What it is
Summary
AI-generated from vendor-published content · April 26, 2026
The BC400 is a wireless sound transmitter that picks up a baby's cries and sends a signal to a compatible Sonic Alert receiver elsewhere in the home — allowing deaf or hard-of-hearing parents to be alerted through flashing lights or vibration rather than sound. It plugs directly into a wall outlet near the crib, with an adjustable sensitivity dial so you can fine-tune how readily it picks up sound. This is only the transmitter half of a system — you must purchase at least one Sonic Alert receiver separately to actually receive any alert. Without the receiver, this unit does nothing on its own, so budget for the complete system before ordering.
