eufy Security Video Doorbell S330 with HomeBase 3: features and specs

The eufy Security Video Doorbell S330 is a battery-powered doorbell with two cameras, sold here with the S380 HomeBase (HomeBase 3). The pairing is designed so recordings are kept locally rather than through a subscription. This page explains what the dual camera and dual motion detection do, and how the local storage works.

Two cameras, fewer blind spots

Most video doorbells have one camera facing straight out, which often cuts off the ground in front of the door. eufy says the S330 adds a second, low-angle camera so the doorstep is in full view, including where a parcel might be left. Two views can give you a head-to-toe picture of a visitor and whatever they set down.

2K video with HDR

The main video is 2K, which eufy says allows visitors to be identified from the details. HDR (high dynamic range) balances very bright and very dark areas in the same frame. That helps with a common doorbell problem: someone standing in front of strong sun, where a normal camera shows only a dark silhouette. eufy says HDR keeps backlit visitors visible in clear colour.

Dual motion detection

The doorbell uses two sensors together:

• PIR (passive infrared) senses body heat moving, and is best at close range.
• Radar can detect movement farther away.

eufy says combining them lets the doorbell tell near and far subjects apart and cut false alarms by 95%. That is the brand's figure; real results depend on where the doorbell is mounted and what passes in front of it. Most systems let you adjust sensitivity and detection zones in the app, which helps if you face a busy street.

HomeBase 3 and local storage

HomeBase 3 is a hub that sits indoors, connects to your network and holds recordings. The listing states the doorbell has 16GB of built-in capacity that is expandable up to 16TB, which eufy presents as a way to save recordings locally without a subscription. eufy also notes that push notifications with thumbnail previews temporarily keep thumbnail images in the cloud, and that the operating system takes up part of the built-in storage.

Local storage appeals to people who prefer to keep footage at home. It also means the hub, and any storage you add, become part of your security setup, so it needs a sensible indoor position and a power outlet.

Working with other eufy devices

eufy says HomeBase 3 uses its BionicMind system to let compatible eufy Security devices work together through one app. The listing says HomeBase 3 works with most eufy Security devices, so check the current compatibility list for any cameras you already own or plan to add.

What's included

The listing describes a bundle: the S330 dual camera doorbell plus the S380 HomeBase. Confirm the exact contents, including mounting hardware and any chime, on the product page before you order.

What to check before you buy

• Mounting: battery doorbells usually mount with screws or an adhesive bracket; check what suits your door frame and whether a wedge is needed to adjust the angle.
• Wi-Fi and hub placement: the HomeBase needs a network connection and a spot within range of the doorbell.
• Chime: find out how you will be alerted indoors, through the app, the hub or a separate chime.
• Battery: battery life depends on how often the doorbell is triggered and on the weather. Check how to recharge it and how long that takes.
• Storage: decide how much extra storage you need and which drive types the HomeBase supports.
• Privacy: check local rules and your neighbours' expectations about cameras that face shared areas.
