Precautions
• Do not point the camera at the sun, as the
internal CCD component may be
damaged.
• Do not touch the lens surface. Use a
specialized soft cloth to gently wipe off
the lens surface as necessary.
• Avoid direct shooting of intense light
emitting objects, e.g., mercury lamps.
When shooting at strong lights, a vertical
line pattern will show up on the image,
although this is not a camera
malfunction.
• The eclipse phenomenon occurs with the
camera. This is because a sufficient
amount of aperture is not available due to
the CCD size and the lens structure.
However, it has been verified that the
eclipse will not be visible in the case of a
more than 90% effective image.
• Install the unit away from interference
sources and please adjust the video cable
or reinstall if the screen image results in
interference.
• Do not remove the serial number label
from the unit, as this may invalidate the
warranty.

Precautions / Typical CCD Phenomenon
Typical CCD
Phenomenon
The following phenomena that may appear
in images are specific to CCD (Charge
Coupled Device) image sensors. They do
not indicate malfunctions.
White flecks
Although the CCD image sensors are
produced with high-precision technologies,
fine white flecks may be generated on the
screen in rare cases, caused by cosmic rays,
etc.
This is related to the principle of CCD
image sensors and is not a malfunction.
The white flecks especially tend to be seen
in the following cases:
–when operating at a high environmental
temperature
–when you have raised the gain (sensitivity)
–when using the slow shutter
Vertical smear
When an extremely bright object, such as a
strong spotlight or flashlight, is being shot,
vertical tails may be produced on the
screen, or the image may be distorted.

Bright object (e.g.,
strong spotlight, vertical
tails shown on the
image, strong reflected
light, flashlight, the sun)
Aliasing
When fine patterns, stripes, or lines are
shot, they may appear jagged or flicker.
