This Baby Cry Notification package from Bellman & Symfon is part of the Visit Smart Home System that helps you to keep tabs on your home. This package includes a Baby Cry Transmitter, Pager Receiver, Charger, and Bed Shaker. The alerting devices in this package are already paired as a system and ready to use out of the box. When the Baby Cry Transmitter detects the cries from your baby, you will be alerted with vibrations and a colored LED signal from the Pager Receiver. The Pager Receiver is powered by a single rechargeable battery making it easy to carry with you in your home. This means that you can move around freely but still be available for your baby. During the night, by putting the Pager Receiver into the Charger and attaching the Bed Shaker, you will be alerted by strong vibrations from the Bed Shaker, which will wake up even the heavy sleepers. This Baby cry detector notification package is a great signaling system to help people in difficult listening situations, Hard-of-Hearing, and the Deaf to be informed when their lovely baby needs attention.
