Re: The Big Question:
I was pondering this earlier today, when I saw that my neighbour has recently had one installed.
I couldn't think of a single occasion where my life had been negatively impacted by not being home when someone rang my door bell.
Most delivery people hide packages around my property (or throw them over the fence if it's Hermes), unless it requires a signature, which I can't do remotely through an e-doorbell anyway.
So all I'm missing out on is the cold-callers and the religious folk, shame.
Security wise, if you live in such a bad area that you need to video your doorstep, wouldn't a cctv camera covering the whole of the front of your house, with better quality video be a better option?
