The device is designed to placed on the wall from where it can model a home in 3D, detect motion, sense a fall, and automatically place a call for help without requiring a wearable. Walabot Home does not require further action once it's been set up and can work in a wide range of conditions that cameras cannot, including steam and darkness, and can sense through objects like curtains and glass walls. It costs $250 and doesn't include any monthly subscriptions.
