Definition of Recording Space
(1) SD card space used by current recording mode. Normal
recording will force deleting loop recording space when the
space is not enough for its operation. When this happened,
system will display warning LED and sound for the insufficient
memory space.
(2) Loop recording cannot delete other files on the memory card.
It can only delete older loop recording files to make room for
the current recording.
(3) If use a brand-new memory card in loop recording, the whole
SD card space can be used for loop recording.
(4) When SD card is full while in loop recording mode. If you stop
recording and try to start normal recording again.
Then system will delete older loop recording files to make
space for the normal recording.
Suppose a 16G SD card is used for the system, it can save
video files for around 120 min.
Eg. 1: For loop recording only, it can save video files for 120 min
and can do the loop recording continuously.
Eg.2 : For normal recording only, it can save video files up to
120 min, then the “could not recording” LED and warning sound
will prompt by the system. You need to replace the SD card in
order to continue recording.
Eg. 3: If you loop recording for 100 min, then do a normal
recording for around 100 min. Under this case, the system
will use the left 20 min for the normal recording, then delete
older loop recording files total of 80 min to make room to do the
