The eufy Video Smart Lock E330 and S330 combine a fingerprint lock, keypad, 2K door camera, and video doorbell in one front-door device. They look similar and share many of the same basic features, but their storage, Wi-Fi connection, included accessories, and detection features are not identical.
The E330 is the simpler and currently less expensive choice. It connects directly to Wi-Fi and stores recordings in its built-in 8GB eMMC storage. The S330 includes a separate indoor chime that also acts as its Wi-Fi bridge, and it supports expandable local storage through an SD card.
The right choice depends less on the appearance of the lock and more on whether you want the lowest upfront cost or the additional chime, storage expansion, and detection features included with the S330.
The Short Answer
Choose the eufy E330 if you want the lower-priced option, direct Wi-Fi connectivity, and built-in local storage without needing a separate indoor chime. It provides the main features most buyers are looking for: fingerprint entry, keypad access, a 2K camera, video doorbell, app control, and no required monthly storage fee.
Choose the eufy S330 if you want an included indoor chime, expandable SD-card storage, and additional detection features for activity around the door. It costs more, but the extra hardware may make sense for a busy front entrance or a household that wants more locally stored clips.
For most value-focused buyers, the E330 is the more practical starting point. The S330 is the better-equipped package.

The Biggest Differences Between the E330 and S330
1. The E330 Uses Direct Wi-Fi
The E330 connects directly to the home’s 2.4 GHz Wi-Fi network. There is no separate indoor chime acting as the required Wi-Fi bridge.
This makes the package simpler, but the connection still depends on reliable Wi-Fi coverage at the front door. Exterior walls, metal doors, brick, and the distance from the router can all affect performance.
2. The S330 Includes a Chime and Wi-Fi Bridge
The S330 includes an indoor chime that also helps connect the lock to the home network. The chime should be installed indoors and positioned within the manufacturer’s recommended range of the lock.
This arrangement adds another device, but it gives the household a separate indoor doorbell sound and provides the storage point for recorded video.
3. Their Local Storage Works Differently
The E330 includes 8GB of built-in eMMC storage inside the device. It can record useful door events without requiring a monthly cloud-storage plan.
The S330 stores recordings through the included chime and supports an SD card up to 128GB. The SD card is normally purchased separately. This makes the S330 more flexible for buyers who want to expand local storage.
Local storage and optional cloud services are not the same thing. Cloud backup and some cloud-dependent notification features may still involve online processing or an optional paid service. Our local storage vs cloud security cameras guide explains the broader trade-off.
4. The S330 Adds More Detection Options
Both locks use motion detection around the door. The S330 also lists more advanced detection for activities such as someone leaving, lingering near the door, and automatically locking after the door is properly closed.
These additions may be useful at a busy front entrance, but they should not be treated as a complete home-security or alarm system.
5. The E330 Costs Less
Based on the supplied Canadian listings, the E330 is currently priced at CA$170.96 and the S330 at CA$225.66.
That makes the E330 approximately CA$54.70 less expensive at the time of writing. The difference may justify choosing the E330 if built-in storage is enough and a separate indoor chime is not important.
Prices and promotions can change, so the decision should be based on the latest price shown at checkout.
What Both Smart Locks Have in Common
- 2K front-door camera
- Built-in video doorbell
- Two-way audio
- Fingerprint recognition
- Touchscreen keypad
- App control
- Alexa and Google Assistant compatibility
- Physical backup keys
- Rechargeable 10,000mAh battery
- Low-battery notifications
- Emergency exterior power port
- Automatic locking
- IP65-rated exterior hardware
- Local storage without a required monthly fee
Neither model currently supports Apple HomeKit or Matter, so both are less suitable for households building around those platforms.
Will They Fit a Canadian Front Door?
Both models are designed around common North American deadbolt preparations, but “easy installation” does not mean every door is automatically compatible.
Before buying, measure:
- Door thickness: approximately 35–55mm
- Cross-bore diameter: approximately 38mm or 54mm
- Backset: approximately 60mm or 70mm
- Distance between the deadbolt and any handleset
- Space available for the larger interior battery housing
- Whether the door is wood or metal
- Whether a storm door leaves enough clearance
Older homes, modified doors, narrow frames, and decorative handlesets may need extra checking before purchase. If you rent or live in a condo, start with the broader apartment-friendly security camera guide before changing door hardware.
What About Canadian Winter?
eufy publishes an exterior operating range of approximately -30°C to 70°C for these locks. That does not guarantee identical battery life or performance in every Canadian winter.
Cold weather can affect rechargeable-battery runtime, and the actual temperature at an exposed front door may differ from the forecast. A covered Toronto porch and an exposed entrance in Winnipeg do not create the same conditions.
Before installing:
- Keep the rechargeable battery charged
- Respond to low-battery notifications early
- Keep the physical backup key accessible
- Confirm that the deadbolt moves freely before adding the smart lock
- Do not expect the motor to correct an improperly aligned or frozen deadbolt
- Protect the indoor assembly from moisture
- Check the lock after major temperature changes
Do not treat either lock as freeze-proof. For another power-focused home-security comparison, see battery vs wired security cameras.
Who Should Choose the eufy E330?
Choose the E330 if:
- You want the lower current purchase price
- Built-in 8GB storage is enough
- You do not need a separate indoor chime
- You prefer direct Wi-Fi instead of a chime bridge
- You want the core camera, fingerprint and keypad features
- You are installing one video smart lock rather than building a larger system
Who Should Choose the eufy S330?
Choose the S330 if:
- You want an included indoor chime
- You want expandable SD-card storage
- You expect more recorded front-door activity
- The additional detection features are useful
- You are comfortable paying more upfront
- You have a suitable indoor location for the chime and Wi-Fi bridge
Who Should Avoid Both?
- Renters who cannot replace the existing deadbolt
- Doors that do not match the required measurements
- Apple HomeKit or Matter-focused households
- Buyers who want a small traditional lock
- Users who do not want to recharge a large battery
- People who need professional alarm monitoring
- Doors with an existing alignment or freezing problem
Final Recommendation
The eufy E330 is the better value for most buyers. It provides the features that matter most—a 2K door camera, fingerprint entry, keypad access, app control, direct Wi-Fi, and built-in local storage—at a lower current price.
Choose the S330 when the included indoor chime, expandable SD-card storage, and additional detection options are worth the higher price. It is the more complete package, but it is not automatically the better purchase for every front door.
Before ordering either model, measure the door carefully, confirm Wi-Fi strength at the entrance, and check the latest Canadian price and bundle contents.

Does the E330 include an indoor chime?
It has built-in sound alerts, but it does not include the same separate indoor chime and Wi-Fi bridge supplied with the S330.
What size SD card does the S330 support?
