Motion Detection 

When a camera is running, Netcam Watcher Professional is constantly 

comparing frames, looking for motion. It displays the amount of motion on the 

Motion Detection Bar at the bottom of the screen. 

You can adjust the motion detection settings by clicking on the bar graph. 

There are three sliders that let you control three parameters: 

Cell Size. The picture is divided into square cells, and each cell is 

compared. This slider controls how large the cells are. This can range 

from 4x4 pixels to one large cell that covers the whole picture. Smaller 

cell sizes mean more CPU required, but better motion discrimination. 

Percentage of cells changed determines how many cells need to be 

changed before the picture is considered different. This slider adjusts the 

position of the red and green bars on the Motion Detection Bar Graph. 

Sensitivity controls how sensitive to motion the bar graph is.
