Streamlining Guest Management :Designed specifically for Airbnb hosts and property managers, the BKFSD eliminates key exchanges while providing superior control. Generate unlimited one-time PINs that expire after checkout, or implement rolling codes for long-term tenants. The anti-peep keypad scrambles number positions after each use, while the tamper-proof audit log records every entry attempt with accompanying video clips - perfect for resolving security deposit disputes.

Architectural-Grade Durability: The lock's monobloc aluminum body (3.3kg) withstands 1000N of brute force attacks, exceeding ANSI Grade 1 standards. We've patented the self-sealing gasket system that prevents weather damage to internal components - a critical feature for beachfront properties or mountain cabins. The dual-power system (8 AA batteries + emergency USB-C) ensures 18-month operation, with low-battery alerts sent to both guests and managers.

Operational Intelligence:Integrated with major PMS systems via API, the BKFSD automatically syncs with booking calendars to adjust access permissions. The noise-canceling intercom allows clear communication even in noisy urban environments, while the adaptive backlighting ensures visibility from any angle during night check-ins. Our proprietary door sense technology detects improper closing attempts, preventing accidental lockouts that generate 30% of hospitality service calls.

Beyond conventional fingerprint and password entry, we've incorporated advanced palm vein recognition and facial authentication technologies that achieve military-grade accuracy (0.001% false acceptance rate). The integrated 1080p cat-eye camera doesn't just capture footage - it utilizes AI motion detection to distinguish between humans, pets, and vehicles, storing compressed 24/7 footage efficiently for 7 days without requiring cloud subscriptions.
