This Property Protected by NEST Alarm
(Google has already cleaned them out)
Not that long ago, a thermostat was just a thermostat. It was a beige box that was often installed by someone who came out to your house or office. It did what it did. Turned the heat on, turned the heat off. Had a schedule. Then came Nest, which promised to bring the ugly beige box into the internet era with sexy styling, …
What data is stored on the central nest systems, to whom is it sold?
What happens when the central nest servers are hacked and the custoimer data stolen?
What happens when a vulnerability is found which burglars can easily exploit perhaps even down to infoirming them when the best time is to burgle your house?
What heppens when the wifi is down?
What happens when your internet connection is down?
What happens when there is no power for hours?
And indeed as others have mentioned when the supplier decides to pull the plug.
Point of an external sounder is you need a ladder to disable it (at least until you can disable the alarm).
I've never seen any IOT review that actually covers what if's, they just seem to test the thing when everything works.
I'll stick for my self maintained alarm system for now, even that (and any such alarm) can be disabled within a few seconds by anyone who knows what they are doing.
if someone wants to be in they will be. That is what insurance is for.
PS. If your alarm sounds during a power cut its either a pile of junk or your batteries are dead. It's amazing how many go off, which makes them more likely to be ignored. Let us all have a good night's sleep and get the batteries replaces. Easy DIY job.
Reminds me of friend's neighbor, who had a nifty alarm with inside siren. The home was burgled with neighbors present on both sides and of course nobody could hear the alarm, because it was inside. An inside-only alarm goes beyond simple impoverishment of the imagination and reaches stupidity. (and forget the cops being dispatched; a real human hiding in a closet will produce a response time reaching greater than an hour, according to our own neighbor's report after her hiding in her closet for more than hour until the plods showed up after she called on a prowler).
"All things being equal, buy the Nest Secure. It is the best system we have used. It's a pleasure to use."
All the "good" points focus on how nice it looks and how friendly it is to use and just generally be around. Unfortunately, the bad points listed include being easily disabled by anyone who actually breaks into the house, not actually alerting anyone to a break-in or deterring burglars, and repeated losing connections to sensors. In other words, the good points are all irrelevant feel-good nonsense, while the bad points are that it fundamentally fails at its sole purpose.
Sadly, this is exactly the problem most security ends up having - there's always some trade-off between security and convenience, but since people have to deal with their own systems every day while malicious activity is relatively rare, they end up trading to the point that security is totally compromised. Just like using "password1" for all your passwords, Nest allows you to have the warm, fuzzy feeling that you're doing something useful without forcing you to put up with the inconvenience of actually being secure.
