eufy Security Video Smart Lock E330, 3-in-1 Camera+Doorbell+Fingerprint Keyless Entry
Quick take
The eufy Security Video Smart Lock E330 is an all-in-one front door upgrade that pairs a fingerprint keyless deadbolt with a 2K video doorbell/camera and Wi-Fi remote access through the eufy Security app. It’s a strong fit for shoppers who want hands-free entry plus video visibility without installing separate components. The main buying caveat is setup and usability can feel confusing for some people, and some access scenarios still revolve around fingerprint control.
Pros and cons
Pros
- 3-in-1 combo: fingerprint smart lock plus 2K HD camera/video doorbell features.
- Fast access methods, including fingerprint and keypad/keys (varies by how you set up access).
- Remote control and live viewing from anywhere via the eufy Security app, with notifications and event history.
- Large rechargeable 10,000 mAh battery designed to reduce how often you buy or swap batteries.
Cons
- Some buyers report the app and initial setup can be difficult to figure out without clear guidance.
- Access for visitors may be less flexible if you primarily rely on fingerprint-based entry.
- Notification thumbnail previews may require temporary cloud thumbnail storage to work as described.
What buyers think
Buyer-review evidence for the eufy Security Video Smart Lock E330 points to a few consistent themes. Many reviewers describe fingerprint unlocking as quick and reliable, with real-world responsiveness that feels faster than older biometric locks they replaced. A noticeable portion of feedback also highlights the convenience of having the camera and doorbell features integrated into the lock, including remote viewing and reviewing events through the app. Installation and setup are often described as straightforward and fast, though there is also limited but clear evidence that some shoppers struggled with setup steps inside the app and getting their access methods configured correctly. Battery performance is generally viewed positively, with reports of strong charge retention across the first months of use.
What you get with the E330
The E330 is designed to replace your front door deadbolt with a single device that also watches the entry area. It combines:
- Fingerprint keyless smart lock for hands-free entry.
- A 2K HD camera with an f/1.6 lens intended for clearer visibility at night.
- Video doorbell functionality so you can see who is at your door.
- Wi‑Fi connectivity for app control, remote viewing, and notifications.
Fingerprint unlocking and access options
Unlocking is centered around fast fingerprint recognition, and multiple reviewers specifically call out improved reliability compared with older biometric locks they had trouble with. You also have multiple ways to manage access, including app control, voice assistant support (Alexa/Google Voice Assistant), a keypad option, and keys as a fallback.
Buyer-fit caution: while most shoppers likely appreciate biometric convenience, some setups and household access scenarios can be less convenient if you expect guests to lock or unlock with their own credentials immediately. If you often have friends, family, contractors, or frequent visitors, prioritize how you plan to add them and whether you want to lean on keypad and key options versus fingerprints.
Video doorbell and camera performance
The integrated camera is built for day-and-night visibility, using a 2K HD sensor and an f/1.6 lens. Reviewers who mention the camera tend to describe it as impressive, and many value the ability to view a live feed and review recorded events from anywhere in the app.
Storage and notifications
- Built-in storage: 8 GB is included for on-device storage.
- Notifications: push notifications with thumbnail previews are described as being dependent on thumbnail preview images being temporarily stored in the cloud.
Battery life and charging expectations
The E330 uses a rechargeable 10,000 mAh battery intended to power lock, camera, and doorbell features together. This is one of the more common “will I have to keep replacing batteries?” concerns with smart locks, and the majority of feedback trends positive on charge retention during early use. As with any battery-powered security device, battery life will still depend on how frequently the camera records, how active motion events are, and what notification settings you use.
Installation and smart home setup
Installation is designed to be quick and drill-free by supporting common US and Canadian deadbolt spacings, with an advertised install time of about 15 minutes without drilling. Several buyers say the lock was easy to install and that they were up and running quickly.
Potential friction point: limited but important feedback highlights that app setup can be confusing for some people, including difficulty with initial setup flow and adding access methods. If you prefer guided instructions or you want a very simple pairing experience, plan extra time for configuration and make sure you can follow the on-screen prompts.
Who it’s best for
- Front-door security upgraders who want a single-device solution instead of installing a separate video doorbell and a separate smart deadbolt.
- Households that prioritize quick entry and plan to use fingerprint unlocking as the primary method.
- Remote-check users who want to see who is at the door and manage access from anywhere through the eufy Security app.
- Busy entryways where battery convenience matters, since the device is powered by a large rechargeable 10,000 mAh battery.
Who should avoid it or consider alternatives
- Buyers who want the simplest possible setup and are worried about app pairing and access configuration.
- Homes that frequently need guest-based lock/unlock control where visitors must reliably access without fingerprints (prioritize keypad or key-based workflows).
- People who don’t want any cloud-dependent behavior for notification previews, since thumbnail preview behavior is described as requiring temporary cloud storage.
Price and value
The E330 is positioned as an all-in-one smart lock plus video doorbell/camera package. That bundled approach can be good value if you were already planning to buy both a smart deadbolt and a separate door camera. If you only need one of the two features (for example, just keyless fingerprint entry or just a door camera), you may be better served by a more single-purpose option to avoid paying for features you will not use.
Verdict
The eufy Security Video Smart Lock E330 is a compelling front door upgrade for shoppers who want fingerprint keyless entry plus a 2K video doorbell/camera in one install. Buyers who value fast and reliable biometric unlocking, remote app control, and integrated visibility at the door tend to be the most satisfied. If you anticipate complicated household access, or you want a very guided pairing experience, treat setup and access configuration as a key decision factor before you buy.
