This camera comes with a built-in AGC
circuit. Setting AGC to AMidB, AHighB or
ASuperB increases the sensitivity of a dark
image, and the screen may appear grainy.
This is not a malfunction.
When this camera is used with the white
balance set to AAT WB (Auto Tracking White
Balance), the color tone of some objects may
differ slightly from the actual color due to the
principle of the automatic tracking white
balance circuit. This is not a malfunction.
If a high brightness subject (such as a lamp)
is shot, vertical lines may appear in the image
displayed on the screen (smear), or bleeding
may appear around the bright subject
(blooming). These phenomena are
characteristics of the CCD, and are not
caused by malfunction of the camera.
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 switching between color and black-
and-white images in the B&W mode, the
brighter area on the screen is emphasized,
which may reduce the visibility. However, this
is not a malfunction.
When the electronic sensitivity enhancement
feature is enabled, the screen may appear
grainy and more white spots may appear as
the sensitivity is increased. 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.
The rotation angle of this camera is increased
to enable installation at a wider variety of
locations. When the zoom of the lens is at the
wide end, and tilted at an angle close to ±80°,
a part of the camera may come into view on
the screen depending on the rotation angle.
When this occurs, adjust the field angle
accordingly.
When using multicast, make use of an
IGMPv2-compliant network switch.
Power can be supplied to this camera either
by using PoE or connecting to an AC 24 V
power supply. Make sure that power is
supplied using only one of the above
methods at any one time. Connecting
simultaneously using the power cable and to
PoE via a LAN cable may cause the camera
to break down or 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.
During viewing using the integrated viewer,
the video and audio sound may appear out-
of-sync. This is not a malfunction.
It is recommended to use shielded LAN
cables, shielded alarm cables and shielded
audio cables for connection with this product.
The safety and reliability of this product has
been checked by using shielded cables.
