The DL50FVS Plus works as a multifunctional security system.

This review explores the design, features, security performance, and overall value of the EZVIZ DL50FVS Plus to help you understand whether this AI-powered smart lock is the right choice for modern homes.
EZVIZ DL50FVS Plus Design and Build Quality
The EZVIZ DL50FVS Plus features a modern and premium appearance designed to match contemporary residential doors. Its aluminum alloy construction provides a strong yet elegant look, while the ergonomic handle design improves daily usability for family members of different ages.
The smart lock uses a mechanical lock body type 5085 and supports doors with compatible thickness ranges, making it suitable for many residential applications. The device is also designed to withstand different environmental conditions with operational support between -10°C and 55°C.
From a design perspective, EZVIZ focuses on balancing security and aesthetics. The lock does not only protect your home but also enhances the appearance of your entrance area.
Advanced AI Face Recognition Technology
One of the strongest features of the EZVIZ DL50FVS Plus is its AI-powered 3D face recognition system.
The smart lock uses EZVIZ AI 3D modeling and recognition technology to identify registered users quickly and accurately. According to EZVIZ laboratory data, the unlocking response can be completed in less than one second, while the false acceptance rate is designed to remain extremely low.
This technology provides several advantages:
- No need to carry physical keys
- Faster entry for authorized users
- Works with different hairstyles and accessories
- Supports recognition in different lighting conditions
- Helps prevent unauthorized access attempts
Compared with traditional fingerprint locks or password-based systems, facial recognition provides a more natural and contactless experience.

Palm Vein Recognition: More Security Without Touching the Scanner
Another unique feature of the DL50FVS Plus is palm vein recognition technology.
Palm vein authentication analyzes the vein patterns inside the user’s palm, offering an additional biometric unlocking option. This can be useful for children, elderly family members, or situations where fingerprints may not work effectively.
The system supports multiple unlocking methods, allowing users to choose the most convenient option for different situations.
Available access methods include:
- Face recognition
- Palm vein recognition
- Fingerprint
- Password
- Bluetooth key through the EZVIZ App
- Temporary access codes
- Mechanical key
This flexibility makes the smart lock suitable for families, rental properties, offices, and smart home environments.
Built-In Camera and Smart Door Monitoring Features
The EZVIZ DL50FVS Plus is more than just a door lock. It includes a built-in camera system that allows homeowners to check visitors before opening the door.
The device offers:

These features allow users to see and communicate with visitors without directly opening the door.
For families concerned about package deliveries, unknown visitors, or front-door activity, this feature provides an additional layer of awareness.

Smart Security Alerts and Anti-Theft Protection
Security is the main purpose of any smart lock, and the EZVIZ DL50FVS Plus includes several protection technologies.
The device provides:
- Anti-tamper alarm
- Incorrect password protection
- Anti-peeping password technology
- Low battery notifications
- Real-time activity alerts
- Human presence detection
The built-in 5.8 GHz radar human presence sensor helps detect people near the door area, allowing users to receive notifications when unusual activity occurs.
The smart lock also uses local data processing and encryption technology to improve privacy protection. EZVIZ states that biometric information is processed locally with security protection measures.
Battery Performance and Smart Home Convenience
Power management is an important factor for smart locks. The EZVIZ DL50FVS Plus comes with a 5,000 mAh rechargeable lithium battery.
Under specific usage conditions, the battery can support several months of operation before requiring a recharge. The actual battery duration may vary depending on network connection, usage frequency, and environmental conditions.
The Type-C emergency charging feature also provides convenience when the battery level becomes low.
