Ⅵ When shooting a bright object (eg. lamps,
etc.), white vertical streaks may appear on
the object on the screen. This is a
phenomenon (smear phenomenon) normal
to CCDs (solid-state image pickup devices)
and is not a malfunction.
Ⅵ The dome cover is hemispherical in shape, and
therefore images tend to be distorted at the
edges of the hemisphere. The edges of the
hemisphere is masked for this camera. When
the camera is tilted and pointed in the horizontal
direction, therefore, edges of the hemisphere
may enter the angle of view, hence causing
the upper end of the screen to appear dark
and the image to go out of focus.
Ⅵ When shooting an object that is near a light
source (eg. lightings) or with a large
difference in brightness, ghosting may occur
on the screen. This phenomenon is due to
the characteristics of the dome cover and
built-in lens and is not a malfunction.
Ⅵ Ensure to use the Converter Unit that has
been supplied.
Ⅵ Certain Hubs/switches that are equipped with
the SNMP feature may come with a broadcast
or multicast control function. Proper viewing
of multicast images created by this camera
may not be possible if this function is enabled.
Ⅵ Do not touch the dome cover with your hand.
This may dirty the cover and cause the image
quality to deteriorate.
Ⅵ To clean the camera.
• Do so upon turning off the power.
• Use a lens cloth (or paper) to remove dirt
from the dome cover. The camera may
acquire dirt over a short period of time,
depending on the environment of use.
When there is excessive dirt, wipe using a
lens cloth (or paper) upon wetting it in a
neutral detergent diluted with water.
Ⅵ If the D/N switch is turned on, the mode
changes automatically to black and white in
dark places. As the sensitivity increases, the
image may look grainy and white spots may
appear. When changing modes, bright
portions of image may be emphasized but
this is not a failure of the camera.
Ⅵ The unit is to be powered by a DC 12 V or an
AC 24 V power supply.
The AC 24 V power supply should conform to
the following : Class 2 only (For USA), Isolated
power supply only (For Europe).
Ⅵ The rating label is displayed on the underside
of the body.
Install at places that are strong enough
to support the camera weight.
Install this camera at places that are strong
enough to support its weight upon taking
into consideration the vibration force during
high-speed rotation as well as its mass
(approx. 1.0 kg). For ceiling materials that
are weak, such as overlay plywood and
plaster boards, reinforce by applying
reinforcements (veneer plywood). If
reinforcement is inadequate, image on the
monitor screen may be blurred due to
vibrations. In the worst scenario, it may even
fall and cause serious injuries if there is
someone underneath.
Warning
Ⅵ JVC will not be liable for any damage resulting
from the camera dropping due to incomplete
installation by not following the installation
instructions. Take caution when performing
installation.
Ⅵ Before starting an important recording, be sure
to perform a test recording in order to confirm
that a normal recording is possible.
Ⅵ We do not accept liability for the loss of a
recording in the case of it becoming impossible
to record due to a problem in the video camera,
VCR or video tape.
Ⅵ We do not accept liability for any damage to
the camera in cases when it is dropped
because of incomplete installation due to not
observing the installation instructions correctly.
Please be careful when installing the camera.
Ⅵ Read Me
Please read through the "Read Me" file in the
CD-ROM together with this instruction
manual.
Ⅵ Image sending may be affected when this is
done on a network where multicast
transmission devices are connected, or on
networks for which there is transmission of
voluminous broadcast data. When this
occurs, ensure to employ a system design
that separates the camera from other
multicast or broadcast devices by making use
of a switching valve or VLAN with a multicast
control function.
Ⅵ When using the local recording feature with
a CF card, turning off the power during local
recording may damage the file. To prevent
damage of the file, make use of a UPS
(uninterruptible power supply).
