Can neighbours hear an analogue baby monitor in the UK?
What does 'analogue' mean on a hand-me-down monitor?
An analogue baby monitor is a small radio link. The baby unit sends sound on one of a short list of shared channels. The parent unit is a receiver tuned to that channel. There is usually no pairing ceremony and no per-household code. If two flats pick the same channel, both parent units can hear both rooms. That is why terrace and purpose-built-flat households still report hearing the baby next door — or being told their own audio is in someone else's kitchen.
Look at the label and the manual, not the box art. Words such as 49 MHz, channel A/B, or a slide switch with two or three numbers are typical analogue clues. Words such as DECT, digital, FHSS, paired, or a registration / pairing button describe a different design.
This page explains pairing so you can tell the designs apart. It does not explain how to tune in to a neighbour. Ofcom's spectrum pages, and section 48 of the Wireless Telegraphy Act 2006, treat intentional interception of a message you were not meant to receive as a criminal offence.
How is pairing different from picking a channel?

| Design | How the two boxes know each other | What a neighbour's matching handset can do |
|---|---|---|
| Analogue, shared channel | You (or the factory) pick channel 1, 2 or 3. Any receiver on that channel in range can open the audio | Hear the same channel — including yours — without your consent |
| DECT (digital cordless) | Baby and parent register to each other, as a home cordless phone does, on the European DECT band | Another DECT handset from the shop shelf does not automatically decode your pair |
| FHSS digital video / audio | The pair hop frequencies together after a registration step, often on 2.4 GHz | An unpaired screen is not meant to lock to your camera |
| Open Wi-Fi camera (Which? Liv Cam example) | The camera itself offered an open wireless network | Which? reported a nearby person could join that network; researchers also retrieved the camera password. App last updated September 2016; Summer Infant stopped selling the Liv Cam in early 2020 |
What should I do if I can hear the neighbours' baby?
- Stop treating it as entertainment Turn your parent unit down or off. You are not the intended recipient. Do not scan channels 'to see who else is on'.
- Read your own label If you have a channel switch, you are probably on analogue. Try the other marked channel so you are not sat on the same one. If every channel still carries someone else's room, the design is the problem, not the slider.
- Tell the neighbour without blaming them They may not know their baby unit is still transmitting after they switched the parent unit off. A polite note is enough. Do not retell what you heard.
- Move to a paired digital set if you stay with radio DECT audio or a registered FHSS video pair removes the shared-channel habit. That is a design change, not a finding that digital radio is fine in every terrace.
- If the 'neighbour' is actually an open Wi-Fi camera That is the Liv Cam-style problem: a camera network with no password. Factory-reset, set a unique password, or stop using that camera. See NCSC's camera steps — change defaults, update, disable remote view if you do not need it.
What if the neighbours say they can hear us?
Believe the report. Power the baby unit off (not only the parent unit — analogue transmitters often keep sending). Check you have not left talk-back or a lullaby loop on. If the set is analogue, treat it as a shared-channel radio and retire it rather than 'turning the volume down' on a link you cannot fence.
If the set is already DECT or FHSS and someone still hears nursery audio, look for a second parent unit you forgot about, a guest still signed into a Wi-Fi app, or a camera with an open network. Revoke app guests on the share-and-revoke page. Do not start hunting for other people's receivers.
Does hearing a neighbour change safer-sleep advice?
No. Crossover is a radio-design problem. The Lullaby Trust's position is unchanged: a monitor is not a substitute for a parent or carer; same room for the first six months; clear, flat, firm sleep space. Privacy of the link and safety of the sleep space are different questions.
In shortIn short: analogue means shared channel, not a private pair. If you hear them — or they hear you — power down, change channel once, then move to a paired DECT or FHSS set. Ofcom's rule is about not listening in. Which?'s Liv Cam notes are about an open Wi-Fi network, which is a modern version of the same 'anyone nearby can join' idea.
Questions parents ask
- Is it illegal if my analogue monitor crosses into next door by accident?
- Ofcom's offence is about using apparatus with intent to obtain a message you were not meant to receive, or disclosing it. Accidental crossover is why these sets are a poor fit for terraces; it is not the same as tuning a scanner on purpose. Do not keep listening once you realise it is not your baby.
- Does 'digital' on the box always mean the units are paired?
- No. Read for pairing, registration or DECT/FHSS. Some older 'digital' marketing still sat on a small set of channels. If you can slide a channel switch without ever pressing a pair button, treat it as shared-channel until the manual says otherwise.
- Can a Wi-Fi monitor have the same neighbour problem?
- A different mechanism, same neighbourhood. Which? found the Liv Cam used an open Wi-Fi network, so a nearby person could join, and researchers retrieved the camera password. That is why PSTI now bars shared default passwords on new connectable products — and why guest-app access still needs revoking.
- Should I put foil on the baby unit or turn the power down?
- Do not modify the radio or wrap it. You can make interference worse or overheat the adapter. The practical fixes are: other marked channel, then a paired digital set, then stopping use of an open-network camera.
