How to Choose a Baby Monitor in 2026

On a product grid, baby monitors mostly look like the same object at three prices. The published specifications say otherwise. How the monitor connects, how far that connection is rated to reach, what you actually look at, and whether you can talk back are four separate decisions — and they are what separate an audio-only unit from a Wi-Fi camera.

Connection type is the spec every other one follows from

The three monitors here use three different radio approaches, and the choice cascades into everything else. DECT 6.0 and FHSS are closed links between a baby unit and a parent unit: they pair with each other and nothing else, never touch your router, and involve no account or app. Wi-Fi works the other way — the camera joins your home network and the picture reaches you through a phone app.

That single difference decides whether the feed can leave the building: a closed link cannot be viewed from work at any range, and a Wi-Fi camera cannot work during an outage. Where it stops mattering is inside one house, with the parent unit in your hand — all three carry audio perfectly well. Connection type is about reach, not clarity.

Range figures describe open air, not your house

Two of the three publish a range, and they publish the same one: up to 1,000 feet. Infant Optics adds the qualifier that matters — line of sight — and it applies to any radio figure in this category whether or not the manufacturer prints it. Plaster, floors and a busy 2.4 GHz band all take a share, so the indoor figure is a fraction of the published one.

Because both closed-link units publish the same number, range is not what separates them — it is what tells you whether either suits your layout at all. Nanit publishes no range figure, which is accurate rather than evasive: the camera is on your Wi-Fi and the phone is wherever you are, so there is no distance between two units to rate.

What you watch on, and what keeps it running

This is where the three diverge most visibly. The VTech has no screen, reporting the room through a 5-level LED sound indicator and running up to 8 hours cord-free. The Infant Optics has a 5-inch HD screen on a handheld with a user-replaceable lithium-ion battery. Nanit has no parent unit at all: the camera runs on mains power and the picture lives in an app.

A dedicated parent unit does one job: it does not ring, and it can be handed to a babysitter without an account. A phone app has no parent-side battery to plan around, but it puts the nursery on a device doing forty other things.

Neither Infant Optics nor Nanit publishes a parent-side runtime figure, for opposite reasons: one has a battery it does not rate in hours, the other has no battery to rate. What Infant Optics does publish matters more over a few years — that the battery is user-replaceable, which decides whether a worn-out cell means a new cell or a new monitor.

Two-way talk is narrower than it sounds

Two of the three publish two-way talk; the VTech does not feature it. What it changes is specific: you can say something into the room without opening the door and restarting the settling process. That is useful with a toddler who wakes and calls out, and close to useless with a newborn, who needs you to come in anyway. It is a feature that arrives with a certain age rather than one that makes a monitor more capable.

Matching the specs to your home

The useful question is which constraint binds hardest in your house.

• Nothing in the nursery should be on the internet — connection type settles it; the closed-radio units never leave the building.
• Someone needs to check in from outside the house — connection type again, the other way. No amount of range turns a closed link into a remote feed.
• The nursery is two floors up, or across a yard — read the range figure with “line of sight” attached and assume a large indoor discount.
• A sitter or a grandparent will use it — a dedicated parent unit needs no account, no app and no phone.
• You want a picture but not a subscription decision — local video keeps that question off the table.

Frequently asked questions

Do I need a video monitor, or is audio enough?

It depends on your comfort level and your baby’s age. Many parents start with audio only during the newborn stage and add video once the baby is mobile in the crib, because visual confirmation becomes more useful as movement increases.

Are Wi-Fi baby monitors safe from being hacked?

Any Wi-Fi device carries some risk if it is not secured properly, so use a strong unique password, turn on two-factor authentication where it is offered, and keep the app and firmware updated. Nanit publishes 256-bit AES encryption for its stream. Monitors on a closed radio link avoid the question entirely, because there is no account to compromise.

What range should I actually expect indoors?

Considerably less than the published figure. Manufacturers rate these links in open air — Infant Optics says so directly with “line of sight” — and walls, floors and other 2.4 GHz traffic all reduce it. Wi-Fi monitors sidestep the comparison rather than winning it, since they depend on your router’s coverage instead.
