Video baby monitors are simple, inexpensive tools for watching your child, and HD video is not a necessity for this task. While some baby monitors have excellent video, even those with lower quality video are suitable for watching your infant. Screen resolution does not necessarily mean good image quality, so we didn't use it as a point of comparison, relying only on video performance as observed in our tests.
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.
