– Places where brightness always changes. (e.g. a light is
flickering; people are passing by in front of the camera.)
– Places where there is little contrast of brightness.
– Places where there are repeating patterns of vertical stripes.
Memo
• The focus position can be manually adjusted by using the Built-

☞
( "Instructions (Setting)") Resort to this method if it is difficult
to acquire focus automatically.
Note
• Before installing the dome cover, make sure that silica gel (supplied)
is placed inside.
• Mount the dome cover firmly. If it is not fixed securely enough, the
moisture inside the camera increases, fogging the inside of the cover
or causing the cover to fall off.
• If you remove the dome cover after installing it, the field angle may
shift. If the field angle has shifted, adjust the focus and the field
angle again.
• Pay attention to the fall prevention wire so that it will not be caught
between the dome cover and the camera. Otherwise, dust proofing
and waterproofing may not work correctly.
