Electricity can be supplied to this product either 
by connecting to the AC 24 V power supply or 
using the PoE (
ⅷ When power is supplied to this product, the
[STATUS] indicator at the side lights up. The 
indicator lights up in orange color during 
startup, and switches to green color after 
startup is complete.
You can select not to light up the [STATUS] 
indicator when the unit is running.
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.
● Be sure to use an AC 24 V supply that is
isolated from the primary power supply 
circuit. Using a variable voltage power supply 
will cause the camera and system to 
malfunction or breakdown.
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-V25U/26Us 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.
