Baby monitor for travel: what works in hotels, on planes and when camping

Which baby monitor works when you travel depends on where you stay. A non-Wi-Fi radio monitor needs no internet, but hotel walls and the devices next door work against it. A Wi-Fi camera often can’t get past the login page of hotel Wi-Fi. A baby monitor app on two phones has no radio range limit, but it needs internet on both. Whatever you take, test it before you leave the room.

Do you need a baby monitor when you travel?

Not always. If you all sleep in one hotel room and stay close by, you will usually hear your child yourself. A monitor earns its place once a door, a wall or a floor separates you: a holiday rental with a separate bedroom, a house with a terrace, a balcony with the door shut, or a suite with two rooms. The guide Do I need a baby monitor? covers the question for home.

Whatever the technology, the real limit is you. Switzerland’s Federal Office of Public Health (FOPH) reminds parents that it is their personal responsibility to move only so far away that they can return to their child as quickly as possible, and warns that systems working over a mobile network, the cloud or an extended Wi-Fi network can allow excessive distances. That applies to the hotel restaurant three floors down as much as to the beach.

Why do baby monitors stop working in hotels?

Three things get in the way:

• Walls and floors. According to the FOPH, radio connections can be disrupted by walls, ceilings, furniture and windows. Germany’s Federal Office for Radiation Protection (BfS) gives DECT as an example: up to 300 metres outdoors, but up to 50 metres inside buildings. Between a hotel room and the bar there are often several floors and corridors.
• Other monitors on the same channel. Consumer NZ, New Zealand’s consumer organisation, says monitors using common radio frequencies may pick up signals and interference from nearby devices, including the neighbours’ baby monitors. In a hotel, rooms share walls, and the family next door may be running a monitor too. Some monitors let you switch frequency, and Consumer NZ calls DECT monitors more private and less prone to interference. Why strangers can listen in on analogue monitors is explained in Can baby monitors be hacked?
• Hotel Wi-Fi with a login page. Many hotel networks only let a device online once you accept terms or enter a code on a web page, known as a captive portal. The Internet Engineering Task Force (IETF) notes that this typically requires a web browser. A phone has one; a Wi-Fi camera without a screen does not. And a camera set up on your home network has to be connected to the hotel’s network first.

Can you take a baby monitor in your carry-on?

Yes, and anything with a lithium battery – every phone and tablet included – belongs there. The US Federal Aviation Administration (FAA) says:

• Devices containing lithium batteries should be carried in carry-on baggage.
• If they go in checked baggage, they must be completely powered off and protected against accidental activation and damage.
• Spare lithium batteries are always prohibited in checked baggage. If your carry-on is checked at the gate, take them out and keep them with you in the cabin.

The UK Civil Aviation Authority (CAA) tells passengers in 2026 to take mobile phones and power banks on board, never to charge a power bank during a flight, and to check with their airline. In practice: the monitor, its chargers and your power bank go in your carry-on, which also means everything is to hand on the first evening. For a monitor app, you only pack the spare phone or tablet and its charger.

What to look for in a travel baby monitor

If you are choosing a monitor for trips, a few features matter more away from home than in your own house:

• Battery power on the baby unit. Consumer NZ points out that it helps where there is no mains power, for example when camping. A battery in the parent unit lets you carry it with you.
• Less interference. A choice of channels, or DECT, helps in a hotel full of other devices.
• No Wi-Fi needed where the network is unreliable. What to know about these devices is in Non-Wi-Fi baby monitors.
• Nothing extra at all, if you use an app on a phone or tablet you are taking anyway (see below).

How to set up a baby monitor in a hotel room or holiday rental

1. Choose the spot. The FOPH recommends placing the baby unit at least one metre from the cot and keeping its power adapter at least 50 cm away. That includes a travel cot.
2. Keep cords out of reach. The US Consumer Product Safety Commission (CPSC) urges parents to keep monitor cords at least three feet (about 90 cm) from any part of a crib, bassinet or play yard, and never to put a monitor inside or on the edge of a crib, because children can strangle in the cords. If the only socket is right by the bed, put the travel cot somewhere else.
3. Sort out power. Pack the adapter and cable, plus a travel adapter abroad. A device that has to run all evening should be plugged in.
4. Test the range on the first evening. The BfS advises checking the range yourself before use. Walk with the parent unit to everywhere you plan to be: the balcony, the terrace, the corridor, the room next door. Have someone talk quietly in the room; what matters is whether you would still hear soft crying.
5. On a radio monitor, check the channel. If you hear strangers or another child, switch channels if your monitor allows it.
6. On Wi-Fi or an app, get both devices online. Sign both in to the Wi-Fi, and check later in the evening that they are still connected. Where the Wi-Fi does not reach, check the mobile signal.
7. Charge the parent unit and turn it up. It stays with you all evening.

Baby monitors for camping and places without internet

At a campsite, in a mountain cabin or in a holiday house with no Wi-Fi and a weak mobile signal, a radio monitor is the more dependable choice: it only needs two units within range of each other. Without mains power at the tent, a baby unit that also runs on batteries helps. Neighbours’ devices can interfere here too, so test before you walk away.

Using a baby monitor app while travelling: what it needs

A baby monitor app turns a spare phone or tablet into the unit in your child’s room, and your own phone receives. On a trip, that means no extra monitor in your luggage and no radio limit between the room and the terrace. In return:

• Both devices need internet: the hotel’s or rental’s Wi-Fi, or mobile data. An old phone without a SIM card depends on the Wi-Fi.
• No internet, no monitor – not even with both devices in the same room. Where there is no network, take a radio monitor.
• Mobile data has limits. Live sound, and live video even more so, use up your data allowance. Abroad, roaming charges may apply; check with your carrier before you go.

How to set up a spare phone is explained in How to use an old phone as a baby monitor.

This is how Babyfino is built for it: the app works over any internet connection on both devices. In a hotel, you sign both devices in to the Wi-Fi as you would for any app, or use mobile data. Where a network blocks direct connections between the devices, sound and video go end-to-end encrypted through Babyfino’s relay, which can also be reached over port 443, the port secure websites use and that hotel and guest networks usually allow. That is how it is designed; it has not yet been shown on real devices in hotels. If the baby device loses its connection, for example because the Wi-Fi drops it, you are alerted about ten seconds later, and before it starts, Babyfino checks that alerts reach you.

If a babysitter looks after your child one evening on holiday, you invite them by QR code for that evening only: they hear the room live, receive the alerts, and their access ends with the evening by itself. Babyfino is coming soon for iPhone and Android.
