Parameters
Description
Encoder Type
Select the encoder‟s compression type.
MPEG-4 / MJPEG / H.264
Resolution
Select the video resolution of the IP device.
Frame rate
Select the available frame rate from the drop down menu.
Video Bit Rate
Mode
Select the video bit rate mode.
Constant Bit Rate: The bit rate remains constant at all conditions.
Variable Bit Rate: The video bit rate will vary based upon scene
complexity and amount of movement. The quality will remain the same.
Quality
When encoder type is MPEG4 or H.264, and video bitrate mode is
“Variable Bit Rate” Select the quality value from High / Medium / Low
GOP Length
When encoder type is MPEG4 or H.264. and video bitrate mode is
“Variable Bit Rate”. Select the Interval between two I-frames. This is also
called GOP Length. (Group of Picture) . Default value is one I frame per
second. The maximum length of GOP is limited to 60.
Frame rate
Select the available frame rate from the drop down menu.
This puts a hard cap on the maximum bit rate allowed in any given
second of video streaming. Assigning a limited bit rate may result in a
few dropped frames rate when the stream data overflows the allowed bit
rate. Doing so will also disable Bit Rate setting below.
Video Bit Rate
Mode
Select the video bit rate mode.
Constant Bit Rate: The video bit rate remains constant at all
conditions.
Variable Bit Rate: The video bit rate will vary based upon scene
complexity and amount of movement. The quality will remain the same.
Video Max
Bitrate
This puts a hard cap on the maximum bit rate allowed in any given
second of video streaming. Assigning a limited bit rate may result in a
few dropped frames rate when the stream data overflows the allowed
bit rate. Doing so will also disable Bit Rate setting below.
Video Bitrate
This is the target bitrate that the camera will attempt to provide when
using Constant Bitrate mode. The actual value will fluctuate slightly
based on scene changes.
Frame rate
(Stream2)
Select the frame rate for each profile by choosing from the drop down
list. Frame rates available for stream 2 may be less than stream 1,
depending upon the setting.
Quality
When encoder type is MJPEG:
Select the quality value of MJPEG encoder type from 1 to 100.
