Network Speed
Select the network transfer rate according to the network environment to which the
NVR is connected. Select auto negotiation and the NVR will adjust the transfer rate
automatically.
Obtain the IP address settings automatically via DHCP
If the network supports DHCP, select this option and the NVR will automatically
obtain the IP address and network settings.
Use static IP address
To use a static IP address for network connection, enter the IP address, subnet mask,
and default gateway.
Jumbo Frame Settings (MTU)
“Jumbo Frames” refer to the Ethernet frames that are larger than 1500 bytes. It is
designed to enhance Ethernet networking throughput and reduce the CPU utilization
of large file transfers by enabling more efficient larger payloads per packet.
Maximum Transmission Unit (MTU) refers to the size (in bytes) of the largest packet
that a given layer of a communications protocol can transmit.
The NVR uses standard Ethernet frames: 1500 bytes by default. If the network
appliances support Jumbo Frame setting, select the appropriate MTU value for the
network environment. The NVR supports 4074, 7418, and 9000 bytes for MTU.
Note: The Jumbo Frame setting is valid in Gigabit network environment only. All the
network appliances connected must enable Jumbo Frame and use the same MTU
value.
