LAN 2 Port
LAN2
port is a typical Ethernet port. You will have to use this port to connect with a different
network segment when your system requires (1) the connection with a remote PC client or
network cameras, (2) the use of event-triggered Email service via external SMTP server (3)
the use of date/time synchronization with external NTP server.
By default, once connecting to a network, it will first try to get an IP address assigned by your
network router from DHCP server. If your network does not assign IP address automatically,
then
LAN2
port will assume IP address 192.168.1.10. Please note that every time you
connect a network via
LAN2
, you have to REBOOT ENR to refresh the IP addresses.
Connection Setting Example 2
Below diagram displays an example connection setting using
LAN1
+
LAN2
to connect
networks cameras within different network segments.
In this setting, ENR with three cameras are within the same network segment, while there is
another camera locating in another network. In addition, this system requires the connection
with an external SMTP server and a remote client.
You may check and modify the network configurations by going to
