Video Settings
Video format
Supports 50HZ, 60Hz and OSD (OSD = Format set by menu on camera OSD). Default: OSD
Video Coding
Support
both “
baseline
”
and
“
mainprofile
”
formats for H.264 video encoding.
Baseline is typically used for video conferencing.
2)
First Stream
Resolution
Set the desired video stream resolution. The first stream allows 1920x1080 (1080p), 1280x720 (720p) or
1024x576. The second stream allows 720x576, 480x270 or 320x240. Higher resolutions will consume more
bandwidth.
Bit Rate
Users can assign the bit rate of the stream (from 32
–
6144 kbps). Higher bit rates will provide for a higher
quality image, if your network bandwidth is sufficient to support the rate.
Frame rate:
Users can specify the maximum frame rate (fps or frames per second). Higher frame rates provide smoother
video but require higher bit rate settings.
I key frame interval:
Affects the quality of the video compression. This setting defines how many predicted frames will be used for
each actual frame (from 2-150). Shorter intervals increase video quality at the cost of requiring higher bit rates
in order to look good.
Bit Rate Control method:
Constant bit rate: video encoder will encode at a constant rate as set in bitrate setting
Variable bit rate: video encoder will encode at a variable rate with maximum as set in bit rate setting, allowing
for low motion scenes to use less bandwidth.
Fluctuate level
This setting affects how aggressive variable bit rate adjustments will be (1-6). Spikes that are too large may
affect video quality. Low levels will not save on as much bandwidth.

Second Stream
(See parameters for first stream).
