The baby movement monitor with video and sound is a reliable and trusted essential for baby care. With simple and secure technology that parents have relied on for 25 years, the latest monitor is equipped with additional features that provide you with a lot of security. The movement sensor pad is designed to be placed under your baby's mattress, where it can detect even the slightest movements completely contactlessly. The AC25 model has 4 adjustable sensitivity levels for individual tuning based on the mattress and environment. If no movement is detected for 15 seconds, the monitor emits an initial beep to wake your baby. If no movement is detected after another 5 seconds, an alarm sounds to alert you. Finally, the AC25 can also be used without movement detection for early toddler years.
