This article explores enterprise face recognition access control through four high-impact office scenarios: meeting room anti-occupancy control, R&D/server room protection, executive area access, and hybrid attendance integration. Using SUNTEK FA5 as the reference model, it explains how a compact 5-inch terminal can deliver better installation flexibility and cost efficiency than larger 8-inch or 10-inch alternatives for most indoor deployments. The article also highlights FA5’s practical capabilities, including Android 13 architecture, 1.0 Tops NPU-assisted liveness detection, GDPR-oriented privacy design, and 4-in-1 multimodal verification (Face, App, QR, RFID/IC). For organizations planning Linux-based infrastructure, it notes that FL5 is in preparation and recommends contacting SUNTEK sales for roadmap updates.
