The wireless Baby Cry Sensor is part of the CentralAlert Notification System by Serene Innovations. It sends to the CentralAlert receiver to notify you when your baby cries. It monitors the baby sound in real time, stopping when the baby stops making noise. A 3-position sensitivity slide switch lets you set it to the optimal setting.
