Sulfurization caused by rubber products
Do not place the product near rubber products
(packing, rubber feet, etc.) that contain sulfur.
There is a risk that sulfur components in rubber
products may cause electrical parts and termi-
nals, etc. to become sulfurized and corrode.
Screw tightening
• The screws and bolts must be tightened
with an appropriate tightening torque
according to the material and strength of
the installation area.
• Do not use an impact driver. Use of an
impact driver may damage the screws or
cause tightening excessively.
• When a screw is tightened, make the
screw at a right angle to the surface. After
tightening the screws or bolts, perform
checks to ensure that the tightening is
sufficient enough so that there is no
movement or looseness.
Heater unit
This product is equipped with an internal heat-
er unit for use in cold climates. The heater unit
turns on automatically when the temperature
inside the product drops below around 0 °C
{32 °F}. When this product is installed and
operated in low temperatures below –20 °C
{–4 °F}, it may require time to start up since the
camera will wait to be warmed up internally by
the internal heater right after the power is
turned on. Also, the camera may not function
properly, if it is installed and operated in an
environment where the temperature is below
–30 °C {–22 °F}. In such a case, wait approxi-
mately 2 hours or more until the camera is
warmed up. Then, turn on the power again.
As the camera warms up, snow or frost accu-
mulated on the front cover will melt. However, it
may not be defrosted from the cover depend-
ing on the ambient temperature or weather
condition.
Effects on images and image quality
Under the following conditions, image quality
may deteriorate or images may become diffi-
cult to see.
• Effects of rainfall
During rainfall, it may be difficult to see
images when there are raindrops on the
front cover due to wind.
• Effects of snowfall
During snowfall, there may be snow on the
front cover due to wind, which makes sur-
veillance images difficult to see (varies
depending on the amount and quality of
snowfall).
• Effects of dust in the air or gas emission
from vehicles
Depending on the installation environment,
the image quality may deteriorate when the
front cover is dirty from dust in the air, gas
emission from vehicles, etc.
• Effects of strong light
When the camera is facing toward a spot
light or other bright lights and light reflect-
ing objects, ghost images (a phenomenon
where objects that do not actually exist
appear in images) may appear. In particu-
lar, ghost images may be more noticeable
when the camera is facing toward an LED
light.
Protection from lightning
When cables are used outdoors, there is a
chance that they may be affected by lightning.
In such a case, install a lightning arrestor close
to the camera, and make the length of the net-
work cable between the camera and lightning
arrestor as short as possible to prevent the
camera from being damaged by lightning.
Take notice of humidity
Install this product when the humidity is low. If
installation is performed when it is raining or in
very humid conditions, the inside may be
affected by humidity, causing mist-over inside
the front cover
When noise disturbance may happen
Conduct the power distribution work to keep a
distance of 1 m {3.28 feet} or more from the
120 V (for U.S. and Canada) or 220 V – 240 V (for
Europe and other countries) power line. Or con-
duct the electric conduit work separately (Always
connect the metal pipe with grounding).
Radio disturbance
Noise may appear in video or audio near a
strong electric field from a TV or radio antenna,
motors and transformers, or a strong electric
field/magnetic field from a power line (lamp line)
of AC100 V or more.
