Baby monitor app vs dedicated monitor: honest comparison

The three kinds of baby monitor, and who is writing this

Team Nanuka wrote this page, and Nanuka makes a baby monitor app, so read the app column with that in mind. We say plainly where an app loses. The comparison is between three categories, not between named products.

1. An app on two devices you already own. One phone or tablet stays near the crib as the camera. A second phone or tablet is the screen. The app connects the two.
2. A dedicated radio monitor with a parent unit. A camera (or just a microphone) and a separate handheld screen, sold as a pair. They talk to each other over their own radio link. No Wi-Fi, no app, no account.
3. A Wi-Fi camera monitor with a cloud app. A camera that joins your home Wi-Fi and sends video to the vendor’s app on your phone, usually through the vendor’s servers.

Retailers often lump the last two together as video monitors. They behave very differently when the internet drops and when the vendor stops supporting the product, so this page keeps them apart.

Side by side: the same ten points for all three

The table below scores each category on the same ten points. Depends on the app means the answer changes from one app to the next, so check the specific one.

	App on two devices you own	Radio monitor with parent unit	Wi-Fi camera with cloud app
Cost to start	Free or a small subscription; a stand and a charger	The price of the camera and parent unit set	The camera, often plus a subscription for cloud features
Needs internet?	Usually yes, on both devices	No	Yes, for the camera and for your phone
Works during an internet outage?	Usually not	Yes; it does not use the internet at all	Remote viewing stops; some cameras keep a home-only view
Range	No distance limit while both devices are online	Within the home and garden; walls and floors shorten it	No distance limit while the camera and your phone are online
Who can see the video	Depends on the app: device-to-device apps keep it between your two devices; cloud-based apps route it through the vendor	Only the paired parent unit	You, the vendor’s servers, and anyone who gets your account password
Night vision	Depends on the phone; most phone cameras show very little in a dark room	Usually built in (infrared)	Usually built in (infrared)
Battery and power	Both devices plugged in; the one at the crib is tied up all night	Camera plugged in; parent unit runs on its own rechargeable battery	Camera plugged in; the phone you watch on drains faster
Extra features	Varies; cry detection is common, two-way talk and lullabies only in some apps	Two-way talk, lullabies and a room temperature display are common	Two-way talk, lullabies, sleep logs and cloud recording are common
Portability and travel	The same two devices work anywhere with a connection	Pack the camera, the parent unit and two power adapters	The camera needs a Wi-Fi network at the destination
When the vendor shuts down	Updates stop; device-to-device apps keep working until an iOS update breaks them; cloud-dependent apps stop	Keeps working; there is nothing to shut down	Remote viewing and cloud features can stop on a date the vendor sets

Two rows deserve a note. Who can see the video is the row most parents skip and the one that matters most for privacy; our post on where baby monitor video goes walks through it. When the vendor shuts down is not a theoretical row, as the section further down shows.

Where an app wins

An app wins on cost, range, updates and travel, and on privacy when it connects your two devices directly. In detail:

• Zero hardware cost. You use a phone or tablet you already own. The only extras are a stand and a charger.
• No distance limit. The parent unit of a radio monitor stops a few rooms away. An app works from the garden, the office or another city, as long as both devices are online.
• Software updates. A dedicated unit is finished the day it leaves the factory. An app gets new detection models, bug fixes and iOS compatibility fixes for as long as the developer maintains it.
• Privacy, when the app is device-to-device. Peer-to-peer means the video goes straight from one device to the other and no server stores it. A cloud camera cannot offer that; a radio monitor offers it by default. Our post on whether baby monitors can be hacked explains what to look for.
• Travel. The two devices already in your bag are the whole kit. Nothing else to pack, nothing to re-pair at a hotel.
• Alerts on the phone you already carry. No second gadget in your pocket. On iPhone the alert still has to get past Sleep Focus; our guide to alerts silenced on iPhone covers the settings.

Where a dedicated monitor wins

A dedicated radio monitor wins on independence from the internet, night vision, battery life and simplicity. In detail:

• No internet needed. A radio monitor works in a house with no broadband, during an outage, and in a holiday cottage with no Wi-Fi. An app on two phones cannot do that.
• Night vision. Almost every dedicated video unit has infrared LEDs that light the crib for the camera without lighting the room. Phone cameras do not, so an app shows a dark room as a dark room unless you leave a night light on.
• A parent unit with its own battery. The handheld screen runs all night on a charge and sits on the bedside table switched on. Nobody has to unlock a phone and open an app at 3 a.m.
• No phone tied up. The device at the crib is a purpose-built camera. Nobody needs to borrow it, and no update restarts it at midnight.
• Two-way talk and lullabies. Most dedicated units let you speak to your baby through the camera and play a few soothing sounds. Some apps have this; many do not.
• Nothing to configure. Plug in both halves and it works. No app to update, no notification permission to grant, no Focus mode to adjust.

A Wi-Fi camera with a cloud app sits between the two: it shares the app’s range and alerts and the radio monitor’s night vision, but it depends on the vendor and on the internet.

The middle ground: an app on a spare old phone

If you have an old iPhone in a drawer, you can get most of an app’s advantages without tying up your daily phone. The old phone becomes the camera at the crib and stays plugged in; your current phone is the screen. Apple lists iOS 16 as compatible with the iPhone 8, iPhone 8 Plus and iPhone SE (2nd generation) and every later model (Apple Support, 2022), so a phone from 2017 onwards usually qualifies.

What this fixes: the no phone tied up point in the dedicated column disappears, and the hardware cost stays at zero. What it does not fix: the old phone still needs internet and a charger, it still has no infrared, and it must stay unlocked with the app open. The full set-up, including power, heat and placement, is in our guide to using an old iPhone as a baby monitor.

Decision checklist

Pick the category that matches more of your lines below.

Pick an app if:

1. You already own two iPhones or iPads, or one plus an old one in a drawer.
2. You want to check on your baby from outside the home, or while travelling.
3. Your home internet is reliable, and both devices can stay plugged in.
4. You care about where the video goes and can choose a device-to-device app.
5. You are happy to leave a night light on, or you mainly want audio at night.

Pick a dedicated monitor if:

1. Your internet is unreliable, or the nursery is out of Wi-Fi reach.
2. You want to see the crib in a fully dark room.
3. You do not want a phone tied up at the crib or on the bedside table.
4. You want two-way talk or built-in soothing sounds.
5. Several adults share the night shift and a handheld unit passes between them more easily.

If you are torn, the spare-old-phone route above lets you try an app for the price of a stand.

Where Nanuka fits

Nanuka belongs in the first column. It turns two Apple devices you already own into a baby monitor. One device — the Baby Station — sits near the crib and streams live video and audio. The other — the Monitoring Station — is the one you keep with you. It runs on iPhone and iPad with iOS 16 or later. There is no extra hardware to buy, no account to create, and the video never passes through a server: the stream is encrypted and travels device-to-device, and no server stores it. Cry detection runs on the Baby Station itself, with no audio uploaded anywhere; the details are in our post on on-device cry detection. Alerts arrive as Time Sensitive notifications. There is no distance limit, and Picture in Picture keeps the feed on screen while you use other apps.

What you need: two Apple devices on iOS 16 or later, one as the Baby Station near the crib and one as the Monitoring Station with you, each with an internet connection. Pairing takes a QR code or a short code, with no account. Nanuka is on the App Store, and the set-up on a spare phone is in our guide to using an old iPhone as a baby monitor.
