Like other systems, the Dropcam Echo allows you to put up more than one camera and monitor different rooms. The manufacturer says the Dropcam Echo automatically detects motion and sound, and you can get an e-mail message or notification on your smart phone or iPad when something changes in the baby's room. Dropcam will store your video feed for either a weekly or monthly fee.
It really depends on what you feel most comfortable with. There are audio monitors that allow you to listen to any noise coming from the nursery, vital monitors that track sleep and breathing and video monitors that add sight to sound. Babylist parents overwhelmingly choose video monitors. The security of seeing what your child is up to—like if they’ve gotten tangled in their swaddle, pulled their diaper off or climbed out of the crib—can be worth the extra cost of a video monitor.
