Eufy Security Video Doorbell Dual Camera S330

Pros

• Pre-roll buffer ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 5.0
  The wired dual camera version adds a short pre roll buffer of around three seconds before motion is detected so recordings start slightly earlier, helping capture visitors as they walk up instead of cutting in midway through an event.
• Theft & Tamper ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 5.0
• Subscription ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.9
  Across reviews the lack of a required cloud plan is a major selling point, since full event history and smart features work with local storage alone, and this test again emphasizes that you can review recordings and use the doorbell to its full potential without paying any ongoing fees.
• Ongoing ownership costs ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.9
  Owners consistently praise the predictable, low ongoing costs because local storage and optional cloud backup mean there are no mandatory monthly charges, and this review underscores that benefit by highlighting the doorbell as a strong choice for households watching their budgets.

• Delivery package monitoring ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.7
  Dual cameras and intelligent delivery features give the doorbell strong package awareness, combining a downward-facing lens with package-specific alerts, and recent tests highlight how it consistently captures drop-offs, keeps boxes in frame alongside visitors, and avoids mislabeling non-package items as deliveries.
• Dual-camera design ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.7
  Dual front and downward cameras work together to capture visitors and doorstep packages with fewer blind spots and less fisheye distortion than single lens designs, and in everyday use this owner has found the extra package camera and its adjustable angle genuinely helpful for monitoring parcels even if it is not strictly essential, with Delivery Guard using the second view to flag most deliveries successfully.
• System completeness ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.7
  The system is sold as a fairly complete kit that includes the dual camera doorbell, plug in chime, mounting template, angle wedge, jumper wires, and clear instructions so most buyers have what they need out of the box, and this user highlights that the extra chime was actually redundant in their wired setup because the HomeBase and existing chime already provided ample audible alerts.

• Reliability (general) ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.6
  Owners who have tried multiple brands describe this doorbell as generally more reliable than subscription based models once power and Wi Fi are properly sized, and this reviewer reports that over two years of everyday use the unit has delivered consistently strong video quality and alerts with only the expected live view and audio lag seen on many battery systems, issues that have not meaningfully affected their confidence in the device.

• Storage ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 8 reviews 4.4
  Reviewers value the built in 16 GB storage on the HomeBase, which can hold several months of typical motion clips and reduces reliance on the cloud, and this review reiterates that the base station keeps footage available for later review without a subscription and is sized around six months of 20 second events.
• Chime ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.4
  Between the HomeBase acting as a chime and support for existing wired chimes, most setups get loud, reliable ringing indoors, and this review reinforces that the bundled base station provides instant audible alerts so you do not need to buy an extra plug in chime like with many rivals.
• AI features ★ ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 4.4
  Onboard AI goes beyond basic motion by classifying people, packages, and familiar faces, and recent testing notes that the system reliably tagged deliveries while avoiding false package alerts, with deterrent voice messages available when someone approaches parcels.

• Price & value ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 4.1
  Although the upfront price is higher than some basic rivals, reviewers generally see strong long term value because dual cameras, rich AI, and local storage come without mandatory subscription fees, and this review explicitly calls the unit exceptional value for money given its features and lack of ongoing costs.
• Motion detection performance ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 4.0
  Earlier reviews describe the dual detection system as quick to pick up relevant visitors and parcels while avoiding most false alarms, and the latest testing again found that packages in view and motion around the doorway were detected promptly with alerts that felt timely in normal household use.
• Face recognition ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.0
  Multiple reviews find facial recognition useful for tracking kids, family, and caregivers, with generally reliable name tagging when lighting is good, and this test goes further by reporting that familiar faces were identified correctly during trials with no false positives, making the feature genuinely practical rather than a gimmick.
• Quick-reply / pre-recorded message usefulness ★ ★ ★ ★ ★ ★ ★ ★ ★ 4 reviews 4.0
  Owners appreciate having quick replies and ring auto responses to play short prerecorded messages to callers or people near packages, and this review adds that the three presets plus the option to record a custom clip make it handy when you are busy or want the doorbell to speak firmly to anyone approaching a delivery.
• Design aesthetics ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 4.0
  Owners often describe the glossy black, modern styling as attractive on most exteriors, and this review likewise praises the sleek rectangular shape and LED ring, even while acknowledging that the body is chunkier than the slimmest video doorbells on the market.
• Price & Value ★ ★ ★ ★ ★ ★ ★ ★ ★ 1 review 4.0
• Notifications ★ ★ ★ ★ ★ ★ ★ ★ ★ 7 reviews 3.9
  Notifications remain clearly labeled for people and packages, but while some users report reasonably prompt alerts, other testing has seen motion and delivery notifications arrive several seconds late and live feeds loading after visitors have already left, making speed and responsiveness more mixed than the feature set suggests.
• Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread) ★ ★ ★ ★ ★ ★ ★ ★ ★ 6 reviews 3.8
  Earlier coverage points out that the doorbell works with Alexa and Google Assistant for voice and smart display viewing but lacks HomeKit, and this review echoes that split, noting smooth integration with Amazon and Google ecosystems while confirming that Apple smart home users should look elsewhere.
• Battery & Charging ★ ★ ★ ★ ★ ★ ★ ★ ★ 3 reviews 3.8
• Audio ★ ★ ★ ★ ★ ★ ★ ★ ★ 5 reviews 3.8
  Past tests describe two way audio as full duplex and generally clear, though a bit thin on the speaker side, and this review agrees that the built in mic and speaker make conversations easy to follow even if the sound quality is more solid than spectacular.
