Checking after Operation
A light shielding cushion is attached to the lens so that the lens is not
exposed to infrared light directly. After adjustment, when attaching the
dome cover and the lens cover, make sure that the light shielding
cushion is attached correctly with the taper (tilted) side facing up (refer
to the figure below).
If the light shielding cushion is not attached correctly or deformed,
infrared light reaches to the lens, causing the recorded images to look
shiny white.
