Save $405 on the eufyCam S4 Four-Camera Kit

The eufyCam S4 4-Cam Kit with the Smart Display E10 is down to $1,194.98 at Best Buy. That is a $405 cut from its listed comparable value of $1,599.98. For that price, you get four triple-lens outdoor cameras, a local storage hub, and a dedicated screen. There are no monthly fees attached.

What Is Inside the eufyCam S4 Bundle

This is a complete whole-home kit, not just a camera pack. Here is what comes in the box:

• Four eufyCam S4 cameras, each with its own detachable solar panel
• HomeBase S380, the indoor hub that stores your footage and runs the AI features
• Smart Display E10, a screen that shows your cameras and daily security summaries

Best Buy is running this as a limited-time deal, and the listing is sold and shipped by AnkerDirect. For comparison, eufy’s own US store lists this exact bundle at $1,649.98.

Why This Deal Is Worth a Look

The biggest selling point is zero subscription costs. Many camera systems charge a yearly fee to save your video clips in the cloud. The eufyCam S4 does not need one, although eufy notes that some optional premium features may require a subscription.

All footage is saved on the HomeBase S380, which has 16GB of built-in storage. You can expand that up to 16TB by adding any 2.5-inch drive. According to eufy, live viewing, recording, AI detection, and alerts all work without paying a monthly fee. Because the hub sits inside your house, a stolen camera does not take your recordings with it. That is a big part of why local storage beats cloud fees.

It is also a DIY system. The cameras mount with the included hardware, so professional installation is not required.

How the Triple-Lens Camera Works

Think of each camera as two security guards sharing one post. One guard stands still and watches the whole yard. The other walks over to get a closer look whenever something moves.

In technical terms, here is how that plays out:

• The top lens is a fixed 4K camera with a 130-degree wide view.
• The bottom lens is a 2K dual-lens camera that pans, tilts, and zooms (often called PTZ).
• Tracking kicks in automatically. Once the wide lens spots someone, the moving lens locks on and follows them.
• Zoom reaches far. Eufy says it can capture details up to 164 feet away, with up to 8X zoom.
• Night footage stays in color thanks to four built-in LED spotlights, so faces are easier to identify after dark.

If more people walk into view, the camera zooms back out to keep everyone in the frame.

Smarter Alerts With the Smart Display E10

Paired with the HomeBase S380, the cameras use eufy’s BionicMind AI. It can tell family members apart from strangers. It also detects people, vehicles, and pets.

The Smart Display E10 takes that information one step further. Using facial and package recognition, it builds daily summaries with stats and video clips. Instead of scrolling through dozens of recordings, you get a quick overview of what actually happened.

Solar Power and 24/7 Recording

Each camera uses a 5.5W solar panel. Eufy states that just one hour of direct sunlight a day keeps a camera running. The panel is detachable, which gives you more freedom when choosing a mounting spot.

There is one important detail here. Solar power alone gives you motion-triggered recording, not continuous recording. To unlock 24/7 recording, you need three things:

1. The included 14-foot cable kit
2. Your own 5V/2A (or higher) power adapter
3. Camera firmware V1.0.5.4 or later, HomeBase S380 firmware V3.7.2.8 or later, and the latest eufy app

The cameras also carry an IP65 rating, so rain, snow, and dust are not a problem.

Setup and Compatibility Notes

A few details are worth checking before you buy:

• 2.4GHz Wi-Fi only. The cameras do not support 5GHz. That is actually common for outdoor gear, since 2.4GHz travels farther through walls (like a bass note carrying through an apartment building).
• Works with Alexa and Google Assistant. In the Google Home app, you can view live feeds on Nest Hub and Chromecast devices.
• No Apple Home support. Eufy lists Apple HomeKit as not currently supported, so iPhone owners will need to use the eufy app instead.
• Check your existing hub first. Eufy lists the HomeBase S280, HomeBase Mini, the original HomeBase Professional, and eufy NVR recorders as not currently supported.
• Video smart locks will not pair. Locks like the FamiLock S3 Max connect to Wi-Fi on their own and do not link to this hub or the display.

Is This Deal Right for You?

This kit makes the most sense if you want to cover a large property without committing to monthly fees. It also suits anyone who prefers a single app for every camera.

It is a weaker fit if you already run a different eufy HomeBase, since the S4 cameras will not connect to it. It is also more system than you need if one or two cameras would cover your home.

Quick Questions

Is there a monthly fee?
No. Footage is stored locally on the HomeBase S380, and live viewing, recording, AI detection, and alerts all work without a subscription. Eufy does note that some optional premium features may need one.

Can the cameras record 24/7 on solar power alone?
No. Solar alone gives you motion-triggered recording. For 24/7 recording you need the included 14-foot cable kit, your own 5V/2A (or higher) power adapter, and up-to-date firmware.

Does it work with Apple Home?
No. Eufy lists Apple HomeKit as not currently supported, so iPhone owners use the eufy app. Alexa and Google Assistant are supported.

Will it work with my existing eufy hub?
Not if it is a HomeBase S280, HomeBase Mini, the original HomeBase Professional, or an eufy NVR recorder. Eufy lists those as not currently supported.

Do I need a professional installer?
No. The cameras mount with the included hardware, so you can set it up yourself.
