Building access system with 3D facial unlock.

A real estate technology firm needing an outdoor, 4G-connected biometric intercom system for apartment complexes.
Ensuring secure, anti-spoofing facial recognition in varying outdoor lighting conditions (from direct sunlight to pitch black) while maintaining a reliable 4G VoLTE connection.
The Unisoc SC9863A (Octa-core 4G LTE SoC) provides the cellular backbone and processing power. It interfaces with a dual-lens camera module (RGB + Infrared).
We developed a custom Android ROM stripped of all consumer apps. To defeat 2D photo spoofing, we implemented an edge AI algorithm that analyzes both the RGB and IR camera streams concurrently, analyzing depth and thermal signatures. The SC9863A's hardware ISP was custom-tuned to handle extreme WDR (Wide Dynamic Range) for backlit scenarios. VoLTE SIP stacks were integrated for instant audio calls to residents.
Face recognition < 0.5s with a 0.01% False Acceptance Rate. Functions perfectly in complete darkness via IR illumination. SIP calls connect in under 2 seconds.
