The outdoor security camera market is divided into two distinct philosophies in 2026. One side wants you to pay a monthly subscription for cloud storage and advanced AI. The other side promises a one-time purchase with zero hidden fees.
Leading the "Subscription" camp is the Arlo Pro 5S 2K, known for its polished app and ecosystem. Leading the "Free Forever" camp is the EufyCam 3 (S330), boasting 4K resolution and built-in solar panels. Which system protects your home better? In this comprehensive review, we analyze the hidden costs and video performance of both.
The Big Divide: Subscription vs. Local Storage
Before looking at the lenses, look at your wallet.
Arlo Pro 5S (The Subscription Model)
Arlo hardware is excellent, but it is crippled without a plan.
Without a Subscription ("Arlo Secure"): You get live streaming and motion alerts. That's it. No cloud recording, no rich notifications, and no object detection (person vs. animal).
Cost: Expect to pay ~$13/month for unlimited cameras.
EufyCam 3 (The Local Storage Model)
Eufy comes with a "HomeBase 3" hard drive that sits inside your house.
The Benefit: All footage is stored locally on the HomeBase. You get 4K recording, face recognition (BionicMind), and vehicle detection for $0/month. You own your data.
Power Source: "Forever Power" vs. Batteries
Climbing a ladder to charge cameras is annoying.
- EufyCam 3: Has a solar panel integrated directly into the top of the camera. As long as it gets 2 hours of direct sunlight daily, you never have to charge it. It truly offers "Forever Power."
- Arlo Pro 5S: Uses a removable rechargeable battery. It lasts 3-6 months depending on usage. You can buy a separate solar panel, but it’s an ugly extra wire and an extra cost (~$50).
Video Quality: 4K vs. 2K
Numbers don't lie, but they aren't everything.
Eufy (4K): The detail is incredible. You can zoom in on a license plate 20 feet away and read the numbers. The digital zoom remains sharp.
Arlo (2K with HDR): While lower resolution, Arlo’s color science is superior. Its HDR (High Dynamic Range) handles shadows better. If your porch is half in the sun and half in the shade, Arlo will show both clearly, while Eufy might struggle with the contrast.

FAQ: Installation & Range
How far can the cameras be from the base?
Eufy’s HomeBase 3 uses a proprietary low-frequency Wi-Fi that penetrates walls better than standard Wi-Fi. You can easily place cameras 50-70 feet away from the house. Arlo connects to your router, so range depends on your own Wi-Fi strength.
Does Eufy really recognize faces?
Yes. The "BionicMind" AI is impressive. After a week, it learns your family members. Instead of "Motion Detected," your phone says "John is approaching." This reduces false alarms significantly.
Buy EufyCam 3 if: You have a sunny yard and refuse to pay monthly subscriptions. The upfront cost is higher, but it pays for itself in 2 years.
Buy Arlo Pro 5S if: You prioritize cloud backup safety, have a lot of shady areas (where solar won't work), or want the widest field of view (160°).
