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 73).
●
In VR-N900U, analog input circuitry is considered as a network
encoder (IP video server) and the IP address is set to
192.168.201.12 by default. 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.
