Smart speakers, doorbell cameras, and connected appliances have become common in UK homes — and each one is a small computer connected to your network, which means each one is a potential point of weakness if not set up securely.
Change default passwords immediately on every device — many smart devices ship with a default password that's publicly documented online.
Keep device firmware updated via the manufacturer's app — security patches for known vulnerabilities are released regularly.
Use a separate guest or IoT network for smart devices, isolating them from computers and phones that hold more sensitive data.
Review camera and microphone permissions periodically, and disable always-listening features you don't actually use.
Check the manufacturer's privacy policy before buying, particularly for cameras and microphones — understand what data is collected and where it's stored.
These devices raise particular privacy considerations since they often record neighbours and passers-by as well as your own property. Position cameras to minimise capturing areas beyond your own property where practical, and be aware of your responsibilities under UK data protection law if your camera captures public or neighbouring spaces.
If you suspect a smart device has been compromised, disconnect it, perform a factory reset, and reconfigure it with a new, strong password before reconnecting it to your network.
