5 Best HomeBase 3 Accessories for a Better Setup
Best HomeBase 3 Accessories: Upgrade Your S380 the Right Way
Buying a eufy HomeBase 3 (S380) is only the beginning. Once more cameras start recording people, vehicles, deliveries, and activity around your home, storage becomes one of the easiest parts of the system to overlook.
The problem usually appears later: recordings accumulate, older footage becomes more important than expected, and you realize that choosing the wrong storage drive or accessory can mean wasted money, limited capacity, or hardware that does not work properly with your HomeBase.
Your HomeBase 3 is powerful — but the wrong upgrade can hold it back
HomeBase 3 comes with 16GB of built-in local storage. That may be enough to get started, but homeowners running multiple cameras, frequent motion recording, or longer video retention can quickly benefit from expanding beyond the included capacity.
eufy allows the S380 to accept a 2.5-inch SATA HDD or SSD up to 16TB, giving you the option to dramatically increase how much security footage can be stored locally. The important part is choosing a drive with the correct size, interface, capacity, and power requirements.
That is why this guide focuses on accessories that actually improve the HomeBase 3 experience — especially storage upgrades that can give your security system more recording capacity without forcing you into unnecessary monthly cloud storage.
We will compare the strongest HomeBase 3 storage options, explain which capacity makes sense for different camera setups, and show you which accessories are worth buying — and which ones you can safely skip.
Best HomeBase 3 (S380) Accessories & Upgrades Compared
The right upgrade depends on what is limiting your eufy setup today. Some owners simply need a cleaner place for their HomeBase, while others need centralized local storage, an easier way to monitor several cameras, or a more powerful hub for a growing security system. Compare the options below by the problem they solve rather than choosing the most expensive one.

Our Top Pick: eufy Security HomeBase 3 (S380)
If you want one upgrade that changes what your compatible eufy cameras can do as a system, HomeBase 3 (S380) is our strongest recommendation. A wall mount improves organization and a dedicated display improves convenience, but the S380 addresses the foundation: centralized local storage, expandable capacity, and additional smart-security capabilities for supported eufy devices.
Why HomeBase 3 Is the Upgrade We Would Prioritize First
Security systems tend to grow gradually. You start with one camera, add another near the driveway, then protect the backyard or garage. At that point, the bigger problem is no longer choosing another camera—it is deciding where all those recordings should live and how the devices should work together.
If you are still choosing the cameras that will sit behind your HomeBase 3 setup, our eufyCam S3 Pro vs S330 comparison breaks down which 4K solar model makes more sense for premium performance versus overall value.
That is where HomeBase 3 earns its place. The S380 provides 16GB of built-in storage and includes an internal bay for a compatible 2.5-inch SATA HDD or SSD, with expansion up to 16TB. Instead of treating storage as a fixed limitation, you can increase capacity as your camera system and recording needs grow.
- Expandable local storage: Install a compatible 2.5-inch SATA HDD or SSD and expand storage up to 16TB.
- Built for a growing eufy system: Centralizing compatible cameras becomes increasingly useful as you protect more areas around the property.
- BionicMind intelligence: Supported devices can benefit from additional AI capabilities such as familiar-face recognition and more meaningful event identification.
- Less dependence on cloud recording: Local recording gives compatible setups a practical path to storing footage without making a monthly cloud-storage subscription mandatory.
- Upgrade when you actually need it: You do not have to pay for maximum storage on day one. Start with the included capacity and add a compatible drive when your recording requirements justify it.
Should You Buy the Professional S1 Instead?
Not automatically. The HomeBase Professional S1 is more appropriate for buyers with heavier recording demands who can genuinely benefit from its larger out-of-box storage and more advanced system positioning. Paying for that level of hardware simply because it is the premium option can be unnecessary for a typical household.
For many eufy owners, the smarter progression is to begin with HomeBase 3 and expand its storage when needed. That keeps the initial investment more controlled while still leaving substantial room for the system to grow.
Who Should Choose HomeBase 3?
We recommend the S380 most strongly to homeowners who already own—or plan to build—a compatible multi-camera eufy system and want more control over long-term storage. It makes considerably more sense when you are building a security ecosystem than when you only need a simple accessory for one standalone camera.
Koroao HomeBase 3 Wall Mount
A simple, low-cost upgrade for HomeBase 3 owners who want to get the hub off a crowded desk or shelf and create a cleaner, more permanent setup.
Best when the problem is placement—not performance
Not every useful HomeBase 3 upgrade needs electronics inside it. If your S380 is sitting beside a router, switch, modem, or other smart-home hubs, the Koroao HomeBase 3 Wall Mount solves a much simpler problem: finding a dedicated place for the HomeBase without sacrificing valuable shelf or desk space.
The holder is shaped specifically around the eufy Security HomeBase 3 (S380). Instead of placing the hub on a generic shelf, you can secure it to an appropriate indoor wall and keep the HomeBase in a fixed location.
If your eufy system has grown beyond the capacity that individual microSD cards can comfortably provide, you can also upgrade HomeBase 3 with an HDD or SSD and move toward much larger centralized local storage for compatible cameras.
Why This Small Accessory Can Make a Big Difference
A security hub is normally installed once and then left running for long periods. That makes it a good candidate for wall mounting. Moving it off a work surface can reduce clutter and help separate the HomeBase from the collection of chargers, cables, routers, and other equipment that tends to accumulate around a home network.
- Made for HomeBase 3: The holder is designed around the S380 rather than functioning as a generic wall shelf.
- Recovers useful surface space: A practical choice when your router shelf, cabinet, or desk is already crowded with networking and smart-home equipment.
- Creates a permanent HomeBase location: Keeps the hub from being repeatedly moved when cleaning or reorganizing nearby equipment.
- Cable-conscious design: The holder provides space for routing the HomeBase connection rather than simply trapping the unit against a wall.
- No software or configuration: There is nothing to pair, charge, update, or configure after the physical installation.
What You Give Up Compared With Our Top Pick
This is where the distinction matters. The Koroao mount improves the physical installation, but it does not improve the capabilities of the security system itself.
It adds no recording capacity, AI processing, backup power, camera support, or new security features. If your real problem is limited storage or the need to centralize compatible eufy cameras, purchasing HomeBase 3 (S380) itself—or expanding its storage—is a much more meaningful upgrade.
Who Should Buy the Koroao Wall Mount?
It makes the most sense for someone who already owns HomeBase 3 and wants a cleaner installation. It is particularly useful around compact router shelves, home offices, equipment areas, and other places where horizontal space is limited.
If your S380 is already sitting safely in a convenient location with plenty of space, however, this is an accessory you can comfortably skip and put the budget toward storage or another functional upgrade instead.

eufy HomeBase Professional S1
Which HomeBase 3 Upgrade Should You Actually Buy?
The best purchase is not automatically the most expensive one. Start with the limitation you are trying to fix. A homeowner who needs more storage has a very different problem from someone who wants easier camera viewing or simply needs to get a HomeBase off a crowded shelf.
Match the Upgrade to Your Actual Setup
- Building a compatible eufy security system from the ground up? Choose the eufy Security HomeBase 3 (S380). It is our top recommendation because it gives the system a central foundation for local storage, expandable capacity, and supported BionicMind features.
- Already own HomeBase 3 but hate where it sits? Choose the Koroao HomeBase 3 Wall Mount. It is the inexpensive solution when organization and shelf space are the problem—not storage or security performance.
- Have several cameras and constantly reach for your phone to check them? Consider the HomeBase 3 + Smart Display E10 setup. The dedicated display makes more sense for households that want security activity visible from a central screen instead of depending entirely on smartphone monitoring.
- Running a larger system with much heavier recording demands? Consider the eufy HomeBase Professional S1. Its higher-end positioning and large included storage are easier to justify when your setup genuinely requires more serious recording infrastructure.+++
Already Have an S380? Do Not Buy Another Hub Just for More Storage
This is one of the easiest ways to overspend. If your current HomeBase 3 works well and storage capacity is the only limitation, replacing the entire hub may solve a problem you could address much more cheaply.
HomeBase 3 supports a compatible 2.5-inch SATA HDD or SSD and can be expanded up to 16TB. For many existing owners, adding the right drive is therefore a more logical next purchase than replacing the S380.
Use This 30-Second Buying Rule
Think about what you would notice immediately after spending the money. If you cannot identify a meaningful improvement, you probably do not need that upgrade yet.
- Need the central hub? → HomeBase 3 S380
- Need more recording capacity? → Expand your existing S380 storage
- Need a cleaner installation? → Koroao Wall Mount
- Need faster, easier camera viewing? → Smart Display E10 setup
- Need a more demanding recording platform? → HomeBase Professional S1
Why Waiting to Upgrade Your HomeBase 3 Can Cost You Later
The best time to improve a security system is while everything is working normally—not after you discover that the footage, storage capacity, or setup you needed was not ready. If you already know what is limiting your eufy system, fixing that limitation now gives you time to configure and test the upgrade before you actually depend on it.
Security Storage Becomes Valuable Before You Know Which Recording You Will Need
Most recordings will never become important. The problem is that you cannot predict which one will. A package dispute, damaged vehicle, unexpected visitor, or activity around an entrance can suddenly make older footage much more valuable than it seemed when it was recorded.
That is why storage planning matters. If your compatible camera system is growing, HomeBase 3 (S380) gives you a path from its built-in storage to a compatible 2.5-inch SATA HDD or SSD with expansion up to 16TB. You can build capacity around your actual recording needs rather than waiting until storage becomes the problem.
Three Reasons to Complete the Upgrade Before You Need It
- You can test everything under normal conditions. Confirm camera compatibility, recording behavior, storage, notifications, and connectivity while there is no pressure to recover an important event.
- Your system can grow without forcing a rushed decision. Adding more compatible cameras can increase storage demands. Building around HomeBase 3 now gives you an expandable foundation instead of solving each new limitation separately.
- You avoid buying the wrong solution in a hurry. A storage problem may require a compatible drive, a viewing problem may call for the Smart Display E10, and a placement problem may only need a wall mount. Knowing the difference can prevent an unnecessarily expensive upgrade.
Do Not Upgrade Just Because Something Is on Sale
A discount does not make an unnecessary accessory useful. Existing HomeBase 3 owners who only need more capacity may be better served by adding compatible storage, while someone building a new compatible eufy system may get much greater value from the S380 itself.
Once you have confirmed that HomeBase 3 is compatible with the devices and features you intend to use, however, delaying the purchase solely to chase an unknown future price can leave the actual security upgrade unfinished.
Final Verdict: Build Your eufy System Around HomeBase 3
After comparing the upgrades in this guide, the eufy Security HomeBase 3 (S380) remains our strongest choice for most buyers building a compatible eufy security system. It solves a more important problem than simply adding another accessory: it gives your cameras a central foundation for local storage, system expansion, and supported BionicMind features.
Its biggest long-term advantage is flexibility. You can start with the included storage and, as your camera system grows, install a compatible 2.5-inch SATA HDD or SSD and expand capacity up to 16TB. That means you do not have to predict today exactly how much recording space you will need several cameras from now.
Our Recommendation Is Simple
- Starting or expanding a compatible eufy system? Choose HomeBase 3 (S380) as the core of the setup.
- Already own an S380 and only need more recording space? Keep your HomeBase and invest in compatible storage instead of unnecessarily replacing the entire hub.
- Want your HomeBase off the desk or router shelf? Add the Koroao HomeBase 3 Wall Mount for a cleaner installation.
- Want a dedicated screen for checking compatible cameras? Consider the Smart Display E10 setup for easier at-a-glance monitoring.
- Running a much heavier multi-camera recording system? The HomeBase Professional S1 is the more specialized option worth considering.
Ready to Upgrade Your eufy Security Setup?
If the S380 supports your current or planned devices, there is little reason to make your security setup more complicated than necessary. Start with the hub that fits the system you are building, then spend additional money only on the storage and accessories that solve a real need.
Frequently Asked Questions About HomeBase 3 (S380)
What does eufy HomeBase 3 actually do?
HomeBase 3 (S380) acts as a central hub for compatible eufy Security devices. It provides local video storage, supports expandable storage, and adds BionicMind-powered features to supported cameras. Its value becomes greater as you add more compatible cameras and want to manage them as one security system.
How much storage does HomeBase 3 include?
HomeBase 3 includes 16GB of built-in eMMC storage. For lighter event-based recording this gives you storage out of the box, but households with several cameras or heavier recording requirements may benefit from installing a larger internal drive.
Can you expand the storage on HomeBase 3?
Yes. One of the S380's biggest advantages is expandable local storage. HomeBase 3 accepts a compatible 2.5-inch SATA HDD or SSD and supports capacities up to 16TB. This allows the storage system to grow alongside your camera setup.
Can I use any HDD or SSD with HomeBase 3?
No. Do not purchase a drive based on capacity alone. HomeBase 3 requires a compatible 2.5-inch SATA HDD or SSD, and the drive must meet the S380's power requirements. In particular, drives requiring a 12V supply are not supported. Check the drive specifications before ordering.
Is an SSD or HDD better for HomeBase 3?
Both can make sense. An SSD has no moving parts and operates silently, while a compatible HDD can often provide more storage per dollar. If your priority is maximizing recording capacity economically, an HDD can be attractive. If you prefer solid-state storage and do not need maximum capacity for the lowest cost, an SSD may be the better fit.
Does HomeBase 3 require a monthly subscription?
A mandatory monthly cloud-storage subscription is not required to use compatible local recording with HomeBase 3. Optional services may still be available, so buyers should distinguish between the S380's local-storage capabilities and any additional paid eufy services they may choose to use.
What is BionicMind on HomeBase 3?
BionicMind is eufy's local AI system for HomeBase 3. With supported devices it can provide capabilities such as facial recognition and smarter identification of security events. Feature availability depends on the camera or device connected to the S380.
Does every eufy camera work with HomeBase 3?
No. Compatibility and available features vary between eufy products. A camera being sold under the eufy Security brand does not automatically guarantee access to every HomeBase 3 feature. Check your exact camera or doorbell model before buying the S380 for a specific storage, AI, or recording capability.
Is the Koroao HomeBase 3 wall mount worth buying?
It can be worthwhile if your S380 is taking up valuable desk, shelf, or networking space. The wall mount gives HomeBase 3 a dedicated location and can make the installation cleaner. It does not add storage, improve AI, or increase camera performance, so owners who already have a good location for their HomeBase can safely prioritize other upgrades.
Is the Smart Display E10 worth adding to HomeBase 3?
The Smart Display E10 makes the most sense for multi-camera households that want a dedicated screen for viewing compatible security devices. It can reduce the need to reach for a phone every time you want to check camera activity. For a small one-camera setup, however, the additional display may be harder to justify.
Should I upgrade from HomeBase 3 to HomeBase Professional S1?
Not necessarily. HomeBase 3 remains the more sensible choice for many residential eufy systems, especially when adding compatible storage solves the main limitation. HomeBase Professional S1 is better suited to buyers with heavier recording demands, larger systems, or requirements that justify a more advanced security hub.
What is the best HomeBase 3 upgrade to buy first?
Start with the problem you actually need to solve. If storage is becoming limited, prioritize a compatible HDD or SSD. If your HomeBase is cluttering a shelf, consider a wall mount. If checking multiple cameras on a phone is inconvenient, a dedicated display may provide more value. For someone who does not yet own the hub, HomeBase 3 (S380) is our top overall starting point for building a compatible eufy security system.
