Operation
When one stream's resolution is set to 3840x2160, the camera supports the following resolutions for the
other stream:
Resolution
3840x2160
Thermal 1
Codec options are H.264 or MJPEG.
The resolution is 640x512 and the Frame Rate range is 5-30 FPS.
Codecs, Quality, and Bandwidth
The codec used determines which parameters you can set that have a
significant impact on the quality and bandwidth requirements of the video
stream. Use the default values initially, and then individual parameters can be
modified and tested incrementally to determine when bandwidth and quality
requirements are met.
With the H.264 codec, you can set the:
·
Rate Control:
o CBR (constant bit rate): The Bit Rate parameter defines the target bit rate;
the camera attempts to keep the video at or near the target bit rate.
o VBR (variable bit rate): The Bit Rate parameter defines the average bit rate.
·
I-frame Interval: Controls the number of P-frames used between I-frames. I-frames are full frames of
video and the P-frames contain the changes that occurred since the last I-frame. A smaller I-Frame
Interval results in higher bandwidth (more full frames sent) and better video quality. A higher I-frame
Interval means fewer I-frames are sent and therefore can result in lower bandwidth and possibly lower
quality.
With the MJPEG codec, you can set the Quality between 10-80. Setting a higher value can increase the
video stream's bandwidth requirements.
