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.
