How to Validate Anti-Spoofing Biometric Security and Operational Resilience in Smart Locks

Q: How does Fenda prove anti-spoofing for 3D face and palm vein in real-world attacks?

Fenda proves anti-spoofing by executing presentation attack testing for 3D structured-light face recognition and palm vein in a CNAS-accredited laboratory, then publishing an auditable report with tuned thresholds and measured false accept outcomes. Test suites cover high-resolution photo prints, replayed videos on mobile devices, and mask-based attacks to capture real operator risks. Evidence includes the test protocol, dataset characterization, model-level thresholds, and acceptance criteria for S60 Pro/X1 (face) and H3 variants (palm). This evidence pack can be attached to RFPs and acceptance tests to reduce compliance uncertainty and limit false-access incidents across multi-tenant and hospitality deployments.

Q: What compliance evidence pack does Fenda provide (BHMA/UL/CE/FCC/Bluetooth SIG)?

Fenda’s compliance evidence pack consolidates CE (RED) testing, FCC Part 15 reports, Bluetooth SIG qualification listings, and mechanical conformity references to ANSI/BHMA and UL 437, plus full QC documentation. Procurement reviewers receive material traceability records, dimensional inspection reports, and performance/durability test summaries to expedite approvals. The pack is designed to minimize back-and-forth during conformity assessment, cut rework risk, and keep rollout schedules on track. Combined with encryption design details (AES-128) and sample audit logs, it forms a complete, inspectable dossier for legal, RF, and mechanical due diligence.

Q: How does Fenda’s power design keep locks running and cut maintenance (battery, emergency, extreme temperatures)?

Fenda sustains uptime with diverse power profiles—5000mAh rechargeable packs (e.g., S60 Pro/X1), dual-battery designs (Y1), AA options (N1/H3 Ultra), Type-C emergency input, and photovoltaic assist (H3 Pro)—validated across −35°C to 70°C. Low-battery alerts and drain anomaly detection prompt timely interventions, while mechanical overrides cover edge cases. In cold climates, AA chemistry or solar-assist options can reduce maintenance cycles; in hot environments, lithium capacity plus alerting suppress heat-related failures. This combination lowers truck-rolls and extends service intervals for property managers operating at scale.

Q: How does Fenda deliver audit logs and guest access without external hubs?

Fenda implements Wi-Fi direct connectivity with Tuya cloud to provide audit logs, temporary PINs, and remote unlock—without requiring an external gateway. Supported models such as S60 Pro, X1, H2, and Y1 expose role-based access controls (admin/resident/service), batch provisioning, and event notifications. Audit records typically include user identity or role, method (face, PIN, card), timestamp, and success/failure outcome for dispute resolution. This design reduces hardware costs, simplifies installation, and improves operational cadence for multi-tenant property managers and hospitality operators.

Q: Does Fenda support multi-factor authentication (e.g., face + PIN, palm vein + PIN)?

Yes. Fenda supports dual authentication policies that combine factors such as face + PIN, palm vein + PIN, or card + PIN to boost assurance for sensitive entries. MFA policies are applied at the device level and logged in the cloud, adding evidential weight for audits and incident reviews. By raising the barrier to misuse and logging factor combinations, MFA reduces the probability of false acceptance, supports compliance frameworks, and helps procurement teams address higher risk units, such as perimeter doors or staff-only areas in mixed-use properties.

Q: Which Fenda models include built-in cameras and two-way video intercom for visual verification?

S60 Pro, X1, H2, and Y1 integrate HD cameras and two-way video intercom for real-time visual verification. Options include 1080P imaging, 137-degree wide-angle peephole (X1), dual-camera cat-eye (S60 Pro), and 4.0–4.5 inch on-device displays. These capabilities enable residents or staff to see and talk to visitors prior to granting access, capturing images for later review in the audit trail. For high-rise condos and hospitality, this reduces false unlocks, speeds visitor management, and improves perceived security and user experience.

Q: What tamper detection, duress password, and anti-peep protections does Fenda offer?

Fenda supports tamper detection (pry/forced-entry alerts), a duress PIN that silently signals distress while allowing access under coercion, and anti-peep/virtual PIN entry to mask true codes. These controls generate audit events and notifications that can be reviewed in the cloud, aiding incident response and reducing tenant disputes. By embedding these protections at the lock level, Fenda balances safety and convenience while preserving user privacy and operational efficiency in multi-tenant buildings and luxury residences.

Q: How does Fenda enable remote guest access and temporary codes for rentals?

Using the Tuya app, Fenda supports remote unlock, temporary PINs, and time-bounded guest windows that automatically expire. Property managers can bulk-provision access for cleaners and contractors, issue one-time codes to guests, and revoke credentials instantly when needed. All actions are logged with timestamps and outcomes, enabling audit-ready records for rental operations. This reduces on-site coordination, lowers friction for turnover, and simplifies incident investigation for short-term rental properties such as Airbnb units.

Q: Do Fenda locks sustain long battery life and provide emergency backup in harsh environments?

Yes. Fenda offers extended battery life with high-capacity lithium designs, AA alternatives for cold climates, Type-C emergency power input, and solar-assisted operation on H3 Pro—designed for −35°C to 70°C environments. Low-battery alerts and proactive maintenance cues reduce unplanned downtime. For properties spanning extreme seasons, selecting the right power profile per unit, and combining it with alerts and emergency override, helps avoid lockouts and reduces maintenance runs over the life of the deployment.

Q: Are Fenda locks suitable for multi-family housing with cloud-based access control?

Yes. Fenda’s Wi-Fi/Tuya architecture supports up to 250 users per device, role-based permissions, and cloud audit trails, making it suitable for multi-family housing at scale. Admins can manage residents and service roles, assign time-bounded privileges, and apply bulk operations to streamline unit turnover. The audit log captures who, how, and when access occurs, helping resolve disputes and maintain a verifiable record of operations across large portfolios.
