But in contrast to a traditional baby monitor, the machine is linked to WiFi, Bluetooth and GSM. It enables parents and carers to keep a close eye on the child, wherever they are. The ingenious thing includes a sensitive microphone, speaker, sensitive camera and an advanced “micro power ultra-wideband radar” sensor that measures body movement and respiratory rate from a distance - even through the quilt in a dark room. As well as sleep rhythm, Ray can also detect worrying situations such as fever, asthma or bronchitis. The baby monitor can also indicate acute situations that could lead to suffocation.
