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. Be sure to place the correct side of the Sensor Pad facing up.
The Angelcare Movement Sensor will give you the peace of mind you won't get from just a sound monitor or even a video monitor. And, this monitor is an excellent value. It is 2 monitors in 1 so you don't have to purchase a sound monitor.
The Movement Sensor with Sound Monitor includes an Under-the-Mattress Sensor Pad, a Nursery Unit, 2 Parents' Units (sound monitor) and 3 AC adapters. It can also operate with 12 AAA batteries (not included).
