(2) Influence by snowfall
During snowfall, there may be snow on the
dome cover due to wind, which makes
surveillance images difficult to be viewed
(varies depending on the amount and
quality of snowfall).
(3) Influence by dust in the air or gas emission
from vehicles
Depending on the installation environment,
dome cover may become dirty due to dust
in the air or gas emission from vehicles.
This may degrade the quality of images.
(4) Influence by high-intensity light source like
sunlight
Due to the incidence angle of the high-
intensity light source like sunlight or a light-
ing lamp, a picture that does not exist
(reflected light) may enter the camera and
create a phenomenon called ghosting in
the screen. This phenomenon noticeably
appears with LED lighting in particular.
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 dome 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.
