Why Traditional 2D Face Unlock is Obsolete

Don't compromise your brand reputation with vulnerable security. Upgrade to 3D sensing.

Presentation Attacks

2D cameras are easily fooled by high-res photos or phone screens. ToF perceives depth, instantly rejecting flat surfaces.

Lighting Constraints

RGB cameras fail in low light or require blinding white LEDs. ToF uses Active IR, working perfectly in 0-lux pitch darkness.

Privacy Concerns

Users worry about cameras. ToF processes only depth data, ensuring GDPR compliance without storing identifiable color images.

True 3D Depth Sensing Technology

1

Liveness Detection

Our algorithm analyzes 30,000+ depth points to confirm facial curvature, effectively blocking 2D masks, photos, and video attacks.

2

Wide FOV for All Heights

Vertical FOV optimized for smart locks. Detects faces from 1.2m (children) to 2.0m (tall adults) at a comfortable distance.

3

Ultra-Low Power Consumption

Deep sleep architecture with fast wake-up (<0.5s). Designed to maximize battery life in AA/Li-ion powered locks.

4

Works in Direct Sunlight

Engineered for outdoor reliability. With resistance up to 100K Lux, our ToF modules ensure consistent performance in direct sunlight, significantly outperforming traditional structured light.

Frequently Asked Questions

Key insights on security, reliability, and integration of 3D ToF Face ID solutions.

Is 3D ToF face recognition reliable for residential smart locks?
Yes, 3D ToF face recognition is a reliable authentication method for residential smart locks, especially in environments with varying lighting conditions. Unlike 2D camera-based solutions, ToF cameras capture real depth information of a user’s face, which improves recognition accuracy and reduces false acceptance caused by photos or videos. This makes ToF particularly suitable for apartment doors, villas, and premium residential access systems.
Can ToF-based face recognition replace fingerprint sensors in smart locks?
ToF-based face recognition cannot fully replace fingerprint sensors, but it can effectively complement or partially substitute them in smart lock systems. Fingerprint recognition remains cost-effective and energy-efficient, while ToF face recognition offers contactless access and better usability when hands are occupied or fingers are wet. As a result, many smart lock manufacturers adopt a multi-factor authentication design, combining ToF face recognition, fingerprint, and PIN codes.
How does ToF face recognition perform in family environments with children?
ToF face recognition performs well in multi-user household environments, including families with children, when properly calibrated. Because ToF cameras rely on 3D facial structure rather than surface texture, they are less sensitive to skin condition and minor appearance changes. This makes them suitable for homes with multiple family members of different ages and heights. Periodic facial data updates may be required as children grow.
Where is face recognition data stored in ToF-based smart locks?
In most ToF-based smart lock systems, facial recognition data is stored locally on the device rather than in the cloud. Typically, only encrypted biometric templates are stored in secure hardware such as a dedicated MCU or trusted execution environment (TEE). This approach helps meet privacy and data protection requirements while allowing the smart lock to function offline without relying on cloud connectivity.
