Most sensors are small and quiet and report one thing. A door sensor says open or closed. A temperature sensor says a number. A presence sensor built on radar says whether someone is there. None of them captures pictures or listens to conversations.

Vaety. keeps sensing separate from cameras and speakers on purpose. Sensing is how your space becomes aware without watching you. When a camera or microphone is part of a design, for example a video doorbell, we say so, explain where its data goes and keep it away from private areas.

If privacy matters to you, sensors are the gentle way to bring intelligence in. Most of the experience, from lights that follow you to air that adjusts itself, can be built with sensors alone.
