Resolution: The higher resolution is, the clearer the image is. The resolution options from
low to high are: QCIF, CIF, 2CIF, DCIF, 4CIF.
DS-7004HI-S: Each channel supports 4CIF@8FPS, DCIF@8FPS, 2CIF@15FPS,
CIF/QCIF@real-time.
DS-7008HI-S/DS-7016HI-S: Each channel supports 2CIF@15FPS,
CIF/QCIF@real-time.
Note: If you change this resolution option, please reboot DVR to make it become effective.
Bit Rate Type: There are two options: “Variable” and “Fixed”.
If you select variable bit rate, DVR will adjust the actual bit rate according to the video
movement. When there is not much movement, DVR will use low bit rate, while there is much
movement, DVR will use high bit rate. In this case, DVR can save HDD usage and network
bandwidth.
If you select fixed bit rate, DVR will use the fixed bit rate to compress iamge. The bit rate
size is defined in “Max Bit Rate” option. In this case, we can calculate the recorded file size and
network bandwidth that we need.
Max Bit Rate: If you select variable bit rate, when the video input has great movement, we
need to limit the max bit rate. The max bit rate has follows 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”.
The max bit rate selection has relations with resolution. If you select high resolution, you
must select 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. Of course, you will select the proper max bit rate based on the camera,
background and image quality requirement.
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.
Enable Event Para: The setting activates Event recording parameters. “×” means disable
and “” means enable the function.
Enable Rec: The setting decides whether the camera will start recording. Recording may be
halted according to the additional schedule settings.
Schedule: When you enable recording function, you can setup recording schedule.
