The Waleli GSM Doorbell is a bit of a genius product which combines mobile phone technology and an electronic door lock to let you chat to a visitor and open your door using a cell phone handset. The wider implications are immediately obvious, are they not Holmes? Being able to open the door from afar when youre running late and your visitors are early, opening the door to workmen while you are at your office, that kind of thing. http://www.gsmdoorbell.com/ http://www.waleli.com (meer) (minder)
