Baby monitors have quietly become one of the more expensive line items on a registry, and a lot of that cost buys features that sound essential in a store aisle but rarely change how you actually use the thing. Before comparing specific units, it's worth being honest about which of the three main types you need.
Audio-only
For a small home, or a nursery close to where you spend your evenings, a simple audio monitor is often genuinely enough. The main thing to check is range — manufacturer-stated range is measured in open air with no walls, so a monitor rated for 1,000 feet might struggle at 40 feet through two interior walls and a floor. Look for reviews that mention real-world range in a multi-story home, not just the spec sheet.
Video
Video earns its keep once a baby starts pulling up, rolling into unusual sleep positions, or you find yourself walking to the room just to check something a sound alone can't tell you. The features that matter most in practice are a wide field of view (so you're not missing the baby when they roll to the edge of the frame) and clear night vision, since almost all the useful footage happens in a dark room.
Resolution numbers on the box matter less than people expect — a monitor with a smaller screen but reliable night vision and a stable connection beats a higher-resolution one that drops the feed every time a microwave runs.
App-connected (WiFi) monitors
These trade a dedicated handheld unit for viewing on your phone, which is genuinely convenient for checking in while out of the house, at the cost of two things worth weighing: a dependency on your home WiFi staying up, and video that at some point passes through the manufacturer's servers. If you go this route, it's worth spending five minutes reading the company's privacy policy for how long footage is retained and whether it's encrypted — this varies far more between brands than the marketing pages let on.
What to check regardless of type
- Battery life on the parent unit — a monitor that needs charging every night is one more thing to forget.
- Two-way talk, if you want to soothe from another room without walking in.
- Temperature and humidity readout — a genuinely useful extra that adds little to the price on most models.
- How it fails — check whether the monitor alerts you to a dropped connection, or just goes silent. A silent failure is far more concerning than a loud alert.
The honest recommendation
Start with audio-only if budget or simplicity matters, and upgrade to video only once you have a specific reason to want it. Most families who buy a top-tier video monitor before their baby is mobile find it spends most nights showing a still, quiet crib — useful for peace of mind, but not the feature they end up relying on until months later.
