Quick Answer
Amazon's fall Prime event, Prime Big Deal Days, runs October 6–7, 2026, and eufy Security is among the brands already discounting cameras, video doorbells, smart locks and NVR systems ahead of it. Across the eufy Security fall Prime Day deals we could verify, markdowns run from roughly 20% to 45% depending on the model, and the "up to 43%" headline applies to select items rather than the whole catalogue. Every eufy camera records to local storage — microSD, a HomeBase hub or an NVR — so none of them requires a monthly cloud plan.
Key Takeaways
- Amazon's Prime Big Deal Days is set for Oct 6–7, 2026, and early eufy discounts were already live two weeks beforehand (Fox News and New York Post, accessed 2026-09-24).
- The deepest confirmed eufy cuts sit on camera kits and wired NVR gear: the 4K NVR Security System S4 Max was listed at $999.99, down from $1,499.99, roughly 33% off (per Popular Science, accessed 2026-09-24).
- eufy cameras write to a microSD card, a HomeBase hub or an NVR, so footage stays in your house and no subscription is needed to keep it (Tom's Guide, accessed 2026-09-24).
- The sale price is only half the cost story. Compare five-year totals with the calculator on this site before deciding a $99 camera is cheap.
- Deal prices move hour by hour during a Prime event, so treat every number below as a dated snapshot and re-check the product page before you check out.
When the fall eufy sale actually runs
Amazon's October event is officially called Prime Big Deal Days, and for 2026 it falls on October 6 and 7. Fox News reports that the sale opens at midnight Pacific on October 6 and that most — though not all — of the steepest discounts are reserved for Prime members. The New York Post, writing on September 21, 2026, confirms the same two-day window and notes that "early Prime deals" were already running a fortnight ahead of the main event.
That timing matters if you are buying security gear for a specific reason: a new rental, a move, or a house that will sit empty over the holidays. Waiting for the two-day window usually beats buying at full price, but the very best deals on individual models often surface in the early-access week and sell out before the official start.
eufy also runs its own promotional calendar in parallel with Amazon. Its published buying guides frame Prime Day as the early smart-home window and point to Black Friday in late November as the event with the widest catalogue-wide markdowns. Third-party sale trackers list a September "Fall Security Prep" period and a mid-to-late October Halloween promotion in Europe and Australia, so October is worth watching even if you miss the Amazon event entirely.
The eufy Security deals we could verify
The table below lists eufy discounts that a named outlet has published with a price. Some were reported during Amazon's summer Prime Day (June 23–26, 2026), which is the closest reliable baseline for what eufy discounts look like; fall pricing follows a similar pattern but is not identical. Every figure is a snapshot, and prices change daily during a sale.
| Product | Sale price | Typical price | Approx. discount | Source (accessed 2026-09-24) |
|---|---|---|---|---|
| eufy 4K NVR Security System S4 Max | $999.99 | $1,499.99 | ~33% | Popular Science; MacSources |
| eufyCam S4 4-Cam Kit (bullet + PTZ) | $949.99–$999.99 | $1,399.99 | 29–32% | Popular Science; MacSources |
| eufy Video Doorbell E340 | $99.99 | $149.99 | ~33% | Popular Science; MacSources |
| eufy SoloCam S340 (solar, 3K) | $109.99–$159.99 | $199.99 | 20–45% | MacSources; New York Post |
| eufyCam C37 4-Cam Kit | $249.99 | $449.99 | ~44% | Popular Science |
| eufy SoloCam E42 (solar 4K) | $113 | $179 | ~37% | Tom's Guide |
| eufy FamiLock S3 Max smart lock | $279.99 | $399.99 | ~30% | Popular Science; MacSources |
| eufyCam S3 Pro 2-Cam Kit | $399.99 | $549.99 | ~27% | Digital Camera World |
Two things stand out. First, the largest percentage cuts land on multi-camera kits, because that is where the list prices are highest and the margins are widest. Second, the wired PoE NVR Security System S4 Max is the only entry here that is a recorder rather than a camera, and it is the one most relevant to anyone who cares about storage.
Why local storage is the real discount
A eufy camera's sale price is a one-off cost; a cloud plan is a recurring one, and recurring costs are where security brands quietly make their money. Ring and Arlo both push subscription tiers for recording and playback, and reviewers routinely flag that as the main reason to look elsewhere.
eufy built its pitch on the opposite model. A HomeBase is eufy's local hub — the box that battery-powered cameras talk to — and it keeps recorded clips on hardware you own. Digital Camera World's reviewer notes the HomeBase supports up to 16TB of on-board storage and ships with 16GB to start, expandable, with HomeKit support for Apple households. Standalone cameras such as the SoloCam E42 hold up to 128GB on a microSD card, according to Tom's Guide, while the Video Doorbell E340 carries 8GB of built-in storage and can also pair with a HomeBase for more room.
That is the difference between a $99 doorbell and a $99 doorbell plus a monthly fee. If you want the longer version of that trade-off, our comparison of public cloud versus a private NAS walks through the ownership question in detail, and the same logic applies to camera footage.
NVR systems compared with a cloud camera plan
The cheapest way to own footage is not always the simplest, so it helps to compare the three common setups side by side.
| Approach | Upfront cost | Ongoing cost | Where footage lives |
|---|---|---|---|
| Battery camera + HomeBase | Low to mid | None required | Local hard drive in your home |
| PoE NVR system (e.g. S4 Max) | High | None required | Local NVR drive, continuous recording |
| Cloud camera plan | Low | Monthly, per camera | Vendor servers |
A PoE NVR trades convenience for certainty. One Ethernet cable carries both power and video, so a camera cannot go offline because it forgot to charge, and recording is continuous rather than motion-triggered. The trade-off is installation: you run cable, and you need a place to put the recorder. For renters and anyone in a quick setup, a HomeBase kit is the pragmatic choice; for a house you own and intend to keep, an NVR is the more durable one.
What to Look For
Storage and retention. The two questions that decide everything are how much space you need and how many days you want to keep. A single 4K camera recording continuously can fill a terabyte in a few weeks, which is why NVR systems ship with bays for multiple drives. Match the drive size to the retention window you actually want, not to the largest drive on sale.
Power and wiring. Battery and solar cameras are quick to install but depend on sunlight and charge cycles. Wired PoE cameras never need charging but require a cable run to each mount. Decide which constraint you can live with before you chase a discount.
App and ecosystem. Every eufy camera is controlled through the eufy Security app, and the HomeBase line works with Apple HomeKit and the major voice assistants. Check that the models on sale support the platform you already use — a discounted camera that fights your smart home is not a bargain.
Recommended setups for a storage-first home
Budget: one doorbell, one camera. A Video Doorbell E340 at around $99.99 plus a SoloCam S340 covers the two spots that matter most, the front door and the driveway. Both record locally, so there is no monthly bill.
Family: a HomeBase kit. A multi-camera kit with a HomeBase hub gives you central storage, one app, and room to add cameras later. This is the setup most households should default to.
Whole-home: PoE NVR. If you are wiring a property, the NVR Security System S4 Max records continuously from every camera onto local drives. Pair it with a NAS for off-camera backup and you have a full local-first pipeline.
Common mistakes with Prime Day camera deals
The first mistake is buying on percentage alone. A 45% cut on a camera you do not need is still money spent, and a 25% cut on the model that actually fits your house is the better deal. Decide on the model family first, then watch its price.
The second is forgetting the storage. A camera kit without enough local storage to hold your retention window forces you into either a subscription or a new drive, and that erases the discount. Price the storage in from the start.
The third is assuming "no subscription" means "no cloud at all". Most local-first cameras still offer an optional cloud tier; the point is that it is optional. Read the spec sheet rather than the banner, and check whether continuous recording — not just motion clips — is available locally.
Frequently Asked Questions
Do eufy cameras need a subscription?
No. eufy cameras record to local storage — a microSD card, a HomeBase hub or an NVR — and continue to record and play back without any monthly plan, according to Tom's Guide (accessed 2026-09-24). Cloud storage is offered as an optional extra, not a requirement.
How long do these eufy deals last?
Prime Big Deal Days itself runs two days, October 6–7, 2026, per Fox News. Individual model discounts can appear earlier in the early-access week and can sell out before the event opens, so the practical answer is to buy when the price you have been tracking appears, not to wait for a specific date.
Can I record eufy footage to a NAS instead of a HomeBase?
Not directly through the eufy app for most consumer models; the supported paths are microSD, HomeBase and NVR. A NAS is best used alongside them as your own backup and archive tier. If you want a NAS that handles surveillance storage well, see our guide to the best private cloud NAS.
Is an NVR better than a cloud camera plan?
It depends on the property, not the price. An NVR gives you continuous local recording with no monthly fee but needs cabling and a place to live. A cloud plan is faster to set up but adds a recurring cost and keeps your footage on someone else's servers. For most people who own their home, the NVR wins on total cost after two to three years.
