Description
If there are several HDDs installed to the Device, you can set one
of the HDDs as the redundant HDD to save the recorded files
into different HDDs. If one of the HDDs becomes damaged, you
can find the backup on the other HDD.
● Select Main Menu > STORAGE > Disk Manager, and then set
a HDD as redundant HDD.
● Select Main Menu > STORAGE > Schedule > Record, and
then select the Redundancy checkbox.
If the selected channel is not recording, the redundancy
◇
function will take effect the next time that you record,
whether or not you select the checkbox.
If the selected channel is recording, the current recorded
◇
files will be packed, and then start recording according to
the new schedule.
● This function is for some models only.
● The redundant HDD only backs up the recorded videos but
not snapshots.
You can set the ANR (auto network resume) function.
● The IPC continues recording once the NVR and IPC
connection fails. After the network becomes normal, the
NVR can download recording files while it is disconnected
from the IPC. This is to help protect against data loss from
the current IPD channel that is connected.
● Set the maximum recording upload period. If the offline
period is longer than the period you set, IPC will only upload
the recording file during the specified period.
Make sure that SD card is installed and the recording function is
enabled on the IPC.
Set a period during which the configured recording setting is
active.
The system only activates the alarm in the defined period.
