Bit rate:
You can select bit rate size for fixed bit rate type. It is the same
as “Max Bit Rate”.
Image Quality:
If you select variable bit rate type, you can define image
quality. There are 6 options: Highest, Higher, High, Average, Low and
Lowest. High image quality needs high bit rate size.
Frame Rate:
Frame per second. Options are: Full (PAL is 25 FPS and
NTSC is 30FPS), 20, 16, 12, 10, 8, 6, 4, 2, 1, 1/2, 1/4, 1/8, 1/16. For low
frame rate, you can select low bit rate size.
PreRecord Time:
When you enable motion detection recording or
external alarm recording, you can define prerecord time. The options are:
No PreRecord, 5 Seconds (default selection), 10 Seconds, 15 Seconds, 20
Seconds, 25 Seconds, 30 Seconds and Max PreRecord.
MaxPreRecord is to save all data in PreRecord buffer. The PreRecord time
is related with bit rate. The lower bit rate, the longer PreRecord time is.
If the bit rate (Max bit rate) is very low, and you select “PreRecord Time”
as “5 Seconds”, maybe the actual prerecord time is more than 5 seconds.
On the other side, if the bit rate is high, and set “PreRecord Time” as “30
Seconds”, the actual prerecord time maybe is less than 30 seconds.
PostRecord Time:
When external alarm or motion alarm is stopped, DVR
will continue recording time. The options are: 5 Seconds (default), 10
Seconds, 30 Seconds, 1 Minute, 2 Minutes, 5 Minutes and 10 Minutes.
Enable Rec:
Enable or disable selected camera record function. “×”
means disable and “
9
” means enable.
Schedule:
When you enable recording function, you can setup recording
schedule.
Note: When the camera’s recording schedule is modified, you must reboot
DVR to make it into effective.
