Ezviz Smart Door Lock | Video Call | Surveillance | Face & Palm Vein | DL20FVS Plus
The EZVIZ DL20FVS Plus (CS-DL20FVS Plus) is a lever-handle smart door lock that combines 3D face recognition, palm vein recognition and a built-in video door viewer with a 4-inch indoor screen. It can be opened by face, palm vein, fingerprint, passcode, mechanical key, Bluetooth key in the EZVIZ App, temporary codes or remote unlocking, and it runs on a 5,000 mAh rechargeable lithium battery.
3D face recognition: Stand less than 1 m in front of the lock and it recognises your face in 1 second or less (EZVIZ lab data), for users between 1.2 m and 2 m tall. No key or code is needed.
Palm vein recognition: Hold your palm facing the sensor at 15–25 cm to unlock without touching anything (EZVIZ recommends about 10 cm for children). EZVIZ notes that conditions such as strong sunlight can affect recognition.
Built-in video door viewer: A front camera with a 150° diagonal view and a 4-inch IPS indoor screen (480 × 800, not touch) let you see who is outside without opening the door or using your phone. IR night vision reaches up to 2 m.
Video calls and alerts in the EZVIZ App: Over 2.4 GHz Wi-Fi the lock sends real-time notifications, lets you video-call visitors (with a voice-change option) and unlock remotely. Wandering detection warns you when someone stays in front of the door.
Security features: An anti-tamper alarm, anti-peeping passcode, anti-test locking and privacy mode protect against misuse. Biometric data is processed locally on the lock, and EZVIZ states that data is end-to-end encrypted.
Automatic locking: The 6068 automatic mechanical detection lock body locks the door after it closes, so you do not need to lock it by hand. A C-level cylinder takes the mechanical key for backup access.
Battery: The 5,000 mAh rechargeable lithium battery lasts 4–5 months per charge according to EZVIZ, measured with Wi-Fi off (Bluetooth only) and about 10 openings a day. A Type-C port allows emergency charging.
Who it's for / Works with
Doors 40–120 mm thick (with the 6068 lock body). The lock works with the EZVIZ App, and EZVIZ lists Google Assistant and Amazon Alexa support (via OTA update). Available without installation or with installation for a compatible door.
Good to know
Battery life is shorter when the lock stays connected to Wi-Fi. IP52 means protection against dust and dripping water; it is not a waterproof rating. The lock locks the door automatically, but it does not open the door by itself.
