EZVIZ DL50FVS Smart Lock: Face ID, Video and Specs

The EZVIZ DL50FVS is a smart door lock that opens with your face, fingerprint, code, key or phone. It also works as a video doorbell with a screen inside the door. It suits flats and houses in Maputo where people come and go all day: family, domestic staff, deliveries. This guide covers what it does, the official specifications, and the points to check before you fit it to your door.

What the DL50FVS does

On the outside there is a slim aluminium panel with a camera and a 3D face recognition sensor. You walk up, it recognises you, and the door opens without touching anything. On the inside a 4-inch colour screen shows who is outside, so it replaces the peephole, and you can talk to the visitor or answer the call from your phone in the EZVIZ app when you are away.

The lock also watches the door. A radar sensor notices someone lingering in front of it, the camera records short clips to its built-in storage, and the app tells you who opened the door and when.

Everything is managed from the EZVIZ app on your phone. You add or remove users, create temporary codes for guests, check the unlock history and get an alert when someone rings or waits at the door. If you already use EZVIZ cameras at home, the lock sits in the same app, so the door and the cameras are in one place.

Official specifications

From EZVIZ's product page for the DL50FVS:

• Unlocking methods: face recognition, fingerprint, passcode, mechanical key, Bluetooth key through the EZVIZ app, temporary codes and remote unlocking.
• Face recognition: dual-lens 3D depth sensing that accepts only real faces, not photos or videos, in under 1.5 seconds in the manufacturer's tests, for users from 1.2 to 2 metres tall. Face models are processed and stored on the lock itself.
• Capacity: up to 50 users, 50 faces, 50 fingerprints and 50 passcodes.
• Screen and video: 4-inch colour screen inside, two-way video call, infrared night vision up to 2 metres, built-in local storage for clips.
• Battery: 5,000 mAh rechargeable lithium battery, up to 4 months between charges based on about ten face unlocks and a few minutes of video a day. A Type-C port takes a power bank in an emergency.
• Connectivity: 2.4 GHz Wi-Fi and Bluetooth.
• Alarms: siren if the panel is forced off, tamper alarm, low battery warning, and lockout after five wrong passcodes.
• Rating: IP52, operating from minus 10 to plus 55 degrees Celsius.

Who it suits

• Families: no more keys for every child, and you see in the app when they arrive home.
• Homes with domestic staff: give the empregada or the gardener their own fingerprint or a code limited to working days, and remove it in seconds when needed.
• Short-stay flats: send a temporary code to a guest instead of meeting them with a key.
• Small offices: know who opened the door first in the morning without installing a full access control system.

What to check before you buy

• Your door. EZVIZ makes the DL50FVS with two lock bodies, 5085 and 6068, for different door types; the 6068 version is listed for doors 40 to 120 mm thick. We measure the door and the existing lock before ordering.
• Rain and sun. IP52 means protection against dust and dripping water, not driving rain. On an exposed outside door, the lock needs a porch or canopy above it. Many Maputo flats have the lock inside a corridor, which is ideal.
• Wi-Fi at the door. The lock uses 2.4 GHz Wi-Fi. If the router is far away, we add an access point so the video and alerts are reliable.
• Power cuts. The lock runs on its own battery, so a power cut does not lock you out. Without internet it still opens with face, fingerprint, code or key; only the remote features wait for the connection.

Smart lock, cameras and alarm

A smart lock controls one door. For the whole home, combine it with cameras on the outside and a home alarm system that protects the windows and other doors. Offices that need several doors, attendance reports and links to CCTV are better served by a proper access control system, as we explain in how to choose access control for your office.

Frequently asked questions

What happens if the battery of the EZVIZ DL50FVS runs out?

The app warns you well before. If it does run flat, connect a power bank to the Type-C port outside and open with your usual method, or use the mechanical key.

Does the DL50FVS work without internet?

Yes. Face, fingerprint, passcode, key and Bluetooth unlocking work locally. Remote unlocking, video calls on your phone and notifications need Wi-Fi.

Can a photo of my face open the lock?

No. The 3D depth sensor checks that it is a real face, and EZVIZ states that photos and videos are rejected.

Can you install it on my existing door?

In most cases yes, after we check the door thickness and the lock body. Some doors need minor carpentry, which we tell you about before ordering.
