Connect this product to the AC24 V power
supply when not using the PoE.
Caution:
●Make sure to select only one mode of
electrical supply. Connecting the power cord

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 other).

Notes:
●In a system where multiple units of VN-C20
are used, turn on the power of only 1 unit to
configure the IP address settings via 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.
●Whenever duplication of IP addresses
occurs, disconnect VN-C20 units from the
LAN except 1unit. Access to VN-C20 may be
disabled for a short period of time (at least 10
minutes), unless you restore the power
supply of all network devices under the same
LAN environment.
