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.
