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 BC400 sends a signal over your home’s electrical system to remote receivers (see Miscellaneous Receivers), so it is completely wireless!

You can rest assured that you will always know when your baby is crying and needs you.

Please remember you need to use at least one remote receiver with the Sonic Sitter. The most popular receiver is our SB1000 alarm clock with built-in receiver.
