Most security systems are designed around intruders. But you’re not an intruder. Nest Secure is easy to live with. And it’s only tough when you need it to be. You can choose how much time you need to arm or disarm before the alarm goes off – up to 5 minutes. For doors you use most, you might give yourself more time. For doors you hardly use, you can set No Delay so the alarm goes off instantly when it opens.
