Important: You can add the same camera to more than one group. However, there is no
parallel recording across HDDs. When a camera is in more than one group and the first HDD
fails, the second HDD only then takes over the recording of that camera.
Dual streaming capacity
You can set up the recorder so that it records both main stream and substream. Doing so will
allow you to, via the browser or TruVision Navigator, get access to the substream in both live &
playback. You are also able to set the dual stream ratio. This can be useful, for example, if you
have bandwidth limitations as you can then adjust the ratio to record more substream than main
stream.
To set up dual streaming mode:
1. From the menu toolbar, click Configuration > Remote Configuration > Storage
Management > Storage Mode.
2. Under the Mode option, select Dual Streaming.
Note: The recorder will reboot automatically if you change the HDD mode.
3. Under Capacity Ratio, use the mouse to adjust the main stream/substream storage ratio.
By default, the ratio is 50:50.
Move the slider left/right to adjust the capacity ratios
4. Click Save to save the settings.
S.M.A.R.T. settings
S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) reports on a variety of hard
drive attributes. It helps ensure that the HDD is functioning properly at all times while protecting
video stored on the hard drive.
Note: A recorder with RAID functionality does not support S.M.A.R.T.
To view the S.M.A.R.T. information of a HDD:
1. From the menu toolbar, click Configuration > Storage Management > S.M.A.R.T.
