Video Streams
The configuration for video streams, including resolution, framerate and
image quality parameters can be found under Video & Audio> Video Streams.
The page is split into settings for 2 streams. Common settings are:
•
Video format - The compression format for the video stream.
o
H.264 - Provides the best compression, and clear picture, but
is processor intensive.
o
MPEG4 - Provides more compression that MJPEG, but loses
picture quality.
o
MJPEG - Provides minimal compression, with the best picture
quality. Each frame is stored as a discrete JPEG.
•
Video Resolution - Sets the resolution of the video output. 4 options
are available: D1 (720x480, Stream 1 only), VGA(640x480),
QVGA(320x240) , QQVGA(160x120, Stream 2 and MPEG4 only).
•
Video Frames per Second - Sets the number of frames per second. 1,
3, 5, 10, 15, 20, 25, 30 FPS are possible values.
•
Key Frame Interval - Sets the period between minimally compressed
recovery frames that don't require other video frames to decode. 1/4s,
