It is recommended to test the Local Area Network (LAN) communication when encountering connectivity issues with you DVR or NVR. This is commonly done by trying to ping the unit over the network. However, an uncommon issue that can occur is if the target device’s Network Interface Card (NIC) is no longer working properly.
This article will outline how to test a NIC for a VMAX standalone unit using a Macintosh OS computer.
Note: If you are using a Windows OS to test the NIC, please read Standalone Network Interface Card Troubleshooting (WinOS).
Before testing the NIC of the standalone unit, make sure that the issue is not being caused by network errors such as blocked ports or IP address conflicts.
For more information:
If the recording unit cannot be reached over the LAN and you have determined that the issue is not being caused by network settings, perform the following to test the Network Interface Card (NIC):
Connect the computer directly to the LAN port of the DVR or NVR with Ethernet cable.
Note: This process cannot be performed over Wi-Fi.
To do so, open the System Preferences menu.
Select the Ethernet connection, then click on Configure IPv4.
Note: If you are unable to make changes to the settings, click on the Lock icon at the bottom of the window and enter the computer’s Administrator credentials to unlock setting controls.
Leave the Router, DNS Server, and Search Domains fields blank as this setup is just for testing purposes.
Click the Apply button to save the settings.
Using the IP address of the DVR or NVR, enter the command ping <ip address>, then press the Enter key.
If you do not receive successful pings back, there may be an issue with the NIC.
If you suspect that there is an issue with the NIC of the DVR or NVR, please contact Digital Watchdog Technical Support for further assistance.
