Zoom Operation
0
The following phenomena are the results of the
built-in lens performance and are not
malfunctions.
0
When manual operation or preset is selected,
focus moves slightly after the zoom operation
has stopped near the TELE edge.
0
Manual zoom operation is not smooth.
0
When Preset is selected, the camera
becomes out of focus for an instant during
zooming.
Others
0
This camera will perform the initial operation of
pan/tilt/zoom upon powering on. It takes about
90 seconds before the initial operation starts.
This is not a malfunction.
0
Do not subject the lens to strong light source
such as sun rays. This may cause the equipment
to malfunction.
0
This camera comes with a built-in AGC circuit.
The sensitivity increases automatically at a dark
place and noise may become noticeable on the
screen. This is not a malfunction.
0
While AGC is activated, if a transceiver which
causes strong electromagnetic wave is used
near the camera, the picture may suffer from
beat. Please use the camera more than three
meters away from such transceivers.
0
When this camera is used in the White Balance
“ATW-Narrow”, “ATW-Wide” or “ATW-Full”
(automatic adjustment) mode, the color tone
may differ slightly from the actual color due to
the principle of the automatic color temperature
tracking white balance circuit. This is not a
malfunction.
0
If a high brightness object (such as a lamp) is
shot, the image on the screen may have white
vertical tailings. This phenomenon (smear) is
characteristic of solid-state image sensors and
is not a malfunction.
0
Do not touch the dome cover with your hands.
Dirty covers will cause image deterioration.
0
The dome cover may fog up due to the drastic
change of temperature when humidity is high.
0
Noises from an external source may cause the
alarm to malfunction even when the alarm signal
cable used is within 50 m. In this case, move the
cable away from the noise source.
0
Depending on the stop position and rotation
speed of the horizontal/vertical rotation
platform, the running sound of the rotation
platform’s motor may be heard, but this is not a
malfunction.
0
When using multicast, make use of an
IGMPv2-compliant network switch.
0
Some switching hubs 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.
0
The electronic shutter of this product is set to
“1/30” by default. For regions with a commercial
power supply frequency of 50 Hz, switch to
“Flickerless” during use under fluorescent lights
(excluding inverter lighting equipment) to
prevent flickers.
0
The dark areas on the screen may appear grainy
or white spots may increase. 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.
0
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.
0
As the dome cover is of a semiglobular shape,
image distortion will occur at the hemispherical
edge. When the hemispherical edge of this unit
is masked and horizontal level is shot in a tilt
direction, the hemispherical edge will enter the
field angle. This may cause the upper edge of
the screen to become black and the focus
unclear. In this case, you can avoid shooting the
above area by using the Tilt Limit settings.
0
When shooting objects with a luminance
difference or near a light source, ghost may
occur on the screen. This is a feature of the
dome cover and the built-in lens, and is not a
malfunction.
0
In particular, manual and auto pan operation
near the TELE edge (telephoto side) may cause
the screen to vibrate (unsmooth rotation). This
is a feature of the motor and is not a malfunction.
0
As long magnification lens is used in this
product, the focus may be unclear due to
temperature changes but this is not a
malfunction.
0
Preset the focus under an environment with a
temperature closest to that in your actual usage.
If the temperature change is large and the focus
becomes unclear, preset the focus again before
using the product.
0
If you sense that the focus has become unclear
due to temperature changes, use the Auto
Focus function or reset the focus manually.
0
The time of the internal clock may be
significantly out of alignment if the power of the
product is turned off for a long time or when there
is prolonged power failure. If this occurs,
readjust the clock time.
