Hello there.
Here is the solution:
(Assume you set the configuration on the camera with no Encryption Key.)
Set the primary target to SD Flash Card or Buffered MxFFS, Then Archive target to SMB/CIFS for example.
In the field of Archive size, enter a number for amount of space for Archiving; BUT this number must be a multiple of 4GB.
Other settings are up to your project plan.
Press the Set button and Store the configuration on Camera Flash and then Reboot the camera.
Follow the link below:
Now in MxMC, enter the Edit mode and by right-clicking on that specific camera, check that the camera has found its own folder on the File Server Path. (There should be some recording by camera to create the folder on File Server in order to archive the recordings there.)
And now playback the recording.
That’s all!
