How does motion detection work?
A

D
There are two parameters for setting the motion detection: Sensitivity and Percentage.
In the illustration above, frame A and frame B are two sequential images. Pixel differences between the two frames
are detected and highlighted in gray (frame C), and will be compared with the sensitivity setting. Sensitivity is a value
that expresses the sensitivity to moving objects. Higher sensitivity settings are expected to sense a slight movement
while smaller sensitivity settings tend to neglect it. When the sensitivity is set to 70%, the Network Camera defines the
pixels in the purple areas as “alerted pixels” (frame D). Percentage is a value that expresses the proportion of “alerted
pixels” to all pixels in the motion detection window. In this case, 50% of pixels are identified as “alerted pixels”. When
the percentage is set to 30%, the motions are judged to exceed the defined threshold; therefore, the motion window
will be outlined in red.
For applications that require higher security management, it is suggested to set higher sensitivity settings and smaller
percentage values.
