1
1
Keep away from humidifier and
stove. High temperature and
humidity can cause breakdown.
When cleaning, never use wet
hands, volatile benzene or paint
thinner.
Keep picture clear by cleaning
camera window frequently with
soft cloths.
As this device consists of
electronic precision
components, and high voltage
is generated internally, do not
attempt to disassemble.
Do not drop monitor or door
camera, and avoid strong
impact.

generating strong magnetic field
(TV, Speaker, etc.) (Picture can
be disturbed or blurred and

light and counter light.
Camera must be installed at a place free from rain.
Standard height of monitor must be 1,450mm~1,500mm
from ground, centered around brawn tube.
Camera should be installed on the wall in which cement
is completely dry.
If installed during winter season at temperature below
-5, condensation might be generated inside monitor and
camera due to temperature difference between indoors
and outdoors. To prevent breakdown due to such
condensation, connection should be made in 2 hours or
more after installation.
Do not install monitor and camera in locations subject to
direct heating as harmful gases may subsequently be
emitted in significant amounts.
Stopping up pipe as above minimizes
