Max Bit Rate
The max bit rate has many options (bps): 32K, 48K, 64K, 80K, 96K, 128K, 160K, 192K, 224K, 256K, 320K, 384K, 448K, 512K, 640K, 768K, 896K, 1M, 1.25M,
1.5M, 1.75M, 2M and “User define”.
If setup to variable bit rate, when the video input has great movement, we need to limit the max bit rate. The max bit rate has relation with resolution. That means high
resolution needs high bit rate. For CIF resolution, the typical max bit rate is 384K-768Kbps. For DCIF resolution, the typical bit rate is 512K-1Mbps. For 4CIF
resolution, the typical bit rate is 1Mbps-1.5Mbps.
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 requires
high bit rate support.
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 and 1/16. Low frame rate match low bit rate.
PreRecord Time
Setup enable motion detection record or external alarm record, you can define PreRecord time. The options are: No PreRecord, 5 Seconds (default setting), 10 Seconds,
15 Seconds, 20 Seconds, 25 Seconds, 30 Seconds and Max PreRecord.
MaxPreRecord is to save all data in PreRecord buffer. The MaxPreRecord time is related with bit rate. The lower bit rate, the longer MaxPreRecord 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 hand, if the bit
rate is high, and set “PreRecord Time” as “30 Seconds”, maybe the actual PreRecord time is less than 30 seconds.
PostRecord Time
Setup enable motion detection record or external alarm record, when external alarm or motion alarm has stopped, NetDVR will continue recording for a predefined
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. “X” means disable and “
9
” means enable.
Schedule:
When enable record function, you can setup record schedule.
