Troubleshooting Information for AI Analytics Applications

September, 2022: Revised to be applicable to all i-PRO Network Camera with AI engine  

This article provides the troubleshooting information for the operation of below additional applications on i-PRO Network Camera with AI engine.
 - AI-VMD (WV-XAE200W)
 - AI Privacy Guard (WV-XAE201W)

We recommend installing cameras after the on-site verification as the detection accuracy depends highly on the installation condition, when using those applications.
Note that AI Model Training will not be performed after the installation as those applications include the results of AI Model Training.

The below table describes the issues, the possible causes and the corresponding methods when operating AI-VMD(WV-XAE200W) and AI Privacy Guard(WV-XAE201W).
