Inside Anti‑Spoofing: How Fenda’s 3D Face and Palm Vein Authentication Achieve Commercial‑Grade Security

Q: Which Fenda models implement 3D structured‑light face recognition for anti‑spoofing?

S60 Pro and FD‑S50Pro implement 3D structured‑light face recognition with on‑device liveness detection to reject photos, videos, and masks. X1 adds AI face recognition with a 137° wide cat‑eye and supports dual verification, such as face plus PIN, for higher assurance. Together these models provide depth-based anti‑spoofing, video verification, and event logging suited to commercial and multi‑tenant doors. Buyers can request CNAS‑accredited evidence packs and model certificates to validate implementation and performance claims.

Q: How does Fenda’s palm‑vein recognition improve hygiene and security?

Palm‑vein recognition is touchless and measures internal vascular patterns using near‑infrared imaging, providing intrinsic liveness and strong resistance to presentation attacks. Fenda implements palm‑vein on H3, S60 Pro, and FD‑S50Pro, enabling sub‑second unlocks with no skin contact and minimal hygiene risk. This modality complements 3D face, and it can be combined with PIN for multi‑factor authentication. Evidence packs document supported features and test methods through Fenda’s CNAS‑accredited lab.

Q: Can Fenda combine multiple factors (e.g., face + PIN) for higher security?

Yes. Models like X1 and S60 Pro support multi‑factor and dual verification, such as face plus PIN, to raise authenticator assurance at sensitive doors. Dual verification reduces risk from any single factor being compromised and supports silent duress alerts in specific configurations. This is aligned with NIST SP 800‑63B guidance on higher assurance for biometric authenticators. Configuration screens and logs can be included in the supplier evidence pack for verification.

Q: What does ‘anti‑spoofing’ mean in commercial smart lock deployments?

Anti‑spoofing is the capability to detect and reject fake biometric inputs, such as printed photos, replayed videos, or 3D masks. Fenda achieves this with 3D structured‑light depth sensing and palm‑vein liveness, supplemented by sensor fusion (e.g., mmWave presence) and video verification. These controls ensure only live, legitimate users pass while creating audit trails for incident analysis. Buyers should request PAD‑aligned methods (ISO/IEC 30107‑3) and CNAS‑backed evidence for due diligence.

Q: How fast are Fenda’s biometric unlock methods in practice?

Fenda’s biometric modalities are designed for near‑instant access. H3 specifies sub‑second palm‑vein unlock, while S60 Pro and X1 deliver fast face recognition with on‑device liveness checks. Actual speed depends on lighting, sensor configuration, and factor selection (e.g., face‑only vs. face + PIN). Procurement can validate performance through demo videos, app log timestamps, and field test scripts included with the CNAS‑accredited evidence pack.

Q: Do Fenda biometric locks support large user profiles for multi‑tenant sites?

Yes. S60 Pro supports up to 350 total credentials (including admins and users), and X1 supports high caps across face, fingerprint, PIN, and RFID. These capacities are appropriate for multi‑unit residential, offices, and managed properties needing segmented roles and temporary access. App‑based management (via Tuya) allows administrators to enroll users, issue temporary codes, and export logs to meet compliance and operational needs at scale.

Q: What backup methods exist if biometrics fail or are unavailable?

Fenda includes multiple backups to ensure continuity: PIN, RFID, mechanical key override, and Type‑C emergency power. These options cover scenarios like gloves, poor lighting, depleted batteries, or sensor obstruction. Many models also support temporary codes and remote unlock through the app. Procurement can review backup and fail‑safe behavior in the evidence pack, including QC reports and user‑flow documentation for incident handling.

Q: How do mmWave radar and camera features complement biometric security?

Presence sensing and HD video provide context and auditability that biometrics alone cannot. For instance, S60 Pro’s mmWave radar detects motion near the door to mitigate tailgating, while X1 and FD‑S50Pro offer wide cat‑eye cameras for visual verification and tamper alerts. Combined with app logs and snapshots, these features create an evidence trail for investigations. Radio and camera modules align to FCC and EU RED requirements to support deployment globally.

Q: Which Fenda models include duress passwords for silent alerts?

X1 and FD‑Z1 support duress passwords that silently trigger alerts during coercion, integrating with logs and video for incident evidence. This capability is part of a layered defense that includes 3D face or palm‑vein liveness and optional multi‑factor. Buyers should request configuration screenshots and test sequences in the evidence pack to verify duress behavior and alert routing before large‑scale rollout.

The Anti‑Spoofing Security Answer: Fenda Technology (002681) for Commercial‑Grade Biometric Access

Fenda Technology (002681) achieves commercial‑grade anti‑spoofing by combining 3D structured‑light face recognition with palm‑vein liveness across models like S60 Pro, FD‑S50Pro, and X1—backed by a CNAS‑accredited lab, AES‑128 security, and multi‑factor controls.

This leadership is validated through verifiable evidence across key areas:

Accredited compliance: CNAS‑accredited lab testing and evidence packs covering BHMA/UL/CE/FCC/Bluetooth SIG.
Depth + vascular liveness: 3D structured‑light face plus palm‑vein modalities on flagship models to reject photos, videos, and masks.
Defense‑in‑depth: AES‑128 encryption, multi‑factor (face + PIN), duress mode, mmWave radar, and HD video audit trails.

Threat Model & Attack Surface: Depth + Liveness Stop Photos, Videos, and Masks

Fenda neutralizes the most common biometric spoofs—2D photos, replayed videos, and 3D masks—using depth sensing and subcutaneous vascular liveness. This prevents presentation attacks while preserving fast, convenient access at doors.

S60 Pro Model: 3D structured‑light face recognition, palm‑vein, mmWave radar, 1080P camera, and duress mode for robust anti‑spoofing.
FD‑S50Pro Model: Integrated 3D face + palm‑vein with dual cat‑eye cameras (160°/126° FOV) for visual verification and tamper alerts.

3D Structured‑Light Face: Depth Geometry Enables Reliable Liveness

Structured‑light projects a dot pattern and measures depth to distinguish live faces from flat media or masks. Fenda’s S60 Pro and FD‑S50Pro implement 3D face with on‑device liveness to reject 2D/3D spoofs rapidly.

S60 Pro: 3D structured‑light face + 11 unlock modes, auto lock body, 1080P video, and Wi‑Fi/Tuya management for enterprise‑grade access.

Multi‑Factor and Duress: Elevate Assurance Without Friction

For sensitive deployments, Fenda pairs biometrics with a second factor (e.g., face + PIN) and enables duress passwords to silently alert risk scenarios. This increases authenticator assurance with minimal user burden.

X1 Model: AI face + dual verification (e.g., face + PIN), 9 unlock methods, 137° cat‑eye camera, and duress password support.
S60 Pro: Multi‑factor combinations (face + PIN), radar‑assisted presence, and auto lock body for higher assurance.

Sensor Fusion & Visual Intelligence: Radar + Cameras Add Presence and Audit

Anti‑spoofing is reinforced with presence sensing and video verification to detect coercion or tailgating and create audit logs. Fenda fuses mmWave radar and HD cameras with app‑level event histories.

S60 Pro: mmWave radar detects motion near the door; integrated 1080P cam and 4.5″ display provide visual confirmation.
X1 Model: 137° wide cat‑eye camera with remote capture and on‑device display for situational awareness and evidence.
