Specs: 3K Panoramic vs Dual Lens

Video resolution

Edge: eufy Security 3K Wired Doorbell Cam S4

The eufy Security 3K Wired Doorbell Cam S4 captures footage at 9 MP, which is labeled as 3K Ultra HD. This higher pixel count allows for sharper details, making it easier to identify faces or read license plates from a distance. In contrast, the eufy Dual Camera Video Doorbell with HomeBase records at 2K Full HD. While 2K is clear, the S4’s 3K resolution provides more data for zooming in on specific areas without losing clarity. If you need maximum detail in every frame, the higher megapixel count of the S4 offers a tangible advantage for scrutiny.

Camera design

Edge: Tie

These two doorbells use completely different optical approaches. The S4 features a single lens capable of a 180° × 180° panoramic view, covering wall to wall and ground to ceiling. It also includes VR mode for exploring the full scene. The Dual Camera model uses two separate lenses: one facing forward for people and another facing down for the floor. This dual setup ensures a head-to-toe view without blind spots near the ground. The S4 offers a wider single perspective, while the dual camera ensures the doorstep floor is always visible.

Power source

Edge: eufy Dual Camera Video Doorbell with HomeBase

Power options differ significantly between these models. The eufy Security 3K Wired Doorbell Cam S4 is wired only, requiring a constant connection to your doorbell transformer for operation. This eliminates the need to worry about battery levels. The eufy Dual Camera Video Doorbell with HomeBase supports both wired and battery power. This flexibility allows you to install it in locations without existing wiring or use a battery backup if the power goes out. If you lack a wired setup or want redundancy, the dual power option is more versatile.

Storage capacity

Edge: eufy Dual Camera Video Doorbell with HomeBase

Both devices prioritize local storage with no monthly fees, but the built-in capacity varies. The S4 includes 4GB of eMMC storage, which is quite limited for continuous recording. However, it supports expansion via an SD card up to 1TB. The Dual Camera model comes with 16GB of built-in storage and can expand up to 16TB. The larger built-in memory and higher expansion limit on the dual camera model mean you may not need to purchase an SD card immediately, offering more out-of-the-box retention for your footage.

Smart features

Edge: Tie

Intelligent tracking and recognition differ between the two. The S4 uses OmniTrack AI to lock onto persons and auto-frame them, keeping the subject centered in the 180° view. It also supports Google Assistant, Alexa, and Apple HomeKit. The Dual Camera model utilizes BionicMind technology for facial recognition and self-learning AI that claims 99.9% accuracy. It categorizes security reports automatically. While the S4 excels at active tracking during events, the dual camera focuses on refined alert filtering and recognition accuracy to reduce false notifications.

Included accessories

Edge: eufy Security 3K Wired Doorbell Cam S4

What you get in the box affects your initial setup experience. The eufy Security 3K Wired Doorbell Cam S4 includes the Chime 2, which provides an indoor audio notification for visitors at your door. This is a useful addition if you are not always near your phone. The eufy Dual Camera Video Doorbell with HomeBase includes the HomeBase 3 unit, which acts as the hub for local storage and connectivity.
