Images at night are dark
and faces cannot be
identified. R Even when the lobby station's LED lights are lit, because the light from
the LED lights cannot illuminate the edges of the visible area (the areas
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 angle that the lobby station is installed may help reduce this
problem.
