Max connection: system support maximal 128 users. 0 means there is no connection limit.
MTU: It is to set MTU value of the network adapter. The value ranges from 1280-7200 bytes.
The default setup is 1500 bytes. Please note MTU modification may result in network
adapter reboot and network becomes off. That is to say, MTU modification can affect current
network service. System may pop up dialog box for you to confirm setup when you want to
change MTU setup. Click OK button to confirm current reboot, or you can click Cancel button
to terminate current modification. Before the modification, you can check the MTU of the
gateway; the MTU of the DVR shall be the same as or is lower than the MTU of the gateway.
In this way, you can reduce packets and enhance network transmission efficiency.
The following MTU value is for reference only.
1500: Ethernet information packet max value and it is also the default value. It is the
typical setup when there is no PPPoE or VPN. It is the default setup of some router,
switch or the network adapter.
1492: Recommend value for PPPoE.
1468: Recommend value for DHCP.
Preferred DNS server: DNS server IP address.
Alternate DNS server: DNS server alternate address.
Transfer mode: Here you can select the priority between fluency/video qualities.
LAN download: System can process the downloaded data first if you enable this function.
The download speed is 1.5X or 2.0X of the normal speed.
Dual network adapters mode:
Multiple-address mode: eth0 and eth1 operate separately. You can use the services
such as HTTP, RTP service via etho0 or the eth1 usually you need to set one default
card(default setup is etho) to request the auto network service form the device-end such
as DHCP, email ,FTP and etc. In multiple-address mode, system network status is
shown as offline once one card is offline.
Network fault-tolerance: 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 need to
set one master card. Usually there is only one running card (master card).System can
enable alternate card when the master card is malfunction. The system is shown as
offline once these two cards are both offline. Please note these two cards shall be in the
same LAN.
Load balance: In this mode, device uses bond0 to communicate with the external device.
The eth0 and eth1 are both working now and bearing the network load. Their network
load are general the same. The system is shown as offline once these two cards are
both offline. Please note these two cards shall be in the same LAN.
Important
For the IP address of IPv6 version, default gateway, preferred DNS and alternate DNS, the
input value shall be 128-digit. It shall not be left in blank.
After completing all the setups please click save button, system goes back to the previous menu.
