Detection Range Characteristics of the Motion Detection Feature
• Motion detection becomes more difficult as it becomes darker.
• The motion detection function works by detecting changes in contour and brightness in moving
objects. This is done in order to reduce inaccurate detections due to changes in brightness.
• The camera can easily detect motion when objects move sideways in front of the camera, but
cannot easily detect motion when objects move toward the front of the camera.
