Door Station Install Condition
The Door Station cannot be installed in a place that
hard/large light sources can cover the lens of the
camera(for exmaple, the street light or Sun light),
otherwise the video image will be poor quality. If there is
no way to avoid this condition, the alternative is to install
the Door Station in a higher position and then adjust the
camera angle towards down to keep the lens away from
the light source.
