Features
Why it's the Pro.
Six things that make the eufyCam S3 Pro the best 4K security camera without a subscription.
MaxColor Vision
Night that looks like day.
A 1/1.8-inch CMOS sensor with an industry-leading f/1.0 aperture pulls in more light than any competing security camera. Combined with an AI-powered ISP, it delivers full-colour footage in pitch darkness, no spotlight needed.
Resolution
4K UHD, every frame.
3840 × 2160 resolution captures faces and licence plates up to 9 metres away. Even at night, in minimal ambient light, the detail is sharp enough to actually be useful.
Power
Solar-powered, year-round.
SolarPlus 2.0 built-in panel keeps it charged with as little as 1 hour of direct sunlight per day. The 13,000 mAh battery handles cloudy stretches. Add the optional external panel for shady mounting spots.
Detection
Radar + PIR, 99% fewer false alerts.
Dual motion detection filters out insects, rain, shadows, and wind. You get alerted for humans and vehicles. Not for that one leaf that's been annoying you since autumn.
AI
BionicMind facial recognition.
Via the HomeBase S380, the camera learns faces over time. It tells you who's at the door by name, not just "a person." Cross-camera tracking stitches clips across multiple cameras into one event timeline.
Smart Home
HomeKit, Alexa & Google.
One of the few 4K security cameras that actually supports Apple HomeKit. Also works with Alexa and Google Assistant. HomeKit video streams at 1080p via the Home app.
Night vision
Three modes.
Fewer blind spots.
Fewer blind spots.
MaxColor for full colour in the dark. Adaptive Spotlight for motion-triggered illumination. Infrared for classic stealth.

Auto compare
MaxColor Vision
Full colour, no spotlight.
The f/1.0 aperture and AI ISP work together to produce vivid, detailed footage even in near-total darkness. Faces and clothing colours are clearly identifiable without alerting anyone with a bright light.
Adaptive Spotlight
Light where it matters.
Motion-triggered spotlight activates only when movement is detected. Tap a specific area in the app to focus the light for optimal footage without overexposure. Also works as a deterrent.
Security
Detect. Deter. Done.
Radar + PIR dual sensors with siren and motion-activated voice warnings.
Deterrence
Siren + voice warnings.
Set the camera to sound a loud siren or customisable motion-activated voice warnings to deter intruders. Because sometimes the best security is making sure they know you're watching.
Zones
You choose what triggers it.
Draw custom activity zones in the app to only monitor the areas you care about. Ignore the footpath. Focus on the driveway. Human and vehicle detection means your cat won't wake you up at 3am.
Power
Always on.
Rain or shine.
Rain or shine.
SolarPlus 2.0 built-in panel with a 13,000 mAh battery backup. Up to 365 days on a single charge.
Daily solar harvest vs consumption
+525 mAh net
0↑ 150 mAh daily use900 mAh
Built-in Panel
50% more efficient than last gen.
Collects 450–900 mAh per day in optimal sunlight. The camera only uses 100–200 mAh per day on average. Starts charging at just 2,500 lux, and partial shade won't stop it thanks to advanced circuitry design.
External Panel
For the shady spots.
Mount the camera under eaves or in shade, then run the external solar panel (sold separately for add-on units) to a sunnier spot. Both panels work together for maximum charging flexibility.
The vibe
Most cameras show you a blurry grey blob at night and call it "night vision." The S3 Pro shows you who's there, what they're wearing, and what colour their car is.
That f/1.0 aperture is the biggest on any consumer security camera we've come across. It's the same approach proper photographers use: open the aperture wider and more light hits the sensor. Simple physics, executed really well.
Pair that with an AI-powered image signal processor and you get night footage that genuinely looks like daytime. No spotlight giving away your camera position. No washed-out infrared. Just clean, full-colour detail.
Add in radar + PIR detection that actually knows the difference between a person and a possum, solar charging that handles Australian conditions, and zero monthly fees, and you've got a camera that does exactly what it should without nickel-and-diming you.
Inspired by Zaha Hadid's architecture. Designed to disappear into your home.
⚠ The honest bit
Read this first.
This camera requires a HomeBase S380 (HomeBase 3).
The eufyCam S3 Pro is NOT a standalone camera. It pairs exclusively with the HomeBase S380 (model T8030). It will not work with HomeBase 2, HomeBase Mini, HomeBase Professional, or any older base station. If you don't already own a HomeBase S380, you'll need to purchase one separately.
Storage is on the HomeBase, not the camera.
The camera itself has no built-in storage. All footage is stored on the HomeBase S380, which comes with 16GB built-in eMMC storage. You can expand it up to 16TB by installing a hard drive or SSD into the HomeBase's internal SATA bay.
24/7 continuous recording is possible.
But it requires a wired USB-C power connection (5V/2A adapter, sold separately). On battery/solar alone, the camera records on motion events and supports periodic 24/7 Snapshots to fill in the gaps between events.
Wi-Fi: 2.4GHz only.
The S3 Pro connects to your HomeBase via 2.4GHz Wi-Fi. It does not support 5GHz networks. Make sure your router has 2.4GHz enabled.
Condition: New, No Box.
This unit was split from a brand new, factory-sealed eufyCam S3 Pro multi-camera kit. It has never been used, paired, or activated. Every accessory that comes with a single add-on unit is included. The only thing missing is the retail box. That's why the price is lower.
No charger in the pack.
The camera charges via USB-C. A charging cable is included, but a power adapter is not. BYO any USB-C adapter rated 5V/2A or above.

Getting started
Setup in 3 steps.
No electrician. No subscription. No drama.
1
Charge and download.
Charge the camera via the included USB-C cable (BYO 5V/2A adapter, 6–8 hours for full charge). Download the free eufy Security app (iOS or Android) and create an account.
2
Pair via HomeBase S380.
Open the eufy app, select your HomeBase S380, and add a new device. Press the sync button on the camera and follow the in-app prompts. Keep the camera within 1 metre of the HomeBase during pairing.
3
Mount and go.
Mount the camera at 2–3 metres height using the included bracket, screws, and positioning sticker. Point the solar panel toward the sun. Remove the lens film, adjust the angle in the app, and you're live.
Pro Tip: Update your HomeBase S380 firmware to V3.5.9.7 or later and the camera to V3.0.9.3 or later before setup. This ensures HomeKit compatibility and all AI features work correctly.

FAQ
Common questions.
Q "New — No Box"… so is it actually new? ⌄
Yes. This camera was split from a brand new, factory-sealed eufyCam S3 Pro multi-camera kit. It has never been used, paired, or activated. Everything that ships with a single add-on unit is included. The only thing missing is the retail box. That's why the price is lower.
Q Will it work without a HomeBase? ⌄
No. The eufyCam S3 Pro requires a HomeBase S380 (HomeBase 3, model T8030) to function. It will not work standalone or with any older HomeBase model. If you need a standalone camera, look at the eufyCam S4 instead.
Q I already have a HomeBase S380. Will this just pair and work? ⌄
Yes. Make sure your HomeBase S380 firmware is updated to V3.5.9.7 or later and your app is up to date. Then add the camera via the app. You'll get BionicMind facial recognition, cross-camera tracking, and expandable storage up to 16TB.
Q Does it work with Apple HomeKit? ⌄
Yes. The eufyCam S3 Pro supports Apple HomeKit. Video streams at 1080p via the Home app. Make sure both the HomeBase and camera firmware are up to date and complete the HomeKit Setup in the Security app settings.
Q Is there a monthly subscription? ⌄
No. Core features (recording, AI detection, facial recognition, alerts, live view, two-way audio) all work with no ongoing fees. Footage is stored locally on the HomeBase. Optional cloud storage is available, but standard functionality is subscription-free.
Q What's MaxColor Vision? ⌄
It's the S3 Pro's colour night vision technology. A massive 1/1.8-inch sensor with an f/1.0 aperture (the widest on any consumer security camera) plus an AI-powered image processor captures full-colour footage in near-total darkness, without needing a spotlight.
Q I'm in Australia. Will this work here? ⌄
Yes. The camera charges via USB-C, so you can use any Australian USB-C adapter rated 5V/2A or above (not included). It connects to standard 2.4GHz Wi-Fi via the HomeBase. CamGuard is based in Townsville, QLD, so support is local.
