Plan A — Quick Facts
Platform
Unisoc SC9863A (4G VoLTE)
Biometrics
RGB + IR Anti-Spoofing
Communication
SIP/VoLTE Intercom
Environment
Outdoor Rated, Extreme WDR
Client
A real estate technology firm needing an outdoor, 4G-connected biometric intercom system for apartment complexes.
Challenge
Ensuring secure, anti-spoofing facial recognition in varying outdoor lighting conditions (from direct sunlight to pitch black) while maintaining a reliable 4G VoLTE connection.
Product Concept & Architecture
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).
Engineering Solution
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.
Result
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.
