Many parents find that a basic sound product more than meets their needs. They plan to run to baby's aid each time they hear them cry, and they don't need to spy on their baby with video. Using a sound option is the cheapest way to go to get a quality product that works well. However, if you need or want to see your baby, then a video option is the only way to meet this need. Choosing a Wi-Fi option means no concerns about range, the ability to see your baby when you are away from home, and usually better image quality. Wi-Fi also means you'll be able to use it for longer as potential security or nanny cam; this adds value you may not be considering right now (but should). Movement monitoring options are a luxury that most parents can do without. If you're worried about your little one and SIDs, studies show that having a baby sleep in their own bed in your room (along with standard safe sleep practices) goes a long way in helping to prevent SIDs and could potentially be more effective than movement monitoring. Choosing a great beside bassinet may be a better solution than a movement product. However, if your heart wants a movement product, then be sure to consider a sound or video option to pair with it so you can be sure to hear the alarm from another room.
Motion and audio sensors: In the old days, parents were forced to endure a consistent ambient hiss from their audio monitors while they listened for their child’s stirrings or cries. Mercifully, many modern baby monitors will stay in “quiet mode” until they detect motion and/or sound, which will trigger an alert, such as activating the handheld video display or pushing a notification to your smartphone.
Ease of setup and installation factored heavily into our ratings, including whether an account needed to be created and if there were any extra subscription fees necessary. Each unit had cords protruding out of its back, so design wasn't much of a factor in my choice, though parents should take care to keep dangling cords and wires away from their children's reach when setting up a monitor.
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.
