User Manual of DS-91/90HFI-ST/RT/XT & DS-81/80HFI-ST & 91/90/81HWI-ST Series DVR
11.6 Configuring Frame Extracting Mode
Purpose:
If you want to extend the record time of the HDD, you can set the storage mode of the HDD to Frame Extracting.
In this mode, the bitrate of frame extracting record is less than 1/8 of that of normal record and the frame rate of
frame extracting record is 1 fps so as to maintain longer storage time of the record files.
Notes:
1)
This chapter is only available for DS-9100/8100HFI (HWI)-ST & DS-9100HFI-RT/XT series.
2)
If you set the storage mode as Frame Extracting, you may only find the frame extracting record of low bitrate
and frame rate at certain time period.
Steps:
1. Enter the Storage Mode interface.
Menu>HDD>Advanced
2. Set the Mode to Frame Extracting.
Note:
The device must be rebooted to activate the change.

3. Drag
to adjust the storage percentages of normal record, frame extracting record and picture according
to actual requirements.
4. You can edit the bitrate of the camera and the Allowed Record Time and Extended Record Time will change
accordingly.
Allowed Record Time: The total recording time that is allowed when using the frame-extracting recording
mode.
Extended Record Time: The recording time that is extended when using the frame-extracting recording
mode.
Example: With the frame extracting mode configured, the Allowed Record Time is estimated as 12 and the
Extended Record Time as 10, it means the HDD capacity allows the frame extracting record to last 12 days
and the record time is extended for about 10 days. If you have not configured the frame extracting mode, the
HDD capacity allows the record to last 2 days only.
Notes:
1)
The estimation of the record time is only for reference.
2)
If you change the storage capacity of the device, e.g., a new HDD is connected or a HDD is removed,
