Stream Setting
Note: Configuration of stream 2 is the same as stream 1, but Stream 2 can only be set
to 320x240 or 640x480.
z
RTSP Path
The RTSP Path is the stream ID used for RTSP client streaming connection, such as
VLC player. The default values are v00, v01 and v02 for the three streams
respectively. The string can be any combination of number or capital/small letters. It
cannot be empty however.
z
Resolution
The resolution here describes an image size counted by width and height, e.g.
640x480, referring to pixel resolution. The 1st stream can be set from more options
of resolution; 1600x1200 (2 megapixels), 1280x720(HD), 800x600(SVGA),
640x480(VGA), 320x240(QVGA), while Stream2 has the options of VGA and QVGA.
z
Video Mode
This option allows the selection of two bit rate modes, the Constant Bit Rate (CBR) or
Variable Bit Rate (VBR). CBR refers to the setting of a fixed Target Bit Rate
(configuration in the rage of 64Kbps to 6Mbps) that would apply in the case of limited
bandwidth or/and storage requirement. While CBR concerns a fixed data rate
transmitting, the video quality is of high priority for VBR mode selected. VBR
therefore is configured with the Quality Level (Standard, Good, Best). In general,
CBR predicts the provided condition; if image activity requires higher bit rates than
configured, the frame rate and quality would be affected as not likely to increase
bandwidth (bit rate). In spite of the required recording storage estimation, VBR is by
way of compensation that adjustable bit rate fits the actual image activity.
