How Do I Set Up the eufy Video Smart Lock?

Problem Description

You are installing the eufy Video Smart Lock on your front door. The lock combines a smart deadbolt with a built-in camera and fingerprint reader on the exterior keypad. Check that your door fits the lock requirements (door thickness 1-3/8" to 2", standard bore hole). This guide covers compatibility, installation, and app setup.

Why This Happens in Real Homes

The eufy Video Smart Lock combines a deadbolt, a fingerprint reader, and a built-in doorbell camera in one unit, so setup covers three things: a solid mechanical install with the deadbolt calibrated, fingerprint enrollment, and a 2.4GHz WiFi connection for the camera and app. The camera side makes strong door-side WiFi more important than on a plain lock.

Install the lock so the deadbolt throws freely and run its calibration, enroll fingerprints capturing each finger at several angles, and connect it to a 2.4GHz network (not 5GHz) with good signal at the door. Enable the doorbell and camera features in the eufy Security app, keep the battery charged, and install any firmware. A clean mechanical install plus strong 2.4GHz coverage is what makes both the lock and its camera reliable.

Tools & Requirements

Step-by-Step Solution

1

Check compatibility before installation

The eufy Video Smart Lock (model E330) replaces your existing deadbolt. It requires a standard door thickness (1-3/8 to 2 inches) and a standard US deadbolt bore (2-1/8 inch diameter hole, 1-inch edge bore). The lock includes a built-in 2K camera and fingerprint reader on the front, and a keypad on the inside. Remove your existing deadbolt and check the door prep dimensions before purchasing.

Install the lock hardware

Remove the existing deadbolt (inside and outside pieces). Install the eufy lock mounting plate on the inside using the existing bolt hole. Thread the lock cable through the door hole. Attach the exterior assembly (camera + fingerprint reader + keypad) to the front of the door. Secure the interior assembly onto the mounting plate. The lock auto-adjusts to your door thickness. Test the deadbolt operation by extending and retracting it manually using the interior thumb turn before powering on.

3

Set up in the eufy Security app

Open the eufy Security app. Tap + > Add Device > Video Smart Lock. The app connects to the lock via Bluetooth. Follow the prompts to connect the lock to your 2.4GHz WiFi (required for remote access and video features). Set up your admin PIN code on the keypad. The lock also supports fingerprint unlock — register up to 20 fingerprints. The built-in camera connects to the app for remote video monitoring of your door.

4

Configure auto-lock and unlock features

In the eufy app, go to the lock settings. Enable Auto-Lock to automatically lock the deadbolt after a configurable delay (15 seconds to 5 minutes) when the door closes. Enable Auto-Unlock to unlock the door when your phone approaches (uses Bluetooth proximity). Set up unique PIN codes for family members and guests — you can create temporary PINs that expire after a set time, useful for house cleaners, dog walkers, or Airbnb guests.

5

Use the built-in camera features

The front-facing 2K camera works like a video doorbell. In the eufy app, you can view a live feed, get motion alerts when someone approaches, and use two-way audio to speak with visitors. The camera records motion events to local storage (HomeBase or built-in). Unlike a separate doorbell camera, this camera is integrated into the lock — so you see who is at the door and can unlock remotely from the same app view.
