Connecting to the AC 24 V power
supply
Connect this product to the AC 24 V power
supply when the PoE is not used.
Caution:
● Make sure to select only one mode of
electrical supply. Connecting the power cord
and the LAN cable for the PoE at the same
time may result in failure or malfunction of the
camera.
● The unit is to be powered by 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 and
others).
ⅷ Power cord
● To prevent misconnection and detachment of
cords, use a lug plate to connect the cord to
the terminal.
● When a two-core VVF (vinyl insulated vinyl
sheath cable) is used, the connection
distance is as follows. (Reference value)
Note:
● After DHCP timeout, all IP addresses of
VN-V25Us are set to 192.168.0.2 by default.
When the power of multiple cameras within
the same LAN environment are turned on at
the same time, the IP address of the cameras
overlap, thus preventing proper access. As
such, make sure to turn on the power of the
cameras one by one.
● In a system where multiple units of VN-V25U
are used, turn on the power of only one unit
to configure the IP address settings using the
Internet Explorer. Upon doing so, turn on the
power of the second unit and configure
accordingly. Configure the camera settings
using the same procedure.
● When overlapping of the IP address occurs,
check to ensure that there is only one
VN-V25U unit within the same LAN
environment, and wait for a while (at least 10
minutes) or power off and on all network
devices under the same LAN environment.
Otherwise, access to VN-V25U may fail.

The rated power of this product is AC 24 V,
50 Hz/60 Hz. Make sure to use it with the
correct voltage.
Use an AC 24 V supply that is isolated from
the primary power supply.
Supplying a power beyond the rated value
may result in failures, smoke or fire. When the
camera breaks down, turn off the power and
