The Nanit Breathing Wear Band in Grey works with the Pro Camera (sold separately) to safely and comfortably detect your baby’s breathing motion in almost any sleep position–without any sensors, electronics, or radars. Using patented computer vision technology, Nanit tracks breaths per minute (BPM) and responds quickly to changes by sending real-time alerts through the app and to the camera should your little one need you. Think of it as a gentle hand on your baby’s chest when you can’t be cot side. Monitors baby’s breath so you can catch a breath. The custom-designed pattern on Nanit Breathing Wear is tracked by the Nanit Pro and Plus Cameras to see your baby's breathing motion without any electronics or sensors touching your baby's skin 24/7. See your baby's breaths/minute in your Nanit app, in real-time. Should they ever need you, Nanit will sound an alarm on your camera and in your app. The Nanit Swaddle is comfortable for babies and comforting for parents, made from 100 percent cotton, no electronics, and is machine washable.
