Eufy S220 Vs. S330: Which Solar Security Camera Should You Buy?

I’ve been securing my home with wireless cameras for years now, and choosing between the Eufy SoloCam S220 and the eufyCam S330 was one of those decisions that had me weighing options carefully.

My goal here is to help you figure out which one fits your needs best by sharing my real experiences, breaking down the features, and giving you a clear, honest comparison so you can decide without regrets.

Key Differences Between Eufy S220 And S330

When I mounted the S220 on my garage and the S330 on my front porch, the contrasts became clear right away. I’ve used both for over a year in all kinds of weather, and these differences shaped how each performs day-to-day. Here’s a deeper look at what sets them apart, based on my real-world experience.

• Video Resolution and Image Quality — The Eufy S330’s 4K resolution captures incredibly sharp details compared to the S220’s 2K. I can zoom in on a delivery person’s face or read a license plate from across the driveway with the S330, while the S220 gets pixelated faster. During daytime, both look great, but the S330’s higher pixel count makes colors pop more vividly and edges crisper, especially on larger screens when reviewing footage.
• Solar Panel Efficiency and Charging Needs — The S330 has a noticeably larger and more efficient solar panel. It stays topped up with just 2 hours of sunlight, even on overcast days in my area. The S220 needs closer to 3-4 hours of direct sun, and in winter or shady spots, I’ve seen its battery dip below 80% more often, forcing occasional manual charges. This makes the S330 truly “forever power” in most setups.
• Storage Options and Capacity — This is a big one for me. The S220 has 8GB built-in, which holds about 2-3 months of event clips at moderate activity before looping. It’s super convenient—no extra gear—but fills up quick in busy areas. The S330 relies on the HomeBase 3, starting with 1TB (or expandable to 16TB), storing years of footage from multiple cameras without overwriting soon. Perfect if you’re building a system.
• AI Detection and Alert Accuracy — The S330’s BionicMind AI with dual radar + PIR sensors is game-changing. It recognizes faces I’ve taught it, spots vehicles or pets, and ignores branches swaying—I’ve cut false alerts by 90%. The S220 does solid human detection standalone, but gets more wind or animal triggers. Connecting S220 to HomeBase 3 adds facial recognition, but it’s not as advanced as the S330’s native setup.
• Night Vision Performance — No contest here—the S330’s color Starlight night vision plus spotlight shows full-color details in low light, making it easy to identify clothing or car colors at night. The S220 relies on infrared for black-and-white only, which is clear up to 30 feet but lacks that color context. The S330’s spotlight also deters intruders by lighting up the area.
• Hub Requirement and System Integration — The S220 shines as truly standalone—direct Wi-Fi connection, no hub needed. I set one up in minutes at a remote shed. The S330 requires the HomeBase 3 for everything, which adds centralized control, better range in big properties, and features like cross-camera tracking, but means extra cost and placement planning.
• Motion Detection Range and Reliability — Thanks to radar, the S330 detects motion farther and more accurately, even through light rain or fog. I’ve caught distant activity it flags reliably. The S220’s PIR is good but shorter range and more prone to misses in cold weather or with fast-moving objects.
• Build, Size, and Discreetness — The S220 is compact and blends in easily—great for not drawing attention. The S330 feels more robust and premium but bulkier due to the bigger panel and spotlight, making it more visible. Both are IP67 tough; they’ve survived heavy rain and freezes without issues.
• Connectivity and Signal Strength — S220 uses standard 2.4GHz Wi-Fi, which works fine but can struggle through thick walls. The S330’s proprietary link to HomeBase is rock-solid over longer distances, no dropouts even in my basement office viewing live feeds.
• Spotlight and Deterrence Features — The S330 has a built-in spotlight that activates on motion, flooding the area with light—super effective for scaring off critters or people. The S220 has no spotlight, relying only on the siren, which is loud but less visually intimidating.
• Battery Management and Power Consumption — Higher-res 4K and extras mean the S330 uses more power, but its efficient panel balances it. The S220 sips less overall, stretching those cloudy days better standalone.
• Expandability and Multi-Camera Setup — If you’re starting small, S220 is ideal—one or two cams, no fuss. For whole-home coverage, S330 integrates seamlessly with more cameras, sharing storage and AI across the system.
• Price vs. Value Trade-Off — S220 is cheaper upfront and ongoing, perfect for budget spot monitoring. S330 costs more (especially with HomeBase) but delivers pro-level features that justify it for serious security.
• App Experience and Customization — Both use the same app, but S330 unlocks deeper options like vehicle detection zones or personalized face alerts. S220 keeps it simpler, which I appreciate for quick checks.

These differences made me realize they’re aimed at slightly different users—one for simple, no-fuss monitoring, the other for a full-featured system.
