Frame Rate:
configure the maximum frame rate in video streaming. Higher frame rate gives a better
video in terms of smoothly moving objects/scenes. However, this would result in higher bandwidth and
storage requirement.
Intra Frame Period:
is applied only in MPEG4 / H.264 which the video stream is composed of
I
-
frames (full image information) and
P
-frames (motion-compensated difference information). This
setting configures the
Intra Frame Period
which is the time period between 2 I-frames. The shorter
period means the higher frequency of I-frame. Video can then be well handled while bit rate may
increase.
Video Quality:
select the way of bit rate control to adjust the video quality, the Constant Bit Rate
(CBR) or Variable Bit Rate (VBR). The selection of CBR mode concerns about the circumstances of
fixed data rate transferring. VBR, on the other hand is utilized when network bandwidth is less
concerned. CBR is not applicable in MJPEG video mode.
Video Overlay
The camera supports stamping text information on the video images. The date/time string or/and a
line of text message (e.g. Camera Name or View location) are available to be selected for displaying
or hiding on the images.
The strings are placed on the video image as header / footer in left, middle or right position. The text
color, background color and transparent level to the image can also be configured.
