The Sonic Sitter Baby Cry Transmitter, model BC 400, is a small, attractive unit that immediately alerts you when your baby starts crying. The BC400 has an adjustable sensitivity control, and can be set to alert you to sounds as soft as a baby's whisper. The BC400 simply plugs into any outlet in the baby's room. So your baby is not disturbed, no lamp flashes in the baby's room. When your baby cries, the BC 400 sends a signal over your home's electrical system to Sonic Alert remote receivers, so it is completely wireless! You can rest assured that you will always know when your baby is crying and needs you. The Sonic Sitter also has a built-in indicator light to show you it's working. Please remember you need to use at least one Sonic Alert Remote Receiver with the Sonic Sitter Transmitter.
