The variable rate can adjust the bandwidth that it occupies automatically
according to the complexity of image, because the complexity of real video
sequence keeps changing, details, speed, etc, and the variable rate setting mode
can be used to choose how much bandwidth should be used. If the video gets
more details and moving fast, then it takes up more bandwidth to transmit, and
reversely it occupies less bandwidth. When the setting goes with constant bit
rate, then the image is transmitted under a constant bandwidth.
Bit Rate Upper Limit:
You have to set the upper limit of bit rate if “vbr” is
selected; the stream size will be fixed if “cbr” is selected and the stream size is
defined in the “Bit Rate Upper Limit”. For major stream, the bit rate upper limit
can be 1000kbps~10000kbps; for minor stream, the bit rate upper limit can be
256Kbps~ 2000Kbps.
Image Quality
: it can be set under MJPEG stream. Options: Highest, High, Average,
Low and Lowest. The higher the image quality is, the more bandwidth it will occupy.

Context: Enter the text content in the box of Context, which allows up to 40
characters (lower/upper case letters and 0~9).
X-axis &Y-axis: The title axis location. Both X-axis and Y-axis can be any of
whole numbers from 0 to 99.
Font Size: Set the font size to be displayed. The bigger the value is, the larger
the font size is. Default as: 3.

4.5.3 Privacy Mask
V6202-TA series camera supports 4 privacy masks. If there is certain location
within the surveillance area where operators are not allowed to see, and thus,
Privacy Mask can be applied. System covers and shields the sensitive area via
Privacy Mask setting, to avoid operators observing certain sensitive locations on
monitor.
Note: do turn on privacy mask function in Live View interface before
privacy mask setting (see Section 4.1).

How to set the privacy masks:
Tick the box of motion detection area number. Click the button “Draw” with
the mouse, press the left mouse button and drag on the video till a blue frame
