At 3 A.M., My Brother Dragged Me Out of My Bedroom While Dad Laughed—He Had No Idea What the Smoke Detector Had Recorded

I understood that recording inside a private bedroom raised privacy and legal questions, so I was careful about what I intended to capture and later sought advice about the use and preservation of the material.

I wasn’t trying to record strangers or monitor the rest of the house.

I wanted to document access to my own room.

I installed the device above the bookshelf on February 8.

It faced the doorway, the dresser, and part of the bed.

The camera was unobtrusive.

Its recording indicator didn’t attract attention.

When I finished, I stood in the center of the room.
