Pixel Calculator   

Click the 

Add button at the lower screen to create a pixel calculator window. Place your cursor on the 

window to move it to an area of your interest, and change the size of window to fit the area of interest.   
Once they are drawn, the numbers of pixels on the sides of windows will appear. This allows you to 

calculate if your current configuration fulfills a requirement, for instance, for recognizing the faces of 

persons passing through a location. A facial recognition usually requires around 130 pixels per meter or 

higher. 

The pixels thus calculated are listed at 

the lower screen on a per-stream basis 

depending on the frame size you configure 

for each video stream.
