Overview
Next-Gen AI Face Recognition & Multi-Modal IoT Smart Lock PCBA
KEYPLUS HXJ61E / HXJ29E Commercial Smart Lock Mainboard
The KEYPLUS HXJ61E / HXJ29E is an industrial-grade IoT smart lock PCBA engineered for hotels, multi-family apartments, student dormitories, and commercial campus access control. Supporting multi-modal credentials—including 3D dynamic face recognition, semiconductor fingerprint, RFID card, PIN code, and mobile BLE—it combines sub-0.5s biometric validation, ultra-low standby power consumption (<90 µA), modular IoT expansion (BLE, Sub-1G, NB-IoT, Wi-Fi), and open RESTful API/SDK toolkits for rapid SaaS, PMS, and BMS integration.
Pain Points & Challenge
Overcoming Access Loopholes and Infrastructure Bottlenecks in Commercial Spaces
- Subletting & Identity Verification Loopholes: Public housing, co-living units, and student housing suffer from illegal key duplication, passcard sharing, and proxy check-ins. KEYPLUS solves this with dynamic binocular 3D face verification pushed directly from cloud to lock, eliminating unauthorized credential transfers.
- Complex Wiring & Network Fragmentation: Running Ethernet lines across hundreds of door units incurs massive infrastructure expenditures and downtime. KEYPLUS provides modular networking flexibility—choose standalone BLE, ultra-long-range Sub-1G gateways (up to 64 locks per gateway), or direct NB-IoT for zero door recabling.
Key Capabilities & Benefits
3D Dual-Camera Facial Recognition Module
- Feature: Binocular infrared (IR) sensor with dynamic liveness detection algorithms and dedicated biometric hardware compute.
- Advantage: Verifies registered faces in under 0.5 seconds while rejecting printed photos, mobile screen playback, and 3D silicone mask spoofs in pitch darkness, backlight, or direct sun.
- Benefit: Delivers true frictionless, hands-free entry for residents and guests while assuring building operators of indisputable identity compliance.
Dynamic Multi-Modal Credential Management
- Feature: Supports up to 889 shared access keys across 3D Face (100 faces), semiconductor fingerprint, IC/Mifare cards, and algorithmic time-limited passcodes.
- Advantage: Remote issuance of one-time codes, recurring maintenance PINs, and instant single-click credential revocation without wiping user profiles.
- Benefit: Eliminates physical key and card handovers, minimizing front-desk staffing costs and streamlining turnover for rental properties.
Industrial Hardware Ruggedness & Telemetry Sensing
- Feature: Built-in ±15KV air discharge ESD immunity, latch bolt position switches, interior/exterior opening sensors, and anti-pry tamper loops.
- Advantage: Real-time hardware health telemetry, instant door-ajar alerts, forced-entry notifications, and battery level tracking continuously pushed to the server.
- Benefit: Prevents unmonitored security blind spots and slashes on-site maintenance cycles with proactive diagnostics.
