Answer:
The N-UltraFace is rated for optical ambient light tolerance up to 60,000 LUX, allowing reliable face recognition in high-glare entryways and brightly lit outdoor lobbies. Its 500 DPI optical prism is engineered to capture dry, moist, coarse, and ink- or color-stained fingers without read degradation.
A critical engineering differentiator of the eSSL N-UltraFace terminal is its environmental and physical adaptation capabilities:
- High Ambient Light Tolerance: The facial recognition optical assembly is rated for operational ambient brightness up to 60,000 LUX. This prevents sensor blinding and recognition failure near perimeter gates, glass curtain walls, or brightly illuminated industrial entrances.
- Specialized Fingerprint Optics: Unlike standard optical scanners that fail when skin contact is irregular, the 500 DPI optical prism is optimized to read dry, moist, rough, and factory-stained or ink-colored fingers.
- High Capacity Ratio: The unit supports a fingerprint template capacity of 30,000 alongside its 3,000 face capacity, making it suitable for multi-shift industrial manufacturing plants with large workforces requiring primary or secondary fingerprint credentialing.
