Installing in low temperature environments
This product may not function properly if it is
installed and operated in an environment where
the temperature is –20 °C {–4 °F} or lower. If
this product does not start up even after for a
while, wait until the temperature rises to –20 °C
{–4 °F} or higher.
As the camera warms up, snow or frost accu-
mulated on the dome cover will melt. However,
it may not be defrosted from the cover
depending 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
dome cover due to wind.
• Effects of snowfall
During snowfall, there may be snow on the
dome cover due to wind, which makes
surveillance 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
dome 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.
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.
PoE (Power over Ethernet)
Use a PoE hub/device that is compliant with
IEEE802.3af standard.
Router
When connecting this product to the Internet,
use a broadband router with the port forward-
ing function (NAT, IP masquerade).
Refer to the Operating Instructions on the pro-
vided CD-ROM for further information about
