The Motorola MBP36S has a powerful microphone that keeps you alert to what's going on in your baby's room. This earned it one of the best audio scores on our lineup. It has decent connectivity even for large homes, though it suffered some lag in our tests. This also isn't the easiest baby monitor in our reviews to use, as the controls on the parent unit are a little confusing.
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.
