Note: GOP length refers to the video frames between one completely encoded I frame
and other compressed P frames. The GOP length is usually equal to the number
of frames in one second. Using longer GOP length may save bandwidth
consumption, however at a risk of losing a portion of one GOP should the
network drop frames before the video refreshes. Long GOP is available only in
Constant FPS mode and variable Bit Rate in MPEG-4
3.3.6 Video Adjustment
The video adjust section of the user interface allows fine tuning to the web browser
video display. By clicking “Motion Enable” the user can also set motion trigger
parameters.
Select the desired brightness, saturation and contrast levels by either selecting from
the pull down menu or clicking on the blue bar. The video will adjust upon selecting
the desired level. Within the Activity window, the red line shows the baseline activity
level of the trigger threshold for the Runtime MD profile while a blue line records the
minimum activity for the Event MD profile. When the activity goes beyond the
minimum (red and blue lines), the various triggers will respond. Configure these
layers by clicking on “Motion Enable”
Three different regions can be set for enabling motion detection. Within each region,
the user can set the sensitivity, interval and threshold of the trigger. These values
can be set the same for each region or can be switched between Runtime Profile and
Event Profile via the Event handler.
