Troubleshooting Procedures

Check Cable Connections

Device Cable Description of proper cable connection

Camera

Power cable

PWR indicator light is solid green.

Ethernet cable

V3 cameras: ETH indicator light is either green (gigabit network) or yellow (megabit network).

V4 cameras: LINK indicator light is blinking or solid green.

Computer

Ethernet cable

The indicator light of the Ethernet port is lit.

Router/Network switch

Ethernet cable

Cable is connected to an Ethernet port (router)/access port (network switch), and the indicator light of the port is lit.

  • If the camera and computer are connected directly, you do not need to check for the cable connection of the router/network switch.

  • If the LINK/ETH indicator light of the camera blinks several times and goes off, and this phenomenon recurs, please check the connection of Ethernet cable(s). This phenomenon is usually caused by Ethernet cables not fully inserted into ports.

Check Windows Defender Firewall and Antivirus Software

Procedure:

  1. Configure Windows Defender Firewall: You can turn off Windows Defender Firewall completely, or unblock Mech-Eye Viewer in Windows Defender Firewall.

    • Turn off Windows Defender Firewall:

      Select Control Panel  System and Security  Windows Defender Firewall  Turn Windows Defender Firewall on or off  Turn off Windows Defender Firewall, and then click OK at the bottom to turn off the firewall.

    • Unblock Mech-Eye Viewer in Windows Defender Firewall:

      1. Select Control Panel  System and Security  Windows Defender Firewall  Allow an app or feature through Windows Defender Firewall  Change settings, and then click Allow another app... at the bottom to open the Add an app page.

      2. Click Browse,navigate to the installation path of Mech-Eye Viewer, and select Mech-Eye Viewer.exe. Click Add to finish.

  2. Check antivirus software: If an antivirus software is running, please turn it off.

IP Addresses of Multiple Ethernet Ports in the Same Subnet

Procedure:

  1. Disable Ethernet ports not connected to the camera.

    On the computer, select Control Panel  Network and Internet  Network and Sharing Center  Change adapter settings. The Network Connections page will be displayed. Right-click an Ethernet port and select Disable.

  2. Open Mech-Eye SDK and connect to the camera.

  3. If the camera is successfully connected, one or more of the disabled Ethernet ports have IP address in the same subnet as the port connected to the camera. Enable the other ports one at a time and connect to the camera in Mech-Eye SDK each time. The camera connection will fail when the Ethernet port with the problematic IP address is enabled. Please change the IP address of this Ethernet port to a different subnet.

If the camera still cannot be connected, disable the Ethernet port connected to the camera and enable it again. If the camera still cannot be connected afterward, connect the camera to a different Ethernet port.

Restart the Camera

If the camera still does not show up after the above procedures have been performed, please try restarting the camera.

Restart procedure:

  1. Unplug the power cable from the camera.

  2. Wait for about 20 seconds, and plug the power cable into the camera.
