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 Visionuses 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.

The S3 Pro features an f/1.0 large aperture + adaptive fill light, allowing it to capture true color details even in near-black environments; the S330 relies on a fixed brightness fill light in the dark.
📡

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 is equipped with both PIR and radar, with a detection range of 40 feet (12 meters), significantly reducing false alarms; S330 only has PIR, with a range of 30 feet.
🎥

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 can continuously record 24/7 after connecting to USB-C power, suitable for driveways, stores, and homestays; S330 only triggers dynamically.
🍎

④ Apple HomeKit Support

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

S3 Pro fully supports Apple HomeKit Secure Video; S330 only supports Alexa and Google Assistant.
☀️

⑤ Solar Charging Efficiency

S3 Pro wins. SolarPlus 2.0Panels 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 only needs 2 hours of direct sunlight per day to be fully charged, and it is even more advantageous in cloudy areas.
💰

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.

During the promotional period, the S330 has a larger price reduction, making it the best value option for users who don't need flagship features.
