3.3.3 Encode
The Encode menu interface is shown in Figure 3-7. The following is a list of configurable
values:
Channel: Select the channel you want to configure, the default is channel 1.
Compression: Non-configurable, the default is H.264.
Resolution: The G4-HDE series DVR supports various resolutions that you can select
from the dropdown list. Supported resolutions are D1/CIF/QCIF. Please note that the
resolution options may vary based upon channel number.
Frame Rate(FPS): You may select the value for Frames Per Second. Frames per
second values may vary based upon channel number and resolution.
Bit Rate Type: The G4-HDE series DVR supports two bit-rate types: CBR and VBR.
CBR stands for Constant Bit Rate which means the DVR will always use this bit rate
without regard to the video image. VBR stands for Variable Bit Rate which means that
the DVR will adjust the bit rate according to the video image, e.g. more motion or a
more complex image will utilize a higher bit rate. If VBR mode is selected, you can set
the video quality.
Quality: There are six levels ranging from 1 to 6. The sixth level has the highest image
quality. This option will only be displayed if VBR is chosen for Bit Rate Type.
Bit Rate(Kb/S): The bit rate is defined as the maximum amount of information or detail,
which is stored per unit of time of a recording. A higher bit rate will allow a better
image to be produced but will use more resources such as HDD storage and network
bandwidth.
Audio/Video: You can enable audio for the main stream or video/audio for the extra
(sub) stream. Video for the main stream is always enabled by default and is not
configurable. For extra stream, enable the video first and then enable audio.
Overlay: The overlay menu will allow you to create masks to block out portions of the
image for privacy and also to define the location of the time and date and channel
name labels on recorded video.
