4-Inch Face Recognition Terminal
Recognizes faces at 99.98% accuracy in 200–300 ms using dual RGB and IR cameras — the IR camera keeps recognition accurate in complete darkness, no added lighting required. Carries an IP65 rating for outdoor and industrial environments, and integrates via Wiegand 26/34, RS485, or TCP/IP into existing access control platforms.
0.1s Paim Vein, 200‑300ms Face Recognition
200-500mm Recognition Distance(Palm vein), 0.3-5m Recognition Distance(Face), Face recognition speed reaches 200‑300ms, palm vein recognition responds in 0.1s. Built‑in 4‑spot infrared sensing ensures stable capture under complex lighting conditions.
Dual‑Biometric Solution
Palm vein & facial recognition dual‑biometric solution. Face recognition works at 0.3-5m within 200‑300ms response. Palm vein identification achieves 0.1s fast recognition. With 4‑spot infrared sensing, it realizes stable, contact‑free, high‑security identity verification for access control.
Open APIs . Support Custom Development.
Wiegand 26/34 output connects directly to third-party access control platforms and time-attendance systems — no firmware modification needed. RS485 serial communication handles multi-device bus installations. TCP/IP via RJ45 Ethernet or WiFi 2.4 GHz connects to network-based management systems. USB 2.0 port available for data transfer and peripheral connections.
Techniical Specifications
Face Presented. Matched. Gate Opens. 4 Steps.
The 4-Inch Face Recognition Terminal runs the full recognition loop locally in 200–300 ms — no cloud round-trip on the access decision.
Step 1 — Presence Detection
The IR camera detects a person at 0.5–3 m. Liveness detection verifies a live human is present — not a photo, screen, or mask.
Step 2 — Recognition
The RGB camera captures the face. The onboard processor compares it against up to 50,000 stored templates at 99.98% accuracy. The decision is made locally in 200–300 ms.
Step 3 — Access Signal
A match triggers a relay switch output, Wiegand 26/34 signal, or RS485 command to the connected gate, door lock, or access control system. The gate opens or the lock releases.
Step 4 — Record & Reset
The access event is logged locally and synced to the connected management platform. The terminal resets and is ready for the next user within milliseconds.
