Cam S330 (eufyCam 3) Add-on Camera

The eufyCam S330 (eufyCam 3) Add-on Camera brings 4K resolution and facial recognition to an existing eufy Security system — sharp enough to make out a license plate roughly 10 meters out, powered by an integrated solar panel that can keep it running indefinitely. It's the top tier of eufy's add-on camera lineup, and like the others, it needs a HomeBase 3 already installed to work at all.

Requires HomeBase 3 — Not a Starter Camera

Same rule as every add-on camera in this range: the eufycam s330 will not connect or record anything without an existing HomeBase 3 already set up in your home. There's no standalone mode. If you're starting from scratch, a bundled kit with the hub included makes more sense — the SoloCam S340 (2-Cam Kit) comes with everything needed in one box. This camera is specifically for extending a HomeBase 3 setup you already own.

If you're deciding between add-on tiers, the eufyCam S220 (2C Pro) covers 2K at a lower price but uses the older HomeBase 2 — the two aren't interchangeable, so which one fits depends entirely on which hub you're already running.

What the eufyCam 3 Delivers

True 4K Detail, Not Marketing 4K

An 8-megapixel sensor paired with an f/1.4 aperture captures genuinely sharp footage — clear enough to read a license plate at roughly 10 meters, which is a meaningfully different capability from cameras that call themselves "HD" but blur out anything past a few meters. For a driveway gate or a wide property entrance, that resolution is the entire point of paying more for this tier.

Facial Recognition That Improves Over Time

BionicMind AI learns from every face and body-shape scan it processes, refining accuracy the longer it runs — eufy states it reaches over 99.9% accuracy over time. In practical terms, it can tell you "your daughter is at the door" instead of just "a person is at the door," and that distinction cuts down false alerts dramatically once the system has had a few weeks to learn your household.

Solar Power Built for Genuinely Unattended Operation

A 13,000mAh internal battery, kept topped up by an integrated SunPower solar panel rated at 25% efficiency, needs only about two hours of direct sunlight to run a full day and night. Without any sun at all, the battery alone lasts up to 365 days. For Dubai's sun exposure, that's about as close to permanently maintenance-free as a security camera gets.

Color Night Vision and Motion-Activated Spotlight

A built-in spotlight triggers on detected motion, switching footage from infrared to full color — useful for identifying clothing or vehicle color after dark, not just confirming a shape moved.

Expandable Local Storage

Recordings store on 16GB of built-in local storage by default, with the option to expand up to 16TB via an external hard drive for households running multiple cameras and wanting months of footage on hand rather than weeks.

Compatibility Before You Order

This camera requires HomeBase 3 specifically — it's not compatible with the older HomeBase 2 used by the eufyCam 2C and 2C Pro lines. HomeBase 3 itself supports all current eufyCam models along with most eufy battery doorbells and sensors, so if you're already running HomeBase 3 for other devices, this camera slots straight in. It currently works with Alexa and Google Assistant; Apple HomeKit support isn't available on this model yet.

Frequently Asked Questions

Does this camera work without HomeBase 3?

No. It's an add-on camera that requires an existing HomeBase 3 to operate — there's no standalone Wi-Fi mode, so it can't be your first eufy camera.

How long does the battery last without sunlight?

Up to 365 days on the internal 13,000mAh battery alone. With roughly two hours of direct sunlight a day, the solar panel keeps it running indefinitely without needing to fall back on stored charge.

What does facial recognition actually do here?

BionicMind AI learns to distinguish family members from strangers over time, so alerts can tell you who's at the door rather than just that motion was detected. Accuracy improves the longer the system runs.

Is it compatible with the older HomeBase 2?

No. eufyCam 3 requires HomeBase 3 specifically. It's not interchangeable with the HomeBase 2 used by the eufyCam 2C and 2C Pro add-on cameras.

Does it work with Apple HomeKit?

Not currently. It supports Alexa and Google Assistant. eufy has noted HomeKit support is in development but hasn't shipped for this model yet.
