Max Connection
The system supports a maximum of 128 users.
MTU
Displays the Maximum Transmission Unit (MTU) value of the network adapter. The value ranges from
1280-7200 bytes. The default setup is 1500 bytes.
MTU modification can affect current network service and may result in a reboot of the network
adapter. When you change the MTU setup, a pop up dialog box appears for you to confirm the setup.
Click the
OK
button to confirm the reboot or click
Cancel
to terminate the modification. Before the
modification, verify that the MTU of the NVR is the same as or lower than the MTU of the gateway. In
this way, you can reduce packets and enhance network transmission efficiency.
The following MTU values are for reference only.

eth0 and eth1 operate separately. You can use the services such as HTTP,
RTP service via etho0 or the eth1 usually you must set one default card (default setup is eth0) to
request the auto network service form the device-end such as DHCP, email ,FTP, etc. In multiple-
address mode, system network status is shown as offline once one card is offline.

In this mode, device uses bond0 to communicate with the external devices.
You can focus on one host IP address. At the same time, you must set one master card. Usually there
is only one running card (master card). The system can enable alternate card when the master card is
malfunction. The system is shown as offline once these two cards are both offline. Note these two
