<Recorder Part> Basics
Devices Connected Through a
Network
This unit is connected with network cameras and
surveillance computers through the network.
This unit has two network terminals; one for connecting to
network cameras (LAN1), and one for connecting to
surveillance computers (LAN2).
Caution:
Make sure to use LAN1 and LAN2 for different segments*.
Example:
LAN1: 192.168.0.
253
LAN2: 192.168.1.253
* Segment: Underlined sections
LAN1 and LAN2 cannot communicate with each other. It
is not possible to configure settings of cameras connected
to LAN1 from a surveillance computer connected to
LAN2. Connect a computer for camera setup to LAN1 in
order to configure settings for cameras connected to
LAN1.
LAN1 and LAN2 are non-QoS-compliant. Audio sounds
may not be played back properly depending on the line
status.
Do not connect a faulty switching hub or router, or an
exhausted network cable. Otherwise, the system may
malfunction.

Network cameras
B Switching hub
Caution:
Install cameras and setup IP addresses in advance.
Do not connect LAN1 to the Internet. Important camera
images may not be saved depending on conditions such
as Internet congestion and relay status.
It is recommended to make it a dedicated network to
ensure recording performance. Also, the camera network
of LAN1 must be the same segment (address conversion
such as NAT and NAPT and a router are not used).
Note:
For protocols and port numbers used by network
cameras, refer to the instruction manual of the network
cameras.
The default IP address of LAN1 is “192.168.0.253.” The
default value may be changed in [Network and Internet] in
[Control Panel] (A Page 31).
With separately-sold camera licenses, the number of
cameras that can be connected may be increased to 64
(VR-X3200U) or 32 (VR-X1600U) (A Page 118). For
purchase of additional licenses, consult an authorized
dealer or a JVC KENWOOD service center.
Connecting to surveillance computers (LAN2)

Computer
B Switching hub
C Time server (NTP server)
Caution:
When connecting the LAN2 side to the internet and using
in on the surveillance computer, global IP acquisition and
VPN connection may require a contract with a separate
telecommunications carrier. Also, it is necessary to set the
broadband router to connect to the internet.
To use LAN2 on surveillance computer by connecting to
the Internet, an IP masquerade setup is necessary.
Note:
Protocols and port numbers used are as follows:
Surveillance computer: HTTP 80
Main sending: SMTP 25, and POP 110
Time synchronization: NTP 123
The default IP address of LAN2 is “192.168.1.253.” The
default value may be changed in [Network and Internet] in
[Control Panel] (A Page 31).
