First, use the viewer software included with the SDK to confirm that the camera is operating normally and that there are no issues with the camera or the system environment.
If the camera and environment are working correctly, the issue may be related to the sample program you created. Please gather the following information and contact technical support:
Name of the sample program you used as a reference
Details of the problem
Error messages (if any)
Development environment (OS, compiler, SDK version, etc.)
