DoorBot: the battery operated Wi-Fi video doorbell that connects to smartphones and tablets. See who is at your door -- anytime/anywhere. Pretty easy to steal though. ... Wi-Fi Enabled Smart Doorbell - DoorBOT
It looks interesting. Project link: https://secure.christiestreet.com/products/doorbot But at $170, or $320 with lock, I'm not sure if I'd like that. On the other hand, it's a pretty normal pricing for such products.
Owners may as well leave their front doors open 24/7 then, because it won't be long until someone walks right in, and takes everything. Especially when the batteries appear to be so easy to remove.
So a device connected to a system that most folk barely know who to secure sufficiently that can in turn be used ti unlock your house... ...so would I just not be better off leaving my door wide open and at least save myself the 200 quid?
Hmm as a doorbell, sure looks pretty neat but I would not want that thing to be locking/unlocking my doors.
