This blog is temporarily converting to a consumer review site (today only).
I just bought a new door bell - not just any door bell. Because both of us work in outbuildings, we kept missing callers, and wireless door bells didn't have enough range. This one is wifi connected, so it rings on your phone wherever you are. And then there's a camera and a mike.
So a builder called while I was in Birmingham, and I could speak to him. Freaked him out when my voice appeared, but we got over that. Actually, this looks like being an issue with some of the other brands which have very obvious cameras, but just don't look like door bells. This one is branded 'ring', which also works as an instruction, of course.
It's very expensive for a door bell but brilliant. And what branding people call the 'out of box experience' was great too.
They gave me all the tools I need, down to the bubble thing to make sure I installed it level. And the app was equally good.
