I was sitting on a balcony in Honolulu, watching the sun melt into the Pacific Ocean, when my phone buzzed beside my iced tea. The notification was routine: Motion detected. Front hallway. I assumed it was my cat sitter or perhaps a package delivery. I opened the camera feed casually, barely glancing at the screen until I saw three people standing in my foyer—people who didn’t live there, people who had no permission to enter.
