The Eufy Video Doorbell Wired S330 is a strong fit for a wired entrance where continuous power and two-camera coverage matter. It needs 16–24V, 30VA wiring and includes a chime, 2K HDR video, and 8GB of local storage.
Its main limits are clear: it doesn't connect to HomeBase or Apple HomeKit. If your wiring and smart-home setup fit, its dual cameras and package alerts make it a useful option to compare with other best wired video doorbells.
Eufy Video Doorbell Wired S330 review: who is it for?
The wired S330 fits homes with compatible doorbell wiring and an entrance that benefits from two camera views. Its design pairs a main camera with a second camera aimed toward the doorstep, helping you see more of the area near the door.
This model is worth considering if you want a wired doorbell, an included chime and video saved locally without monthly subscription fees. Eufy also includes Delivery Guard, which detects packages and can send arrival, pickup and tampering alerts.
The trade-offs may rule it out for some homes. It doesn't support HomeBase or Apple HomeKit, and the wiring must meet both the stated voltage and transformer rating.
eufy Security Video Doorbell: Best for dual-camera entrance coverage
- Wired 16–24V, 30VA
- Dual cameras
- 2K HDR video
- 8GB built-in storage
- Chime included
A wired doorbell for entrances where continuous power and coverage at more than one angle are priorities. Its included chime and built-in storage keep the setup focused, while HomeBase and Apple HomeKit support are absent.
Pros
- Dual cameras for front-door coverage
- 2K HDR video
- Chime included
- 8GB built-in storage
- No monthly subscription fees
Cons
- Requires compatible 16–24V, 30VA wiring
- Does not support HomeBase
- Does not support Apple HomeKit
What does the second camera add?
The second camera is meant to improve coverage around the front door, including the area directly below the main camera. That can help you see a package left close to the entrance, where a single forward-facing view may leave a blind spot.
Camera placement still matters. Door trim, a deep porch, side walls and the height of the mount affect what appears in each view, so check the installation position against the area you want to monitor.
What are the Eufy Wired S330's key features?
The Wired S330 combines dual cameras, 2K HDR video, package alerts, pre-roll previews and an included chime. Those features target common entrance needs: identifying visitors, noticing deliveries and hearing the bell inside.
| Feature | Eufy Video Doorbell Wired S330 |
|---|---|
| Power | Wired, 16–24V, 30VA |
| Camera setup | Dual cameras |
| Video | 2K HDR |
| Storage | 8GB built-in eMMC |
| Chime | Included |
| Package feature | Delivery Guard arrival, pickup and tampering alerts |
| Event preview | 3-second pre-roll |
| Smart assistants | Amazon Alexa and Google Assistant |
| HomeBase | Not supported |
| Apple HomeKit | Not supported |
The three-second pre-roll shows activity from before a motion event, which may help explain how someone approached the door. Motion alerts are the stated alert type, so think about whether that event-based approach suits your needs.
The chime is part of the package, but it's useful to compare chime needs before buying. Our guide to wired video doorbells with a chime covers the chime question across other options.
Is the wired S330 a good choice for continuous power?
Yes, if your existing doorbell circuit meets the 16–24V, 30VA requirement. Wiring lets the S330 draw power from the doorbell circuit rather than depending on a battery that needs periodic charging.
Check the transformer rating as well as the voltage. A circuit can fall within the voltage range but still miss the stated 30VA capacity, so confirm both values from the transformer label or have a qualified installer check them.
If the circuit isn't compatible, installation may require electrical work or another model. Don't assume that an old working doorbell guarantees the circuit meets this doorbell's requirements.
A wired doorbell can be convenient for a fixed entrance, but it doesn't provide backup power during an outage. If uninterrupted recording through a power loss is essential, consider what backup or separate camera coverage your home needs.
How does the S330 handle storage and subscriptions?
The Wired S330 has 8GB of built-in eMMC storage and no monthly subscription fees. That gives you local storage without a separate HomeBase, which the doorbell doesn't support.
Eufy says the 8GB can hold up to 90 days of video when recording 25 clips each day at 15 seconds per clip. Actual retention changes with event frequency and clip length, and the system overwrites the oldest videos when storage fills.
If local recording is a priority, compare the S330 with other wired video doorbells with local storage. Also check whether each model's storage method and retention behavior match how often you expect activity at your door.
A no-monthly-fee setup can still rely on an internet connection for alerts and remote access. Review the app and connectivity needs for your home before deciding that local storage alone covers every feature you want.
What should you know about alerts and package coverage?
Delivery Guard is the S330's package-focused feature, with alerts for delivery arrival, pickup and tampering. It can make the doorbell more useful if parcels are often left at your entrance.
Alert usefulness depends on where packages are placed and what the cameras can see. A tall box, a narrow step or a delivery left outside the camera views can affect what the doorbell captures.
Motion is the stated alert type, so expect alerts tied to detected activity rather than a promise that every visitor or parcel event will be identified. Set the device up with a clear view of the doorstep and review alert settings to reduce unwanted notifications.
What are the main drawbacks?
The S330's clearest drawbacks are its wiring requirement and limited platform compatibility. You need a compatible 16–24V, 30VA circuit, and the doorbell doesn't work with HomeBase or Apple HomeKit.
That matters if you already rely on HomeBase for other devices or want all smart-home controls in Apple's Home app. The S330 supports Alexa and Google Assistant instead.
The storage is built in, but its capacity is 8GB. Video retention varies with how often the doorbell records and how long events last, so a busy entrance may cycle through clips faster than Eufy's example estimate.
Should you choose the Wired S330 or another Eufy option?
Choose the Wired S330 when a doorbell is the main need; look at the Video Smart Lock S330 if you also want camera and lock functions. The lock combines a 2K camera and doorbell with fingerprint recognition, a keypad, app and voice access, and a traditional key.
The Video Smart Lock S330 is a larger change to the entrance than swapping a doorbell. It runs on a rechargeable 10,000 mAh battery and includes a chime, so compare its installation and access features with the wired S330's simpler doorbell role.
For views away from the front door, the 4G LTE Cam S330 is a different kind of device. It is an outdoor camera with 4K video, pan and tilt, Wi-Fi and 4G LTE connection options, plus a solar panel and battery.
If you don't have usable wiring, compare wireless video doorbells. For a broader comparison of the devices' roles, see video doorbell vs security camera.
Is the Eufy Video Doorbell Wired S330 worth considering?
Pick the Wired S330 if you have compatible wiring, want dual-camera entrance coverage and prefer local storage with no monthly subscription fees. Skip it if HomeBase or Apple HomeKit support is essential, or if your transformer can't meet the stated requirements.
For another wired option without a subscription, compare the best video doorbells without a subscription. If you need battery-powered installation instead, start with this Wyze Battery Video Doorbell review.
Is the Eufy Video Doorbell Wired S330 right for your entrance?
The Eufy Video Doorbell Wired S330 makes sense when wiring, dual-camera coverage and local storage line up with your setup. Confirm the transformer rating and check the camera views against your doorstep before choosing it.
Choose another model if the platform limits affect your home. Comparing the best wired video doorbells without a subscription can help you decide whether the S330's combination of power, coverage and storage is the right fit.
Frequently asked questions
Does the Eufy Video Doorbell Wired S330 need a battery?
The Eufy Video Doorbell Wired S330 is designed for 16–24V, 30VA wiring, so it can draw power from compatible doorbell wiring instead of relying on a rechargeable battery for its main power.

Yes, it has 8GB of built-in eMMC storage, and Eufy says it can hold up to 90 days of video under an example recording pattern of 25 clips per day at 15 seconds each. Actual capacity depends on how often events occur and how long clips run, and newer videos overwrite older ones when storage fills.
Can the Eufy Wired S330 work with Apple HomeKit?
No, the Wired S330 doesn't currently support Apple HomeKit. It works with Amazon Alexa and Google Assistant for voice control, so check that those options fit your home before choosing it.
