eufy: Smart Home Security and Backup Power for UK Households

eufy is a smart home brand, now part of Anker, that makes security cameras, video doorbells and home alarm kits for UK households. For anyone getting ready for a power cut, a storm or a break-in, the appeal is straightforward: a camera or alarm that keeps working when the mains goes off, tells you what is happening at home while you are out, and does not depend on a monthly subscription. eufy sells in the UK through anker.com/uk, and its products come with a 30-day money-back guarantee and a warranty on every order.

The kit that matters most for preparedness is the security range: the eufyCam S4, the eufyCam S3 Pro, the Eufy SoloCam S340 and the Eufy HomeBase S380. These are cameras and a hub that can run on their own batteries, so they carry on watching the house when the power fails. That is the point where a smart home stops being a convenience and starts being part of your emergency plan.

This page sets out what eufy makes, how long the batteries last, what the software and privacy commitments are, and how to get help. It does not rank eufy against other makers. It explains what the kit does for a household preparing for, or living through, a disruption, and where it fits alongside the rest of your home security arrangements.

eufy is now part of Anker: buying in the UK from anker.com/uk

eufy now sits within Anker, and UK orders are handled through anker.com/uk. For a household, that changes little about the kit itself but does change where you buy and who you deal with if something goes wrong. Buying direct from the maker, or from an authorised retailer, is the safest route. It means the device is genuine, it carries the warranty, and it will receive the software updates the maker promises.

That last point matters more than it sounds. The National Cyber Security Centre explains that under UK law the manufacturer must state the minimum length of time for which a smart device will receive important security updates⁵. A camera or alarm that stops getting updates becomes a weak point in your home network. Buying from a source that stands behind the product is how you keep that protection.

The fire and rescue services give the same advice for anything electrical: buy from reputable sellers that meet UK product safety standards and display the UKCA or CE safety mark⁶. That applies to smart home kit as much as to a washing machine. Online auction sites and unknown marketplace sellers are where unsafe or non-compliant electrical goods turn up, and a security device is not something to take a chance on.

What eufy makes for UK households

eufy's range for UK homes centres on security: cameras that watch the outside of the house, video doorbells, and alarm kits that cover doors, windows and movement. For an emergency preparedness site, the useful question is not what the kit does day to day but what it does when something goes wrong.

A power cut is the clearest test. Mains-powered cameras and doorbells go dark the moment the electricity fails. Battery-powered cameras and sensors keep working, which means you can still see what is happening outside, and your alarm still triggers if someone tries a door. That is why battery life and how the kit communicates matter more than resolution or app features for a household planning for disruption.

The 5-Piece Home Alarm Kit shows how the pieces fit together. It arms and disarms by keying in a password or from the phone through the eufy Security app, and it sends an instant notification when motion or a breach is detected¹. The keypad runs on batteries for 6 months, and the motion and contact sensors for 2 years¹. That is a long time between battery changes, but it is not indefinite, and a sensor with a flat battery is a gap in your coverage.

The kit is a one-time purchase with no monthly fees¹. For a household on a budget, that matters: there is no subscription to lapse during a hard month, and no service to cancel if you decide the kit is not for you. The trade-off is that you are responsible for changing batteries and installing updates yourself.

Security cameras that keep watching when the power goes

The cameras are the heart of eufy's offer to a household thinking about emergencies. The eufyCam S4 and eufyCam S3 Pro are the models to look at if you want a camera that runs on its own battery rather than the mains. The Eufy SoloCam S340 is a single camera for a specific spot, such as a driveway or back gate. The Eufy HomeBase S380 is the hub that ties them together.

Why does this matter for preparedness? Because the moments you most want to see your home are the moments when the power is most likely to be off. A storm that brings down a line, a flood that cuts the electricity, a planned outage for repairs: in each case a mains camera is blind. A battery camera is not. It also keeps recording if the broadband goes down, depending on how it stores footage, which is worth checking before you rely on it.

The trade-off is maintenance. Battery cameras need charging or new batteries, and a camera you have forgotten about is a camera that is not watching. Build a check into your routine: look at the app once a month, confirm each camera is online and charged, and clear any alerts. That habit is the same one you would apply to a smoke alarm or a torch.

Who eufy is: a smart home brand available in 59 countries

eufy describes itself as a smart home brand available in 59 countries⁷. That scale is worth knowing for one practical reason: a brand with a wide footprint is more likely to have a UK support operation, spare parts and a track record you can check. It also means the software and privacy commitments are made for a global market, so read the UK-specific terms on the Anker UK site.

For a household, the more useful question is whether the brand's priorities match yours. eufy's security products are built around keeping a record of events around the home and keeping that data private¹. The company says every eufy Security product is engineered to keep data private, and that the parts of the kit communicate with the HomeBase hub over a secure long-distance connection¹. Those are the maker's own claims, and they are the kind of thing to weigh alongside independent reviews.

The scale also means you are not buying into a tiny startup that might vanish. That matters for a device you intend to rely on for years. A camera that stops getting updates, or a hub that is no longer supported, is worse than no camera at all if you have built your household plan around it.

Warranty, returns and software updates

Three commitments decide whether a piece of kit is a long-term part of your plan: the warranty, the returns window, and how long the software is supported. eufy offers a warranty on every order and a 30-day money-back guarantee⁷. The software commitment is the one to read carefully.

Which found that eufy has said it will update its doorbells for at least five years from launch². That is a longer commitment than some makers offer, and it is the figure to hold the company to. Under UK law the manufacturer must also state the minimum period for which a device will receive important security updates⁵, so check the product page for the stated period before you buy.

Updates are not optional. The National Cyber Security Centre and the government's emergency alert guidance both stress keeping devices up to date⁵. An out-of-date camera is an easy way into your home network, and a compromised camera is worse than a switched-off one. Turn on automatic updates if the app offers them, and check for updates when you do your monthly battery check.

Privacy: TRUSTe certification and what it means at home

A security camera points at your home, your garden and possibly your neighbours' property. Privacy is not an abstract concern; it is about who can see the footage and where it is stored. eufy says every eufy Security product is engineered to keep data private and to keep a secure record of events around the home¹. The company also says the parts of the kit communicate with the HomeBase hub over an ultra-secure long-distance connection¹.

Those are maker claims, and they are the right things to check. Look for the privacy settings in the app, decide whether footage is stored locally on the HomeBase or in the cloud, and set a strong, unique password for your account. The same discipline you apply to your email applies here: a reused password on a camera account is a door left open.

For a household, the practical steps are simple. Use a unique password, turn on two-factor authentication if it is offered, keep the app and firmware updated, and review who has access to the account. If you move house, remove the devices from your account before you hand over the keys.

Getting help: live chat 7am to 7pm, seven days a week

eufy runs live chat from 7am to 7pm, seven days a week¹⁰. That includes weekends, which is when many households actually get round to setting up new kit or troubleshooting a camera that has gone offline. Have your order number and the device model ready before you start, and describe what you have already tried.

For anything urgent, deal with the immediate risk first. If a device is overheating, smoking or showing signs of a battery fault, stop using it, unplug it if it is safe to do so, and move it away from anything flammable.

If you need help with a eufy order, a warranty claim or a return, use the live chat or the Anker UK site. Keep a record of the conversation and any reference number. For a household building a preparedness plan, the support arrangements matter as much as the specifications: a camera you cannot get help with is a camera you cannot rely on.

Where eufy fits in a household emergency plan

eufy kit is not a substitute for the basics: water, torches, a battery radio, a first aid kit and a plan for where to meet. It is an addition, and it earns its place when it does something the basics cannot. A battery camera that keeps watching during a power cut, and an alarm that tells you when a door opens while you are away, are useful in a storm, a flood or a security incident.

The limits are just as important. The kit depends on batteries, on a working app and on a network connection for alerts. If the mobile network is down, notifications may not arrive. If the hub loses power and has no backup, footage may not be stored. Plan for those gaps: keep a torch and a battery radio as your fallback, and test the camera setup during a planned outage so you know what it does.

For the wider picture, see our guides to home security, power cuts and staying informed. Those pages cover the basics that any household needs, whatever kit it owns. eufy is one part of a plan, not the whole of it.
