Preset Positions
The is a total of 100 preset positions that can
be set, including the home position.
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.
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).
Warning
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. 1.2 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.
