FOV (Field of View)
For a 5MP IB9381 model, the default resolution is 5 Megapixels, and if bandwidth or frame rate per
second is of the concern, you can select a lower resolution while enjoying a higher frame rate. The
other congurable options is 1080P (16:9) at 60fps.
This Network Camera supports multiple streams with frame sizes ranging from 176 x 144 to 2048 x
1536 pixels or 2560x1920 (5MP models).
The denition of multiple streams:
■ Stream 1: Users can dene the "Region of Interest" (viewing region) and the "Output Frame Size"
(size of the live view window).
■ Stream 2: The default frame size for Stream 2 is set to the 640 x 480 or 1600x1200.
■ Stream 3: The default frame size for Stream 3 is set to the 2048 x 1536 or 640 x480.
■ Stream 4: The 5MP model supports 4 video streams.
Click Viewing Window to open the viewing region settings page. On this page, you can congure
the Region of Interest and the Output Frame Size for a video stream. For example, you can crop
only a portion of the image that is of your interest, and thus save the bandwidth needed to transmit
the video stream. As the picture shown below, the area of your interest in a parking lot should be
the vehicles. The blue sky is of little value for the surveillance purpose.
