In cross-spectral face recognition, visible cameras capture 400–700 nm reflected light and depend on ambient illumination, whereas thermal infrared (LWIR, typically 8–14 μm) cameras capture spontaneous human emission and do not depend on lighting.

UnverifiedOrdinary camera sensors also respond to near-infrared light (about 700–1000 nanometers), but an infrared cut-off filter (IR-cut filter) is usually installed in front of the lens to filter out infrared light and restore natural colors.73% similar
