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.

Please ensure that the MTU port does not conflict with other
