eufy Video Doorbell S330 Add-On: features, specs and who it suits

The eufy Security Video Doorbell S330 is a battery-powered doorbell with a camera that shows your front step in 2K. It is sold as an add-on unit, which means it connects to an existing eufy HomeBase rather than working alone. It is aimed at people who want to see both visitors and parcels without wiring.

Two cameras, fewer blind spots

Most doorbell cameras look straight ahead, so the ground at the door can fall out of view. eufy says the S330 solves this with two cameras, one of them angled low, so a parcel sitting at the door stays in frame. The unit measures 6.5 x 2.2 x 1.2 inches and weighs 0.8 lb.

2K video with HDR

2K resolution gives more detail than standard 1080p, which helps when you need to identify a face. HDR, short for high dynamic range, balances bright and dark areas of a scene. eufy points to its value when a visitor stands with the sun behind them, a case where basic cameras often show only a silhouette.

Dual motion detection

The S330 combines a PIR sensor, which senses body heat, with radar. eufy says this lets it tell nearby and distant subjects apart and cuts false alarms by 95%. That is the brand's own figure, and results vary with where the doorbell is mounted and how you set the sensitivity.

Package and family features

Delivery Guard is eufy's name for parcel alerts. You are notified when a package arrives, get a reminder to pick it up and receive an alert if someone approaches it. The listing also mentions family recognition. Recognition tools of this kind generally work best with a clear view of the face.

What the add-on needs

This is the most important detail on the listing. The add-on unit requires a HomeBase 2 or HomeBase 3 to work, and it connects only to 2.4GHz Wi-Fi networks. If you already own a compatible HomeBase, this is a straightforward addition. If not, you will need to get one separately.

Who it suits

It suits households that already use eufy cameras and want a doorbell on the same system, or those who worry about porch deliveries. It is less suitable for anyone whose router offers only 5GHz, or who does not want a separate base station.

What to check before you buy

• Base station: confirm that you have a HomeBase 2 or 3.
• Wi-Fi: check that your network offers 2.4GHz where the doorbell will be fixed.
• Mounting: look at the door frame, the viewing angle and whether you can recharge it.
• Chime: see how the doorbell rings inside your home, as the manual describes.
• Privacy rules: local laws on recording neighbours or public areas vary.
