Note :
● Do not connect LAN1 to the internet. If the internet is
busy or the relay equipment fails, you may not be able to
save important camera images. To maintain full recording
capacity, it is recommended that a dedicated network be
used. Be sure to connect the LAN1 camera network to
the same segment. (Do not use the address translation of
NAT and NAPT etc. or a router.)
● If you connect LAN2 to the internet from a surveillance
computer, you will need to configure IP Masquerading.
● Communication between LAN1 and LAN2 is not possible.
Nor is it possible to configure a camera connected to
LAN1 from the surveillance computer connected to LAN2.
In order to configure a camera connected to LAN1, it is
necessary to connect the computer for configuring
cameras to LAN1.
● LAN1 and LAN2 are incompatible with QoS. Sound may
not be played normally depending on the condition of the
circuit.
● The default LAN1 IP address is 192.168.0.253 and the
default LAN2 IP address is 192.168.1.253. To change the
address, use [OS Setting] (A Page 68).
● In this unit, analog input circuitry is considered a network
encoder (IP video server), and the IP address is set to
192.168.201.12. When altering the IP address of LAN1
and LAN2, specify an address (different segment) other
than 192.168.201.0 to 192.168.201.255. Also make sure
that the same segment is not specified for LAN1 and
LAN2. (VR-N900U)
● When a single network camera is registered with multiple
units of VR-N1600U/VR-N1600E/VR-N900U, recording
may not be properly completed in some cases. Camera
control (e.g. PTZ control) may also become unstable. It is
recommended that a single VR-N1600U/VR-N1600E/VR-
N900U be used for registering one IP camera as well as
for controlling PTZ operations.
● Do not connect a broken hub, router or deteriorated
network cable etc. Doing so may prevent the system from
operating properly.
● Connection to a keyboard is not recommended.
