Preparation

System Connection
Example
The following operations are possible with this system.
● Surveillance of up to 9 cameras (live image, recording and
playback)
● Checking recorded images on the VGA monitor
● Recording/Playing sound
● Alarm recording
● Remote surveillance using PCs
Analog cameras
Supplied power cord
AC 120-240V 50Hz/60Hz
VGA monitor
IP cameras
● You can connect up to 9 cameras, out of which a maximum of
4 analog cameras are allowed.
● You can connect up to 10 surveillance computers.
Memo :
● Connect LAN1 to the camera network.
● LAN2 to the surveillance computer network.
● For details of the protocol and port number for the network
cameras on the LAN1 network, refer to the network camera's
user manual.
● The protocol and port number used on the LAN2 network are
shown below.
● Surveillance computer: HTTP 80
● Mail: SMTP 25, POP 110
● Time Synchronization : NTP 123
● Connect NAS to the LAN1 network.
● Connect the time server to the LAN2 network.

Computer for
configuring cameras
Note :
● Connect only after having turned AOFFB the power of all devices.
● Set the IP address of the camera to 192.168.0.xxx. When setting
the IP address of the camera to an address other than
192.168.0.xxx, you must also change the IP address of LAN1.
Refer to the [Instruction Manual] of each camera for procedures
to change the camera's IP address,
● 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.
● In this unit, analog input circuitry is considered a network
encoder (IP video server), and the IP address is set to 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.
● When a single network camera is registered with multiple units
of 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-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.
