The core tension is simple:
Never record anything you wouldn’t want a stranger to see – because without proper security, a stranger might.
You install a camera in the nursery to catch a negligent babysitter. The babysitter is fine, but three years later, a hacker accesses the camera and records your child dressing. Or, a family member leaves the camera on while you walk through the room in a towel. The risk of self-surveillance is rarely considered.
