Baby monitors range from about £13 for a mount to nearly £200 for a two-camera kit, and the spec sheets all lean on the same handful of numbers — range, resolution, "AI detection" — to justify the gap. Most of those numbers describe conditions you won't actually be in. Here's what to check instead, and the questions the spec sheet itself never answers.

Step 1. Video or Audio: What You're Actually Choosing Between

An audio-only monitor (usually DECT wireless, like the Hubble Audio Baby Monitor) transmits sound and nothing else — no camera, no screen, no app. A video monitor adds a camera feed you can look at, plus whatever extras sit on top of that feed: night vision, room temperature, zoom.

Audio suits parents who want reassurance without a screen to glance at every few minutes — it's cheaper, simpler to set up (no camera angle to get right), and there's less to check obsessively at 2am. Video is worth the extra cost specifically when you want to see what's happening — twins in separate cots, a baby who's started rolling or pulling up, or any situation where sound alone leaves you guessing.

Step 2. WiFi vs No-WiFi Is a Privacy Trade-off, Not a Feature Tier

A no-WiFi monitor talks to its own screen directly — no router, no cloud account, no app login. A WiFi-connected monitor either adds an app on top of a local screen (hybrid) or, on some models, drops the local screen entirely and works only through the app.

Neither connection type is "better" in the abstract. If you're mostly in the house and would rather have one less account tied to a camera pointed at your child, a no-WiFi model does the whole job on its own. If you regularly need to check the nursery from another room's WiFi, downstairs, or away from the house entirely, that's specifically what WiFi buys you — check whether a model keeps its local screen alongside the app (hybrid) or drops it in favour of app-only, since that changes what happens if your WiFi goes down.

Step 3. The Range Number Is Measured Outdoors, With Nothing In Between

A "3000ft" or "1860ft" range claim is a maximum, tested with a clear line of sight — not through the walls, floors and furniture of an actual house. In practice, a monitor rated to 1860ft outdoors and one rated to 3000ft will usually behave almost identically through two floors of a UK home, because walls — not distance — are what actually cuts the signal.

Don't choose on the range number alone. For most homes, the real question isn't "how far" but "how many walls" — a monitor with a lower outdoor rating but a clean line through your specific floor plan beats a bigger number you can't verify before buying.

Step 4. Screen Size and Camera Count Solve Different Problems

A bigger parent-unit screen (5"–5.5" against a 2.8" entry-level display) makes it easier to actually see detail from across a room — whether a baby's face is covered, whether they're genuinely stirring or just settling — without picking the unit up. It's a real upgrade, not just a bigger number, but it usually comes with a larger, less pocketable parent unit.

A single-camera kit covers one room. Two-camera, split-screen kits exist for two real reasons: twins in separate cots, or watching both the crib and a second space — a play area, an older sibling's room — from one screen. Check whether a second camera can be added later rather than only bundled upfront — several of the systems here sell a matching add-on camera separately, so starting with one and expanding when you actually need it is usually possible without replacing the screen you already own.

Step 5. "AI Cry Detection" and Mounting Are What You're Really Paying For

AI cry and motion detection isn't a hidden microphone upgrade — it's software watching the same camera feed and audio the monitor already has, flagging movement or sound faster than a human glancing at a static screen would. It reduces missed moments; it doesn't replace checking the screen yourself.

Mounting matters more than most buyers plan for. A floor stand needs floor space next to the cot but works on any surface with no fixing; a clip mount needs something up to about 2.2 inches thick to clamp onto — a cot rail, a shelf edge, a headboard — and takes no floor space at all; a crib mount fixes directly above the cot for the most consistent angle but commits the camera to one spot. Check what's actually next to where the camera needs to sit before assuming any of the three will fit.

Step 6. WiFi Security and Battery Life Are Worth Asking About Before You Buy

A WiFi-connected monitor routes its video through an app and, usually, a cloud account — which means it's only as secure as that account's password. Use a unique password and turn on two-factor authentication if the app offers it; a no-WiFi model sidesteps this category of risk entirely by never connecting to the internet in the first place.

Battery capacity determines whether "portable" is actually true day to day. A 6000mAh-class battery, common on no-WiFi parent units, typically runs a night or more before needing the charger, so the unit can genuinely move room to room. App-only WiFi cameras are usually designed to stay plugged in permanently, since a continuous video stream draws far more power — check whether a model is described as battery/portable or mains-only before assuming you'll be able to move it around freely.

FAQ

How long do you actually need a baby monitor for?
Most parents use one through roughly the first 12–18 months, while a baby sleeps in a separate room but isn't yet reliably able to communicate that something's wrong. Many stop once a child moves to a toddler bed and can get up or call out on their own. There's no fixed cut-off — it tracks a parent's own reassurance needs, not a safety requirement that ends on a specific date.

Do baby monitors actually work through multiple floors and walls?
Most maintain a usable signal through a typical UK house's ceiling and one or two interior walls, but exterior or load-bearing walls, and anything metal-framed, can cut range sharply — see Step 3. If you're monitoring across more than one floor plus several walls, it's worth confirming the specific model holds up in your own home during any returns window, rather than relying on the outdoor range rating.

Is a WiFi baby monitor a real hacking risk?
It's a real category of incident — compromised camera feeds have made UK news — but it's overwhelmingly tied to weak or reused passwords and skipped firmware updates, not a flaw unique to baby monitors. A unique password and two-factor authentication (where the app supports it) address most of the actual risk; a no-WiFi model avoids the category entirely.

Can you add a second camera later instead of buying a two-camera kit upfront?
Often yes — several systems in this range sell a matching add-on camera separately that pairs with the same parent unit or app account, so starting with a single-camera kit and expanding later is usually possible without replacing the whole setup. Check the specific model's product page for a matching add-on camera before assuming you're locked into what's in the box.
