How does motion detection work?
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.
