Note:
1. This is a
reference only, not an absolute numbers.
2. Activated one
channel can be connected to a camera, a switcher, or a quad system.
3. Video
resolution is same at CIF (352x288). Video quality is based on different
ways of temporal compression techniques, not based on different
resolution of a picture.
4. Recording
duration can be extended upon less movements/changes of images, B/W
camera, and lower fps time-lapse recording mode.
5. At continuous
mode recording, 30~2 fps is depend on the level of movements or changes
between successive frames. To H.263, 30 fps versus 2 fps means no
difference in speed. 30 fps means that images change all the time and 2
fps means that images rarely change. So, 30fps and 2fps are all
"real time" like.
6. 0.1fps means
one frame per ten seconds. To set this, forces SVR to make one frame per
ten seconds. 0.2fps means two frames per ten seconds. (Similar with the
rest).
