Extended Motion Detection Features
Extended Motion Detection - Enables the extended mode from the default 64 to 1024 detection zones for enhanced detection sensitivity.
Zone Size - Slider bar and numeric field determine the size of the detection zone grid displayed when motion detection feature is enabled.
Detail - Slider bar and numeric field determines the size of each zone displayed by motion detection grid contains sub zones the number of which is determined by the zone size setting up to 32x32 pixels. This setting configures the sensitivity of the motion detection to the size of objects in the image moving through the zone. Higher values will trigger motion only for larger objects moving through the zone, lower values will cause detection of smaller objects in the zone thus increasing sensitivity to smaller size objects moving through the image.
Level Threshold - Slider bar and numeric field determine the sensitivity to brightness changes between dark and light objects within each grid zone. As an example, "Detail" will set the size of the object detected within the zone, "level" sets the duration that movement must be maintained to trigger motion detection. Lower settings can increase false motion alarms caused by image noise, higher settings will require more movement to trigger a motion event.
Motion Sensitivity % - Slider bar and numeric field determine the sensitivity to sudden overall brightness changes in the image. This setting can be useful to prevent false motion alarms due to sudden exposure changes such as car headlights from triggering motion detection. Larger values will disregard larger changes affecting the entire image and smaller values will make motion detection more sensitive to large changes in the image.
