It uses pixels but you can mask off any area you want to detect motion or
not detect motion. Then you can adjust the selected areas sensitivity by
rate of motion or shade. A cat will not generate the same rate of motion or
shade as a human. The GE guy thought he was slick, on their system they had
a guy climbing a fence with a freeway in the background. They masked the
area around the freeway and set a high rate of motion for that area and a
low rate for the fence so it looked as if it was only detecting the human.
We adjust for day and night shading by automatically changing the
sensitivity settings per camera by time of day.
