TCP/IP
From main menu->Setting->Network/TCP/IP, the interface is shown as in Figure 3-93.
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. Right now, the value here is for read-only.
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.

download speed is 1.5X or 2.0X of the normal speed.
Important

value shall be 128-digit. It shall not be left in blank.
