## Description

See who is at your front door and choose a convenient way to unlock it with the eufy Security Video Smart Lock E331. Its 2K camera and fingerprint access bring video monitoring and keyless entry together in one smart deadbolt, with app-based remote access for checking activity when you’re away.

Use the fingerprint reader for everyday entry, or choose the keypad, app, voice control, or a physical key. A countdown auto-lock adds a hands-off way to secure the door after you leave.

## How it fits

E331 is designed for front, entry, apartment, office, and other exterior doors. It combines a doorbell camera with a deadbolt, so you can view visitors and manage access from the eufy Security app instead of treating video monitoring and locking as separate tasks. Real-time activity notifications help you stay informed about the entrance, while the camera’s 2K resolution and f/1.6 lens support a clearer view, including after dark.

For a standard US deadbolt installation, the door needs a crossbore diameter of 38 mm or 54 mm, a 60 mm or 70 mm backset, a 25.4 mm hole, and a thickness of 35 mm–55 mm. The handleset location must be greater than 45 mm. The lock is intended for wood or metal doors, and installation takes about 15 minutes on most standard US deadbolt setups without drilling. Check these measurements against your door before installation.

## Pros

Fingerprint recognition gives household members a quick keyless entry method, while PIN access and two physical keys provide other ways to unlock. The app supports remote access and notifications, and Alexa and Google voice assistant control add hands-free options. The rechargeable 10,000 mAh battery powers the lock and video features, a low-battery notification is sent when the charge falls below 10%.

Buyer feedback frequently appreciates the camera and fingerprint access, while experiences with scanning, locking and unlocking, battery runtime, and Wi-Fi vary. Some buyers also raise concerns about the protective layer peeling. These reports offer a useful perspective on everyday use, alongside the documented access and monitoring features.

## What to clarify

**Where are recorded videos stored?** Video is stored locally in the built-in 8GB eMMC. If you use cloud features such as thumbnail previews in push notifications, those previews may be sent to the cloud to provide that feature.

**What happens if the battery runs out?** You can power the lock through the port on the exterior assembly. The lock also includes two physical keys, with the key cylinder beneath a cover.

**Can storage be expanded?** With HomeBase 3, local storage can be expanded up to 16TB, additional storage drives are sold separately. HomeBase 2 is not supported.

## Is it worth it?

E331 is a practical choice for a front-door setup where video awareness and flexible entry matter together. Its camera, app access, fingerprint reader, backup key options, and countdown auto-lock give households several ways to check the entrance and manage daily comings and goings from a single lock.
