Snuza Hero baby monitor is a wearable device which attaches to baby's diaper and monitors normal abdominal movement. The Snuza Hero is a vibrating movement monitor and will vibrate after 15 seconds in an effort to cause resumption of abdominal movement, this is then followed by a loud alarm. The Hero detects even the slightest abdominal movement and alerts you if your baby's movements are very weak or fall to less than eight movements per minute.
If no abdominal movement is detected at all for a period of 15 seconds, the Hero will vibrate gently. Often this vibration is enough to rouse the baby and Hero will revert to monitoring mode. After three vibration/rouse incidents, the Rouse Warning will alert you to the fact that your baby's abdominal movements have stopped for 15 seconds on three occasions. If no further movement is detected for another five seconds, an alarm will sound to alert you.
