It is possible that your PC’s security software is blocking the GigE Vision camera connection.

Adjust the security software settings as follows and check if the camera appears:

(1) Temporarily allow communication only for the NIC (network card) connected to the camera.
(2) Temporarily disable the security software.

Important Notes:
While setting (1) is enabled, avoid using the allowed NIC for internet or intranet connections.
While setting (2) is enabled, avoid internet or intranet connections as well.

If internet/intranet access is required on the PC while connecting the camera, configure the security software to allow communication only for the NIC connected to the camera.
