The hallway camera has a five-second delay, so I watched myself leave the bedroom before I actually opened the door.

Voice Note
My sister sent a voice note asking me to stop calling her from the basement.
Doorbell
The doorbell camera showed a man waiting on my porch with his back to the lens.
Motion Alert
The motion alert showed a woman standing motionless in my backyard at 2:11 a.m.
Baby Monitor
My wife keeps complaining that our baby monitor wakes her whenever I come home from the night shift.
Face ID
My phone unlocked with Face ID while I was asleep alone in the apartment.
