DEFAULT SETTINGS:
NTSC
Overwrite
The device records video cyclically. This drop
list enables you to specify the conditions
whereby older video will be overwritten:
By Days
– video older than a specified
number of days will be overwritten by
newer video. Selecting this will enable
a numeric text field where you can
specify the number of days to keep
video retained before overwriting.
By Capacity
– video will be retained
as long as storage capacity is
available. As device storage capacity
runs out, older video data will be
overwritten by newer video data in
First In First Out (FIFO) format.
Never
– video will never be
overwritten. In order to ensure that
the device still has storage to record
new video, you will have to download
and remove the older video on a
regular basis.
DEFAULT SETTINGS:
By Capacity
Lock Duration
Numeric text field setting the lock duration for
video data. If the lock duration is set, then
video will always be retained for at least this
duration regardless of the Overwrite settings.
DEFAULT SETTINGS:
7 days
Pre-Recording
Checkbox – if selected will enable the pre-
recording feature, so that when alarms/events
occur, video data leading up to the incident is
available as well.
Selecting this checkbox will enable a drop list
where you can specify the duration of video to
pre-record.
