  1. Make sure the hard disk tray is correctly locked in VioStor.
  2. When only one hard disk is installed, make sure the disk is installed in the tray of HDD1 (two-bay model).  The HDD1 should be installed on top of the HDD2.
  3. Check if the recording function is enabled in “Camera Configuration” page (the function is enabled by default).  Make sure the IP address, name and password are correct.
  4. If the above items are verified to work properly while the status LED flashes green, the hard disk(s) may be damaged or cannot be detected.  Please turn off the server and install a new hard disk.

Note: If you have updated the configurations of VioStor, recording will be stopped temporarily and restart again shortly.
