell send a signal to their mobile phone whenever someone is ringing the doorbell. The resident can speak with the person standing at the door. The door can then be opened remotely with the mobile phone of the resident.

The concept
The concept of the product is simple, targeted and stand-alone. It uses technologies that are up-to-date and accepted. This makes the GSM-doorbell dependable, user-friendly and less pricy than complex home networks.
