Why does my DVR show "Disc
Full" but the DVD-R disc still have space??
Ans:
Because of the hardware
design, one DVD-R disc could only backup up to 41 files. If
you want to backup over 41 files to the disc, you would meet
this issue.
Note: Our DVD-RW drive only supports
"DVD-R" discs.

Why does my DVR show HDD full
with the usage of only 100GB, but the HDD total capacity is
250GB?
Ans:
It happened when you set up
motion trigger recording on the Wavelet series DVRs. The
motion list can only include up to 6,144 record items. The
least time to be recorded is 10 seconds for each triggering.
So, if you have motion triggered all the time, it will treat
as HDD full when the motion list is full.

Why does the OSD on Model
AVC787 show HDD remaining space, but not the available
remaining time?
Ans:
Because the format of MPEG
(not pictures) is different from the format of JPEG
(pictures), the available remaining time cannot be calculated.
The situation is just like downloading files from the
Internet. When you download one file from the Internet, the
displayed downloading time keeps changing. For this reason,
the remaining time varies dramatically, and users might have
the difficulties to precisely know the actual remaining time.
Therefore, our R&D team decides to use HDD remaining space
instead of the available remaining time.

failed. And in order to let HDD booting successful, the DVR

recommended to change another HDD or re-install your HDD.
