► How does motion detection work?

A

D

There are two motion detection parameters: 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

detect slight movements while smaller sensitivity settings will neglect them� 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 a high level of security management, it is suggested to use higher sensitivity settings and smaller percentage values�
