If a high luminance object (such as a lamp) is
shot, a white smear may appear at the upper
and lower ends of this object on the screen.
This phenomenon (smear) is characteristic of
solid-state image sensors, and is not a
malfunction.
Some hubs/switches of products that are
equipped with intelligent features may
include a broadcast/multicast suppression
function. Viewing of multicast images on this
product may fail if this function is enabled.
Electricity can be supplied to this product
either by using the PoE or connecting the AC
24 V power supply. Make sure to select only
one mode of electrical supply. Connecting
the power cord and the LAN cable for the
PoE at the same time may result in failure or
malfunction of the camera.

This product comes with a built-in AGC
circuit. When using this product with AGC set
to AMidB, AHighB or ASuperB, the sensitivity
level increases when the image is dark, and
the screen may appear grainy as a result.
However, this is not a malfunction.
When using this product with the white
balance set to AATWB, the displayed color
may differ slightly from the actual color
according to the condition of the object due to
the principle of the automatic tracking white
balance circuit. This is not a malfunction.
The electronic shutter of this product is set to
A1/30B by default. For regions with a
commercial power supply frequency of 50 Hz,
switch to the flickerless mode during use
under fluorescent lights (excluding inverter
lighting equipment) to prevent flickers.
When the Easy Day and Night feature is set
to AOnB, the image turns black-and-white in a
dark location. As the sensitivity level is
increased in this case, the screen may
appear grainy and more white spots may
appear. When switching between color and
black-and-white images, the brighter area on
the screen is emphasized, which may reduce
the visibility. However, this is not a
malfunction.
If the power supply voltage is momentarily cut
off or reduced due to lightning or turning on of
the air conditioner's power, the image may be
disrupted or noise interference may occur.
When using multicast, make use of a
IGMPv2-compliant network switch.
