Displays the video stream protocol. You can modify the video
stream protocol, as needed.
For dual stream cameras, select the stream to view. Usually,
stream 1 or Channel ID 1 is configured to be the best quality
stream for recording purposes and stream 2 or Channel ID 2
with basic quality for live viewing, like viewing through
DSS-1000. Once the Channel ID is selected, the succeeding
camera properties, such as encoder, resolution, etc., change
according to the compression settings of the selected stream.
Displays the video stream encoder type. You can modify the
encoder type for the current stream, as needed. Note that for
local viewing, only H.264 is supported.
Displays the video stream resolution. You can modify the
resolution, as needed. Note that for local viewing, only up to 2
megapixel (1920 x 1080) is supported.
This is the amount of frame per second of the video stream. You
can modify the frame rate, as needed.
Under “Constant Bit Rate” mode (CBR), the camera keeps the
stable bitrate regardless of the complexity of the scene. Under
this mode, the video quality may vary if the bit rate value is set
too low. It is easier to do storage and network bandwidth
consumption estimations under this mode compared to Variable
Bit Rate mode.
Under “Variable Bit Rate” mode (VBR), the camera will keep
the video quality stable while the bit rate may occasionally go up
or down, depending on the complexity of the scene.
Max Bitrate
(only for H.264)
The bitrate will be floating slightly under that limit. For example,
if the limit is set as 2M, the bitrate will be floating around 1.6~2.0
Mbps. If the Max Bitrate is “Unlimited”, then the Bitrate
selection box will appear that defines the bit rate level.
When Max Bitrate is “Unlimited”, the user can define the
AVERAGE bit rate. For example, if the Bitrate is 2M, then
occasionally, the actual bit rate may go below or beyond 2M, but
in the long run, the average bit rate will be very close to 2M.
This mode allows the most accurate storage estimations,
