Um, our doors have multipoint locking. You lift the handle and multiple prongs, effectively round steel deadlocks, all round the door slot into the metal around the inside of the door frame. The whole thing is steel. I've been into the one on the back door because whoever installed it aligned all the bolts to the very top of the slots and wood moves with the seasons. I have moved the strike plates up and down by drilling new screw holes for them. I have even had that door off, it is HEAVY.
Watch the police reality shows or the news. When the police are faced with a new multipoint locking door they don't even try to bust the lock, they use the ram to take out the middle panels instead. They are the only weak point of such doors.
How is Nest going to effect that? are its servos strong enough? My wife isn't always, it sometimes needs an extra shove before the key will turn.
So, to install a Nest door lock I must downgrade my door's physical security. No thanks. The window salesman made a point of noting that their sealed units are under pressure from the gas inside. If they get broken it sounds like a gunshot. They are multi point locked in the sashes too. They are insurance rated when locked into the partly open position.
Burglaries have and are going down because homes are becoming impregnable unless you leave a window open for an opportunist thief. That is why muggings and grabbing stuff from the backs of scooters are going up. We are no longer so vulnerable in our homes so the yoof have to target us on the hoof instead of burgling us.
