ⅷ This product has a built-in AGC circuit. When
AGC is
AOnB, the product sensitivity
increases automatically at dark places and
the image on the screen may appear grainy.
This is not a malfunction.
ⅷ When White Balance is set to AAutoB, the
principle of automatic tracking white balance
circuit may cause the color of the image to be
different from the actual color of the object,
depending on the condition of the object.
However, this is not a malfunction.
ⅷ If a high-intensity object (such as a lamp) is
shot, vertical lines may appear on the image
(smear phenomenon) or blurring may occur
around the high-intensity object (blooming
phenomenon). This is a CCD characteristic
and is not a malfunction.
ⅷ The electronic shutter of this product is set to
1/60 by default. To prevent flickering under
fluorescent lighting (except inverter
illumination) in a location with commercial
power frequency of 50 Hz, switch the shutter
speed to 1/100. (The sensitivity decreases a
little when the shutter speed is 1/100.)
ⅷ When Easy Day and Night is set to AOnB, the
image becomes black and white in dark
locations. As the sensitivity is increased at
this time, the screen may appear grainy and
white spots may also increase. In addition,
when color images are changed to black and
white, bright areas of the screen are
emphasized and they may be difficult to see.
However, this is not a malfunction.
ⅷ The image may be distorted or be mixed with
noises when the power voltage is cut off
instantaneously or is lowered by a lightning
strike or by switching on an air conditioner.
ⅷ When this product is moved from a cold place
to a warm room, condensation may occur
and the product may not operate properly. In
this case, leave it for an hour under room
temperature before turning on the power.
ⅷ The rotation angle of this product is set to
wide angle to support wide range equipment.
When the lens zoom is wide and the tilt angle
is approximately ±70
Њ, the rotation angle may
cause part of the product to be reflected in
the image.
In this case, adjust the field angle if required.
(
ⅷ To prevent fogging caused by temperature
changes, be sure to put the supplied silica gel
at the specified location. (
ⅷ When multicast is in use, use the IGMPv2-
compliant network switch.
ⅷ Electricity can be supplied to this product
either by using the PoE or connecting to the
DC12 V power supply. Make sure to select
only one mode of electrical supply.
Connecting the power cable and the LAN
cable for the PoE at the same time may result
in failure or malfunction of the camera.
