TCP/IP stands for Transmission Control Protocol/Internet Protocol and it is the language/protocol that allows
communication between internet connected devices, whether on a local network, or a on the Internet at large.
This screen allows for TCP/IP settings to be modified for the NVR to establish connection to the network.
Below is a screenshot of the TCP/IP settings screen:
Below is an explanation of the fields on the TCP/IP settings screen:
•
MTU: MTU stands for Maximum Transmission Unit. This field allows the user to set the MTU value of the network
adapter. The value ranges from 1280-7200 bytes. The default value is 1500 bytes. Please note MTU modification may
result in network adapter reboot and the network turning off. MTU modification can affect the current network
service. The system may pop up a dialog box to confirm setup when the MTU value is changed. Click the OK button
to confirm current value and reboot or can click the Cancel button to terminate the current modification. Before the
modification, you can check the MTU of the gateway; the MTU of the NVR should be the same or lower than the
MTU of the gateway. This way, packets can be reduced, and the network transmission efficiency be enhanced. The
following MTU values are for reference only.
