Profile Setting

The Video Profile Settings control the ROI (Region of Interest) characteristics. The

ROI video is streamed via RTSP protocol. See the “Streaming ROI” section for

more on viewing ROI video.

The number of available ROI profiles for viewing can be set by selecting the

appropriate option button.

4 Profile defines each stream with a VGA resolution (640x480), while 1 Profile

and 2 Profile settings provide some options for resolution.

Setting for specific ROI profiles can be found in the Video Quality Setting section.

ROI profile 1 & 2 are preconfigured profiles which have some settings that are

configurable (e.g. FPS).

All profiles offer Constant Bit Rate (CBR) or Variable Bit Rate (VBR) mode.

The GOP (Group Of Pictures) can also be adjusted. The GOP is based on the FPS

setting. For example, if the FPS is 20 and the GOP setting is 2, then the GOP is 40

frames. A GOP is comprised of one I frame and the remainder are P frames.
