directly next to the lobby station), faces of people may not be
identifiable even when they are close to the lobby station.
→ We recommend installing extra lights in the area around the lobby
station.
–
The images of people's
faces are dark.
RImages of people's faces appear dark when there is strong sunlight or
a backlight in the area around the lobby station.
