The eufy S330 is a wired video doorbell that runs on existing 16–24VAC doorbell wiring, so it stays powered and awake around the clock. It has a 2K HDR front camera and a second low-angle camera aimed at the package drop zone. Recordings are stored on the doorbell itself, so there is no subscription for watching your own footage. It suits homeowners who want constant power and package coverage and have a compatible transformer. Compared with battery doorbells, it avoids sleep and missed events, but installation requires adequate wiring.

The eufy Video Doorbell (Wired) S330 connects to your existing doorbell wiring, so it stays powered and awake around the clock. Unlike battery doorbells, it does not go to sleep to save power. It must be connected to existing wires.
The front camera records in 2K (2560×1920) with HDR, so visitors backlit by the sun can still be seen in color and clarity. A second, low-angle camera watches the area where packages are placed, keeping a delivered box in view. Every event starts with a 3-second preview, showing how a visitor approached your door and not just the moment motion triggered.
Recordings are stored on the doorbell itself. Watching your own footage does not require a subscription.
