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.
If you sleep in the same room as your baby or live in a small enough space that you can always hear or see what your baby is up to, you probably don’t need a monitor. Otherwise, most parents enjoy the convenience a baby monitor provides—instead of needing to stay close to the nursery or constantly checking on your child, you’re free to rest, catch up on Netflix or get things done around the house during naptime. Monitors can also double as a nanny cam to keep an eye on your child and their caretaker.
