0
ensuring that all the connections are in place.
Do not supply power through the power cable
0
and LAN cable at the same time.
If multiple cameras are turned on
0
simultaneously in the same LAN environment,
access attempts may fail due to IP address
duplication. Set up an IP address by either using
the JVC-VN-IP SettingTool (included on the
supplied CD-ROM) or turning the power supply
of each camera on separately to avoid
duplication.
Caution
To supply power to this product, make use of AC
24 V 50 Hz/60 Hz, DC 12 V or PoE
(IEEE802.3af). Make use of the correct voltage.
Be sure to use an AC 24 V or DC 12 V supply that
is isolated from the primary power supply circuit.
Supplying a power beyond the rated value may
result in failures, smoke or fire. If the camera
breaks down, turn off the power and contact our
service center immediately.
When a power beyond the rated value is
supplied, the internal components may be
damaged even if no abnormality is found on the
appearance and operation of the camera.
Please contact our service center immediately
for servicing (charged separately).
