camera. E.g., if the resolution of the front-end camera is 720p, then the encoding
resolution of the main stream will adjust to 720p automatically.
‒
The resolution of 960 × 1080 (1080P Lite) is available when the 1080P Lite is enabled in
the
Record>Advanced Settings
interface (refer to
Chapter 5.12 Configuring 1080P
Lite
).
‒
Please refer to the
Appendix-Specifications
for the supported resolutions of different
models.
<Bitrate Type>: Set the bitrate type to <Variable> or <Constant>.
<Video Quality>: Set the video quality of recording, with 6 levels configurable.
Note:
The Stream Type, Resolution, Bitrate Type and Video Quality are not configurable for the
Main Stream (Event) of the IP Camera.
<Frame Rate>: Set the frame rate for the recording.
Note:
‒
For GD-RT-AC3004N and GD-RT-AC3016N, when the 3 MP signal input is connected,
the frame rate of the main stream cannot exceed 15 fps.
‒
For GD-RT-AP5004P, GD-RT-AP5008P, GD-RT-AP5016N, GD-RT-AT5016N, when the 5
MP signal input is connected, the frame rate of the main stream cannot exceed 12 fps.
When the 4 MP signal input is connected, the frame rate of the main stream cannot
exceed 15 fps.
‒
The minimum frame rate for main stream is 1 fps.
<Max. Bitrate Mode>:
Set the mode to <General> or <Custom>.
<Max Bitrate (Kbps) >:
Select or customize the maximum bit rate for recording.
<Max. Bitrate Range Recommended>:
A recommended max. bit rate range is provided for
reference.
<Max. Average Bitrate (Kbps) >:
Set the max. average bit rate which refers to the average
amount of data transferred per unit of time.
<Video Encoding>:
You can configure H.264 or H.265 for the main stream (continuous) of IP
and analog cameras.
Note:
When the connected IP camera does not support H.265, only H.264 can be seleted for the
main stream (continuous).
3.
Check the checkbox of <Enable H.264+> or <Enable H.265+>
to enable this function. Enabling
it helps to ensure the high video quality with a lowered bitrate.
Note:
‒
The analog and IP cameras support the enabling of H.264+/H.265+, if the video encoding
is H.264/H.265 for the main stream.
