eufy Security HomeBase 3 (HomeBase S380): The Hub That Ends Monthly Fees

The eufy Security HomeBase 3 is the brain that turns a collection of eufy cameras into a private, fee-free surveillance system. It is built for homeowners who already own or plan to buy eufy devices and want footage stored on a drive in their own house rather than on a subscription cloud. This review covers what the hub does, how its storage and AI features change day-to-day use, and where the hardware falls short so a buyer can decide quickly whether it belongs in the setup.

Features and Specifications

Type: Smart home hub and local storage base for eufy devices
Storage: Up to 16 TB expandable local storage
AI: BionicMind facial recognition
Security: Advanced encryption
Fees: No monthly fee
Compatibility: eufy Security devices

The headline number is the storage ceiling. A hub that accepts drives up to 16 TB gives a household room for weeks or months of continuous recording, depending on how many cameras feed it and at what resolution. That capacity is the reason buyers choose this unit over the small base stations bundled with camera kits.

The second pillar is BionicMind, eufy’s on-device facial recognition. The hub processes faces locally, which means the system can label familiar people and flag strangers without shipping biometric data to a server. Advanced encryption protects what sits on the drive, so a stolen hub does not hand over a household’s footage.

Build and Design

The HomeBase 3 is a desktop unit meant to sit near the router, and its job is to be boring: a black box that stays powered and connected. Buyers should plan for a wired Ethernet connection to the router and a free power outlet, because a hub handling multiple camera streams benefits from a stable wired link rather than Wi-Fi.

The design decision that matters most is the internal drive bay. The hub ships ready to record, but the expandable storage is the real feature — a buyer can fit a larger drive later as the camera count grows. That upgrade path keeps the hub useful for years instead of forcing a replacement when storage runs out.

Capacity and Storage

Storage is where this hub separates itself from the entry-level base stations that come in eufy camera bundles. Those small units hold a fixed amount of footage and cannot grow. The HomeBase 3 accepts drives up to 16 TB, so a household running several cameras can keep far more history on hand.

More history changes how the system gets used. A buyer can review events from weeks back, hand footage to police or an insurer without a cloud export, and keep recording through an internet outage. The trade-off is that all of that footage lives on one device in one place — a fire, flood or theft that takes the hub also takes the recordings unless the owner keeps a backup drive or a second copy elsewhere.

Power and Connectivity

The hub is a mains-powered device, not a battery unit, so it needs a permanent outlet and belongs on a shelf or desk near the router. That is normal for a base station and worth planning for before purchase: a buyer without an outlet near the router will need an extension cord.

Connectivity runs through the home network to the eufy cameras and doorbells. Because the hub does the recording and the AI processing, the cameras themselves can stay lean — they stream to the hub rather than relying on their own storage. The wired link to the router is the part that keeps multiple simultaneous streams smooth.

Maintenance and Everyday Use

Day-to-day, the hub runs unattended. The main maintenance task is managing the drive: checking free space as the camera count grows and swapping in a larger drive when needed. Buyers who add cameras over time should watch storage use rather than assume the original drive lasts forever.

The facial recognition needs a short setup period. The system learns faces as it records, and the owner confirms or corrects labels in the app. Accuracy improves with use, but a household with frequent visitors or a busy front door should expect some manual sorting in the early weeks.

Trade-off: The hub locks buyers into eufy’s ecosystem and puts every recording on a single device in the home, so it is the wrong pick for anyone who wants brand-mixed cameras or off-site backup by default.

Who It Suits and Who It Does Not

The HomeBase 3 suits the buyer who already runs eufy cameras or plans to build a system around them and wants to stop paying a monthly cloud bill. It also fits the household that values keeping footage in the house — renters in apartments, owners of small businesses, and anyone uneasy about biometric data leaving the home.

It does not suit a buyer with cameras from other brands, because the hub only manages eufy devices. It also falls short for anyone who wants automatic off-site backup without extra work, since local storage is the whole point and the recordings do not leave the house unless the owner copies them out.

FAQ

1. What does the eufy HomeBase 3 actually do?
   It records and stores footage from eufy cameras on a local drive, runs facial recognition on the device, and acts as the central hub that connects the cameras to the app.

2. Does the HomeBase 3 require a monthly fee?
   No. Local storage is the core feature, so there is no subscription needed to record and review footage. Cloud options may exist separately, but the hub works without them.

3. How much storage does the HomeBase 3 hold?
   It supports expandable local storage up to 16 TB, which is enough for weeks or months of footage depending on camera count and resolution.

4. Can the HomeBase 3 work with non-eufy cameras?
   No. It is built as a smart hub for eufy devices, so cameras from other brands will not connect to it.

5. What is BionicMind facial recognition?
   It is eufy’s on-device AI that learns faces and labels familiar people versus strangers, processing the data locally on the hub rather than in the cloud.

6. Is the HomeBase 3 hard to set up?
   Setup is app-guided and needs a wired connection to the router plus a power outlet. Most buyers can complete it without professional help.

7. Can a buyer upgrade the storage later?
   Yes. The hub is designed for expandable storage, so a larger drive can be fitted as the camera count grows.

8. What happens to recordings during an internet outage?
   Because footage is stored locally, recording continues through an outage. Remote app access is what stops working until the connection returns.

9. Does the HomeBase 3 work with eufy doorbells as well as cameras?
   It is built as a hub for eufy devices, and doorbells from the same ecosystem are the natural pairing alongside cameras.

10. Is the footage encrypted?
    Yes. Advanced encryption protects the data stored on the drive, so a stolen hub does not expose the household’s recordings.

Bottom Line

The eufy Security HomeBase 3 is the right purchase for a household already committed to eufy cameras that wants local storage, on-device facial recognition and no recurring bill. The 16 TB ceiling and the upgrade path keep it relevant as a system grows, and the encryption and local processing answer the privacy concerns that push buyers away from cloud subscriptions. Buyers with mixed-brand cameras or a hard requirement for automatic off-site backup should look elsewhere — for everyone else in the eufy ecosystem, this is the hub that makes the system worth owning.
