ⅷ 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.
ⅷ 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.
ⅷ Electricity can be supplied to this product
either by connecting the AC 24 V power
supply or using the PoE. 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.

ⅷ 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.
ⅷ 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.
ⅷ
The electronic shutter of this product is set to
A
1/30
B
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.
ⅷ When the Black-and-white mode (VN-V26U)
or Easy Day and Night mode (VN-V25U) is
enabled, the image becomes black-and-white
in a dark place. 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.
ⅷ
If the power supply voltage is momentarily cut
off or reduced due to lightning, turning on of
the air conditioner’s power, etc., the image
may be disrupted or noise interference may
occur.
ⅷ
When using multicast, make use of a
IGMPv2-compliant network switch.
ⅷ
In the case of VN-V26U, the image and sound
may not synchronize when playing back using
built-in viewer. This is not a malfunction.
ⅷ
When VN-V26U is sending high bitrate, the
image and sound can be paused during
Black-and-white mode changing. This is not a
malfunction.
