BebeSounds Angelcare Deluxe Movement Sensor with Sound Monitor

The BebeSounds AC401-2P Angelcare Deluxe Movement Sensor with Sound Monitor detects your baby's slightest movements, even while she sleeps. While it may seem that your baby is perfectly still when she is sleeping, she really isn't. An alarm will sound alerting you to check your baby only if she becomes absolutely still for 20 seconds and no movement whatsoever is detected: The under-the-mattress Sensor Pad detects your baby's slightest movements. If your baby goes absolutely still for 20 seconds, the Sensor Pad sends a signal to the Nursery Unit which sounds an alarm alerting you to check your baby. If you are out of the baby's room, the two portable Parents' Units (Sound Monitor) will pick up the alarm as well as other nursery sounds. In addition, the Nursery Unit has an optional "tic" feature. If the Sensor Pad senses movement, the Nursery Unit will continuously tick. If it doesn't, the ticking will stop. The two Parents’ Units give you the flexibility of always leaving one in your bedroom while moving the second unit to the room you are in while your baby is sleeping: Your crib must have a hard flat surface. If it does not, just place a piece of masonite or a board under the mattress and place the Sensor Pad on top of the masonite and under the mattress. You may order the BebeSounds ACM04 Angelcare Masonite Board separately. Be sure to place the correct side of the Sensor Pad facing up: Features: Detects your baby's slightest movements, even while she sleeps.
