What are the main differences between EUFY S330 and S3 Pro?

Answer in one sentence: The EUFY S3 Pro adds MaxColor Vision night view, PIR + radar motion detection, 24/7 recording, SolarPlus 2.0 charging, and Apple HomeKit support — five flagship features the S330 lacks.
🌙

① Night Vision Technology

S3 Pro wins. MaxColor Vision uses an upgraded f/1.0 sensor + adaptive spotlight to deliver full-color footage in near darkness. The S330's color night view depends more on a fixed spotlight, which can wash out fine detail.

S3 Pro 採用 f/1.0 大光圈 + 自適應補光燈,近黑環境下仍能錄到真彩細節;S330 在黑暗中依賴固定亮度補光燈。
📡

② Radar Motion Detection

S3 Pro wins. Dual PIR + radar sensors detect motion up to 40 feet (~12 m) and dramatically reduce false alerts from leaves, shadows, or heat shifts. S330 uses PIR only at 30 ft.

S3 Pro 同時搭載 PIR + 雷達,偵測距離 40 呎(12 米),大幅降低誤報;S330 僅有 PIR、30 呎範圍。
🎥

③ 24/7 Continuous Recording

S3 Pro wins. When connected via USB-C power, the S3 Pro records continuously 24/7 — ideal for driveways, storefronts, or vacation rentals. The S330 only records on motion triggers.

S3 Pro 接 USB-C 電源後可 24/7 連續錄影,適合車道、店面、民宿;S330 僅動態觸發。
🍎

④ Apple HomeKit Support

S3 Pro wins. S3 Pro is fully Apple HomeKit Secure Video compatible. S330 supports only Alexa and Google Assistant — a deal-breaker for iPhone-first households.

S3 Pro 完整支援 Apple HomeKit Secure Video;S330 僅 Alexa 與 Google Assistant。
☀️

⑤ Solar Charging Efficiency

S3 Pro wins. SolarPlus 2.0 panels need only ~2 hours of direct sunlight per day to stay fully charged — even in cloudy climates. S330's panel is reliable but less efficient in low light.

SolarPlus 2.0 每日僅需 2 小時直射陽光即可滿電,多雲地區更具優勢。
💰

⑥ Value-for-Money

S330 wins. At similar list prices, S330 sees deeper discounts during seasonal sales — making it the better value pick for buyers not needing radar, MaxColor, or HomeKit.

促銷期間 S330 降價幅度更大,是不需旗艦功能用戶的最高 CP 值選擇。

Which EUFY camera should you buy in 2026?

  • Care about minimal false alerts (radar filtering).

🏆 Final Verdict / 最終建議

The EUFY S3 Pro is the technically better camera — full stop. It wins on night vision, detection range, recording flexibility, and smart home integration.

If budget allows and you want one-and-done future-proofing, go S3 Pro. For maximum value per dollar, go S330.

S3 Pro 規格全面勝出;但對大多數只需可靠 4K 戶外監控的家庭,S330 才是更聰明的選擇。預算充足追求一次到位選 S3 Pro,追求 CP 值選 S330。
