Cases not suited for face matching The matching accuracy varies depending on installation, settings and adjustment of the camera, ambient environment and object. Therefore, face matching may not be performed in the following cases. • Illuminance levels are dispersed. (Example: Outdoors) • Faces are interrupted by such objects as medical masks, sunglasses or helmets. • Faces are not directed to the front side. • Photographic subjects are moving quickly. • Under the influence of strong external light (such as the headlights of a car, rising sunlight or setting sunlight) To improve the performance of face matching • Register the target face images from the images recorded by the camera installed under the same conditions. • Perform settings for the camera so that the camera can shoot face images at a balanced illuminance level both in the day- time and nighttime. • Install the camera so that the camera can move within the assumed moving pathway of photogenic subjects. • If people's faces are printed on a poster, perform the setting for "Setup area" (☞ Operating Instructions (PDF)) so that these faces are not targeted for face matching. 1 Matching area 13
