What does the error log "Recording error(WCK):" indicate in WJ-NX200, NX300 and NX400? And what are the cause and countermeasure?


Recorder displays "Recording error(WCK):" when:
- it has not received the image data
- recording fails due to HDD failure
This error occurs even when the recorder and camera are communicating correctly.
Estimated causes:
- The network communication lacks bandwidth
- Mismatched compression methods (under both of following conditions):
      * When [Connection method] = "RTSP" or "Internet mode"
      * When [Compression] of recorder = "H.265", [Stream encoding format] of camera = "H.264"
- Failure due to worn-out HDDs
- Separate the section with lack of bandwidth.
  Lower the value of image quality or rate for recording conditions of the camera is use.
  Check the performance of Hub.
- Use the same compression method for camera and recorder
  Setting procedure in recorder:
   [Maintenance] -> [System management] tab -> [Other] -> Click [Execute] button of [Synchronize the camera's settings with this unit]
- Check errors in HDDs
   If you see "Write error" or "SMART warning" in the error log, your HDDs may need to be replaced.
   Contact your dealer for HDD replacement.
