Smart speakers, cameras, plugs, doorbells and televisions can make everyday tasks easier, but every connected device adds another account, app and update routine. This Fapeza guide explains how to protect smart home devices in the UK with practical steps that do not require advanced networking knowledge.
Device menus vary by manufacturer. Use the latest official instructions for your exact model, especially when changing security or privacy settings.
Make a simple device inventory
List each smart device, the account that controls it, the app it uses and whether it is still supported. Include products that are easy to forget, such as old streaming sticks, printers, cameras and plugs. An inventory helps you notice devices that have not received an update or are still linked to a previous owner.
Remove products you no longer use from the app and reset them before selling or giving them away. If a device cannot be reset or supported, consider replacing it rather than leaving it permanently connected.
Change default passwords and use two-step verification
Use a unique password for every important device account. Do not reuse your email password for a camera or smart-home app. Turn on two-step verification when the manufacturer offers it, and keep recovery details current.
The National Cyber Security Centre’s smart-device guidance explains why default credentials and unpatched products create avoidable risk. Start with your email account because access to it may allow someone to reset other accounts.
Update the device, app and router
- Install firmware and app updates from the official manufacturer or app store.
- Enable automatic updates if you understand what will change and the option is trustworthy.
- Replace products that no longer receive security updates where practical.
- Keep the router updated and use a modern Wi-Fi security setting.
- Remove old integrations that are no longer needed.
Put update checks into a monthly reminder. A device that worked perfectly when installed may become less secure if its software stops receiving fixes.
Limit permissions and account sharing
Review what each app can access. A smart light may not need your contacts, location history or microphone. Use the least access needed for the feature you actually use. If several people need control, use the platform’s household or guest-sharing feature rather than sharing one password by text.
For cameras and microphones, think about where the device points, when it records and who can view it. Keep indoor cameras away from private areas and tell visitors when recording may occur. Check storage, notifications and deletion controls.
Use safer network habits
Follow the steps in Fapeza’s home Wi-Fi checklist: use a strong router password, update firmware, disable unnecessary remote administration and consider a guest network. A separate network can reduce exposure for lower-trust devices when the router properly isolates it.
Do not expose a device’s administration page directly to the public internet unless you understand the security implications and have a specific need. If a product insists on an unusual connection method, read the provider’s documentation before enabling it.
Check privacy before buying
- Read what data the device collects and whether it uses cloud storage.
- Check where recordings or account information are processed.
- Look for an update-support statement and the manufacturer’s contact details.
- Review subscription terms for features you expect to be included.
- Consider whether the convenience is worth the data and maintenance required.
Do not buy a device only because it has the most features. A simpler product from a transparent provider may be easier to secure and maintain.
Smart-home security FAQ
Should smart devices use the guest Wi-Fi network?
It can help, but isolation differs by router. Check the router’s documentation, keep the device updated and do not assume every guest network blocks every form of access.
How often should I check smart-home settings?
Review devices when you install them, after a major app update and at least a few times a year. Monthly update reminders are useful for products you rely on.
What should I do with an unsupported device?
Disconnect it from the network, remove it from the account and follow the manufacturer’s reset or recycling instructions. Replace it when the security risk outweighs its usefulness.
What to do if a device behaves strangely
Unexpected behaviour does not always mean an attack: an update, weak connection or failing battery can create similar symptoms. Start by checking the manufacturer’s support page and recent notifications. If the device repeatedly connects to an unknown account, records unexpectedly or cannot be controlled, disconnect it from the network and contact the provider from a trusted device.
Change the relevant account password, enable two-step verification and review recent sign-ins. Do not factory-reset a device if you need its settings or evidence for a support request until you have recorded what happened. Once the issue is understood, update the device or replace it if it is no longer supported.
Agree simple household rules
- Only install smart-home apps from official stores.
- Tell household members when a camera or microphone is active.
- Do not share account passwords through group chats.
- Ask before connecting a new device to the main network.
- Remove access when someone no longer lives in the home.
These rules are especially useful when visitors, children or short-term tenants use connected equipment. Security is easier when everyone understands the same basic expectations.
