NVR Networking
The NVR has two network ports, LAN1 and LAN2. Two networking solutions are
possible, private camera networking mode and open network mode.
Solution 1: Camera Private Networking Mode
A private network for cameras only include the IP cameras, switch and the VHDIPL, it
does not include any other network devices. The network is especially used to transmit
audio and video of the IP cameras to the VHDIPL. The private network for cameras
must be connected from LAN2 (G2) of the NVR to the LAN2 (G2) private network
port for cameras on the dedicated switch (by default, it is enabled upon delivery). For
details of the configuration, see quick setup in the
NVR User Manual . The NVR can be
accessed through LAN1.
Once setup in private networking mode on LAN2, the NVR will perform the following
operation:
!
Enable the DHCP service and automatically assigning IP addresses to IP cameras
(the DHCP function is enabled on the IP cameras).
!
Automatically searches for IP cameras in the network.
!
Automatically adds IP cameras found on the local network and sets 7*24-hour
recording.
