How to Choose a Baby Monitor: Audio, Video, and Movement

Baby monitors range from a simple sound-only speaker to a full video system with a phone app. The right one depends on your home’s layout and how much information you actually want.

Audio monitors

Audio-only monitors are the simplest option: a parent unit that picks up sound from the nursery. They’re generally more affordable, have longer battery life, and don’t rely on Wi-Fi. The trade-off is that you only get sound, not a visual check.

Video monitors

Video monitors add a camera and screen, either on a dedicated parent unit or through a phone app. They’re useful for larger homes or when you want to see sleep position or activity without opening the door. Check whether the monitor uses a private local signal or streams through Wi-Fi and an app, since that changes the privacy considerations.

Movement monitors

Movement or motion monitors track breathing or motion through a sensor pad or wearable. These are a separate category from audio/video monitors and are generally intended as an added layer of monitoring, not a medical device — check the specific product’s stated purpose and limitations before relying on one.

Range and interference

Check the manufacturer’s stated range and consider your home’s layout — thick walls and multiple floors can reduce effective range regardless of the number printed on the box. If you live in an area with a lot of nearby Wi-Fi networks, a non-Wi-Fi audio or video monitor can avoid some interference issues.

What to check before buying

• Battery life on both the parent and baby unit
• Whether the app (if any) requires an account or subscription
• Encryption or local-only signal, if privacy matters to you
• Mounting options if you want a fixed camera angle

Bottom line

Audio monitors are the simplest and most battery-efficient option. Video adds visual reassurance at the cost of complexity and sometimes Wi-Fi dependence. Movement monitors are a separate, additional layer — not a replacement for either. Pick based on your home layout and how much you want to see versus just hear.
