5. For example: To limit the area where the server is looking for motion, decrease the size of the
Default Window and drag it to center on the area of the image where relevant motion is expected.
This will limit the number of false triggers due to background motion, thus conserving disk space.
If you wish to capture all motion that the camera sees, this window can be left full screen.
Additional windows can also be added, and the windows can be set to “Include” or “Exclude”
depending on your preference. An “Exclude” window might be useful if there is a tree or flag in
the image that is frequently moved by the wind, and it is not desired to trigger and event if the
tree or flag moves.
6. For configuring the Motion Detection sensitivity there are three values that can be individually set
for all included windows, “Object Size”, “History”, and “Sensitivity”:
Object Size refers to the number of pixels that need to
change to trigger a motion event. The larger the object
size, the less sensitive the detection. It is recommended
that this be set to the minimum value possible.
History refers to the length of time a moving object
remains in the window before it is considered to be a non-
moving part of the scene. A high setting will continue to
trigger motion as long as the object is moving. A low
setting will trigger motions when the object initially moves
but then will be ignored. It is recommended that this slider
be set high somewhere above 80%.
Sensitivity refers to the difference in luminance from one
frame to the next. A low setting will only trigger motion of
there is a great difference in luminance, i.e. a bright object
suddenly appears on a dark background. It is
recommended to set this slider as high as possible.
Typically greater than 90%. This setting will most likely
need adjustment during initial setup to obtain the most
reliable motion detection.
