800-18160 - A - 06/2014

DHCP Used to automatically search for the IP address. When the

DHCP function is enabled, you can not modify the IP address,

Subnet mask, or Gateway. If you have not enabled DHCP, the

IP address, Subnet mask, and Gateway are all 0 by default.

To view the current the IP information, you must turn off

DHCP.

You can not modify the IP address, Subnet mask, or Gateway

if you are using PPPoE.

TCP Port Default is 37777. This value is configurable.

UDP Port Default is 37778. This value is configurable.

HTTP Port Default is 80.

RTSP Port Default is 554.

Note If you change and any of the above port settings, you must reboot your NVR to

activate those saved settings. Please ensure that the these port settings do not

conflict.

Max Connection The NVR can support up to 20 users. 0 means that this NVR

can not connect to any PC or other device.

MTU Configure the MTU value for the network adapter. Select from

1280 to 7200 bytes. The default is 1500 bytes.

Note MTU modification can affect the current network

service. Click OK to confirm a reboot, or click Cancel

to cancel the modifications.

Note Before configuring the MTU for the NVR, check the

gateway’s MTU. The NVR’s MTU should be the same

or lower than the MTU’s gateway. This helps to reduce

the number of packets and increases network

transmission efficiency.

MTU Values (reference

only)

1500: The Ethernet information packet maximum value. This

is also the default value, especially where there is no PPPoE

or VPN. This is also the default setup for some routers,

switches, or the network adapter.

1492: The recommended value for PPPoE.

1468: The recommended value for DHCP.

Please ensure that the MTU port does not conflict with other

ports.

Preferred DNS Server Enter the preferred DNS server IP address.

Alternate DNS Server Enter an alternate DNS server IP address.

Transfer Mode Select a priority, either Fluency or Video Quality.

LAN Download If you enable this function, the NVR can process the
