This doorbell links wireless phone technology and an electronic door lock to let you talk with someone at the door and open the door using your cell phone.
Made by the European-based Waleli company, the phone is being marketed in Northern Europe with plans to sell it internationally.
We see several aspects of convenience and safety. People with mobility issues could talk to the person at the door, and let them in, without actually having to go to the door.
And when you are away, you can give the impression you are at home because the doorbell still would ring your phone, whether you are at work, on vacation or while running errands.
You also could open the door from afar if you’re running late and guests come early or the plumber arrives and you’re at work.
