Record Days
】
This section allows users to determine how long the
record data of each camera should be kept
in the system. The maximum
duration for on-line storage is 120 days. Users can select an exact number of
days, or
select “auto” mode. If select “auto”, system will auto-delete the
recorded data of the earliest days when there is no enough space.
Note:
If there is no enough space of HDD, system will delete the record data
according to the length of saving time of each camera. E.g.: there are four
cameras, the 1
st
camera is set to say for 2 days, the 2
nd
camera saves for 5
days, the 3
rd
camera saves for 10 days, and the 4
th
camera is set “auto” mode.
When the space is enough, the 4 cameras’ record data will be saved in HDD.
When there is no enough space, system will delete data automatically. If the 4
th
camera’s record data has been saved more than 10days, system will delete
the 4
th
camera’s data. If the 4
th
camera’s record data has been saved less than
10 days, but the 3
rd
camera’s data is more than 10 days, system will delete the
3
rd
camera’s data. So, even if you set the 3
rd
camera’s record data to be saved
for 10 days, the data that is saved less than 10 days become possible. System
